Abstract
Objective Surgical registries play a crucial role in clinical knowledge discovery, hospital quality assurance, and quality improvement. However, maintaining a surgical registry requires significant monetary and human resources given the wide gamut of information abstracted from medical records ranging from patient co-morbidities to procedural details to post-operative outcomes. Although natural language processing (NLP) methods such as pretrained language models (PLMs) have promised automation of this process, there are yet substantial barriers to implementation. In particular, constant shifts in both underlying data and required registry content are hurdles to the application of NLP technologies. Materials and Methods In our work, we evaluate the application of PLMs for automating the population of the Society of Thoracic Surgeons (STSs) adult cardiac surgery registry (ACS) procedural elements, for which we term Cardiovascular Surgery Bidirectional Encoder Representations from Transformers (CS-BERT). CS-BERT was validated across multiple satellite sites and versions of the STS-ACS registry. Results CS-BERT performed well (F1 score of 0.8417 ± 0.1838) in common cardiac surgery procedures compared to models based on diagnosis codes (F1 score of 0.6130 ± 0.0010). The model also generalized well to satellite sites and across different versions of the STS-ACS registry. Discussion and Conclusions This study provides evidence that PLMs can be used to extract the more common cardiac surgery procedure variables in the STS-ACS registry, potentially reducing need for expensive human annotation and wide scale dissemination. Further research is needed for rare procedural variables which suffer from both lack of data and variable documentation quality.

Abstract
PURPOSE OF REVIEW The no-touch technique is an established method to harvest the saphenous vein (NT-SV), which is the most commonly used conduit in coronary artery bypass grafting. Herein, we summarize the foundational evidence, as well as highlight recent innovations and ongoing clinical trials involving NT-SV. RECENT FINDINGS Through preservation of perivascular tissue for atraumatic handling and omission of manual distension, the NT-SV maintains endothelial nitrous oxide synthase levels and experiences less vascular smooth muscle cell activation, which translates to slower progression of atherosclerosis and less size mismatch of the graft and target vessel. These biomolecular advantages allow NT-SV to provide superior graft patency compared to conventional skeletonized saphenous vein and approximating that of the radial artery. Nonetheless, the clinical benefits of NT-SV for mortality and reduction in major adverse cardiac and cerebrovascular events are insufficiently studied in the long-term. The drawback of NT-SV is the short-term harvest site complications, which may potentially be addressed by the advent of endoscopic no-touch technique. SUMMARY NT-SV is a promising conduit, and its role will be further clarified in upcoming clinical trials and as follow-up lengthens. However, conduit selection and harvest technique should ultimately be personalized to the individual patient.

Abstract
AIM The cardiac surgery-related ischemia-reperfusion-related oxidative stress triggers the release of cytotoxic reactive oxygen and nitrogen species, contributing to organ failure and ultimately influencing patients' short- and long-term outcomes. Selenium is an essential co-factor for various antioxidant enzymes, thereby contributing to the patients' endogenous antioxidant and anti-inflammatory defense mechanisms. Given these selenium's pleiotropic functions, we investigated the effect of a high-dose selenium-based anti-inflammatory perioperative strategy on functional recovery after cardiac surgery. MATERIALS AND METHODS This prospective study constituted a nested sub-study of the SUSTAIN CSX trial, a double-blinded, randomized, placebo-controlled multicenter trial to investigate the impact of high-dose selenium supplementation on high-risk cardiac surgery patients' postoperative recovery. Functional recovery was assessed by 6-min walk distance, Short Form-36 (SF-36) and Barthel Index questionnaires. KEY FINDINGS 174 patients were included in this sub-study. The mean age (SD) was 67.3 (8.9) years, and 78.7 % of the patients were male. The mean (SD) predicted 30-day mortality by the European System for Cardiac Operative Risk Evaluation II score was 12.6 % (9.4 %). There was no difference at hospital discharge and after three months in the 6-min walk distance between the selenium and placebo groups (131 m [IQR: not performed - 269] vs. 160 m [IQR: not performed - 252], p = 0.80 and 400 m [IQR: 299-461] vs. 375 m [IQR: 65-441], p = 0.48). The SF-36 and Barthel Index assessments also revealed no clinically meaningful differences between the selenium and placebo groups. SIGNIFICANCE A perioperative anti-inflammatory strategy with high-dose selenium supplementation did not improve functional recovery in high-risk cardiac surgery patients.

Effect of remimazolam versus propofol on hypotension after anesthetic induction in patients undergoing coronary artery bypass grafting: A randomized controlled trial. J Clin Anesth 2024; 98:111580. [PMID: 39126872 DOI: 10.1016/j.jclinane.2024.111580] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2024] [Revised: 08/04/2024] [Accepted: 08/05/2024] [Indexed: 08/12/2024]
Abstract
STUDY OBJECTIVE There is scarce evidence on the hemodynamic stability of remimazolam during anesthetic induction in patients with significant coronary artery disease. This study aims to compare the effects of remimazolam and propofol on post-induction hypotension in patients undergoing coronary artery bypass grafting (CABG). DESIGN Randomized controlled trial. SETTING Tertiary teaching hospital. PATIENTS Adult patients undergoing isolated CABG. INTERVENTIONS Patients were randomly allocated to received either remimazolam (n = 50) or propofol (n = 50) for anesthetic induction. The remimazolam group received an initial infusion at 6 mg/kg/h, which was later adjusted to 1-2 mg/kg/h to maintain a bispectral index of 40-60 after loss of consciousness. In the propofol group, a 1.5 mg/kg bolus of propofol was administered, followed by 1-1.5% sevoflurane inhalation as needed to achieve the target bispectral index. MEASUREMENTS The primary outcome was the area under the curve (AUC) below the baseline mean arterial pressure (MAP) during the first 10 min after anesthetic induction. Secondary outcomes included the AUC for MAP <65 mmHg and the requirement for vasopressors. MAIN RESULTS The remimazolam group demonstrated a significantly lower AUC under the baseline MAP compared to the propofol group (mean [SD], 169.8 [101.0] mmHg·min vs. 220.6 [102.4] mmHg·min; mean difference [95% confidence interval], 50.8 [10.4-91.2] mmHg·min; P = 0.014). Additionally, the remimazolam group had a reduced AUC for MAP <65 mmHg (7.3 [10.3] mmHg·min vs. 13.9 [14.9] mmHg·min; P = 0.007) and a lower frequency of vasopressor use compared to the propofol group (60% vs. 88%, P = 0.001). CONCLUSIONS Remimazolam may offer improved hemodynamic stability during anesthetic induction in patients undergoing CABG, suggesting its potential advantage over propofol for patients with significant coronary artery disease in terms of hemodynamic stability.

Abstract
INTRODUCTION We sought to explore the relationship between various surgeon-related and hospital-level characteristics and clinical outcomes among patients requiring cardiac surgery. METHODS We searched the New York State Cardiac Data Reporting System for all coronary artery bypass grafting (CABG) and valve cases between 2015 and 2017. The data were analyzed without dichotomization. RESULTS Among CABG/valve surgeons, case volume was positively correlated with years in practice (P = 0.002) and negatively correlated with risk-adjusted mortality ratio (P = 0.014). For CABG and CABG/valve surgeons, our results showed a negative association between teaching status and case volume (P = 0.002, P = 0.018). Among CABG surgeons, hospital teaching status and presence of cardiothoracic surgery residency were inversely associated with risk-adjusted mortality ratio (P = 0.006, P = 0.029). CONCLUSIONS There is a complex relationship between case volume, teaching status, and surgical outcomes suggesting that balance between academics and volume is needed.

Abstract
BACKGROUND The relationship between the number and type of postoperative complications and mortality in the setting for surgery for acute type A aortic dissection (ATAAD) remains underexplored despite its critical role in the failure-to-rescue (FTR) metric. METHODS This retrospective study used data from the Society of Thoracic Surgeons Adult Cardiac Surgical Database on ATAAD surgeries performed between January 2018 and December 2022. Patients were categorized based on their number of major complications. The primary outcome was FTR. We used multilevel regression and classification and regression tree models. RESULTS We included 19,243 patients (33% females), with a median age of 61 years. Regarding complications, 47.7% of patients had 0, 20.2% had 1, 12.7% had 2, and 19.4% experienced 3 or more. The most frequently reported complications were prolonged mechanical ventilation (30.3%), unplanned reoperation (19.5%), and renal failure (17.2%). Cardiac arrest occurred in 7.1% of cases. FTR increased from 13% in patients with 1 complication to >30% in those with 4 or more complications. Cardiac arrest (adjusted odds ratio [aOR], 10.9) and renal failure (aOR, 5.3) had the highest odds for mortality, followed by limb ischemia (aOR, 2.7), stroke (aOR, 2.6), and gastrointestinal complications (aOR, 2.4). Hospitals in the top performance quartile consistently showed lower FTR rates across all levels of complication. CONCLUSIONS The study validates a dose-response association between postoperative complications and mortality in patients undergoing surgery for ATAAD. Top-performing hospitals consistently show lower FTR rates independent of the number of complications. Future research should focus on the timing of complications and interventions to reduce the burden of complications.

Radiologists predict differential resource utilization but not clinical outcome in emergency department patients imaged with ultrasound for right upper quadrant pain. Abdom Radiol (NY) 2024; 49:2145-2154. [PMID: 38400982 DOI: 10.1007/s00261-024-04244-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 02/05/2024] [Accepted: 02/07/2024] [Indexed: 02/26/2024]
Abstract
PURPOSE Radiologists with diverse training, specialization, and habits interpret imaging in the Emergency Department. It is necessary to understand if their variation predicts differential value. The purpose of this study was to determine whether attending radiologist variation predicts major clinical outcomes in adult Emergency Department patients imaged with ultrasound for right upper quadrant pain. METHODS Consecutive ED patients imaged with ultrasound for RUQ pain from 10/8/2016 to 8/10/2022 were included (N = 7097). The primary outcome was prediction of hospital admission by signing attending radiologist. Secondary outcomes included: ED and hospital length of stay (LOS), 30-day mortality, 30-day re-presentation rate, subspecialty consultation, advanced imaging follow up (HIDA, MRI, CT), and intervention (ERCP, drainage or surgery). Sample size was determined a priori (detectable effect size: w = 0.06). Data were adjusted for demographic data, Elixhauser comorbidities, number of ED visits in prior year, clinical data, and system factors (38 covariates). P-values were corrected for multiple comparisons (false discovery rate-adjusted p-values). RESULTS The included ultrasounds were read by 35 radiologists (median exams/radiologist: 145 [74.5-241.5]). Signing radiologist did not predict hospitalization (p = 0.85), abdominopelvic surgery or intervention within 30 days, re-presentation to the Emergency Department within 30 days, or subspecialty consultation. Radiologist did predict difference in Emergency Department length of stay (p < 0.001) although this difference was small and imprecise. HIDA was mentioned variably by radiologists (range 0-19%, p < 0.001), and mention of HIDA in the ultrasound report increased 10-fold the odds of HIDA being performed in the next 72 h (odds ratio 10.4 [8.0-13.4], p < 0.001). CONCLUSION Radiologist variability did not predict meaningful outcome differences for patients with right upper quadrant pain undergoing ultrasound in the Emergency Department, but when radiologists mention HIDA in their reports, it predicts a 10-fold increase in the odds a HIDA is performed. Radiologists are relied on for interpretation that shapes subsequent patient care, and it is important to consider how radiologist variability can influence both outcome and resource utilization.

Epicardial placement of human placental membrane allografts in coronary artery bypass graft surgery is associated with reduced postoperative atrial fibrillation: a pilot study for a future multi-center randomized controlled trial. J Cardiothorac Surg 2024; 19:315. [PMID: 38824517 PMCID: PMC11143688 DOI: 10.1186/s13019-024-02822-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2024] [Accepted: 05/25/2024] [Indexed: 06/03/2024] Open
Abstract
BACKGROUND Post-operative atrial fibrillation (POAF) occurs in up to 40% of patients following coronary artery bypass grafting (CABG) and is associated with a higher risk of stroke and mortality. This study investigates how POAF may be mitigated by epicardial placement of aseptically processed human placental membrane allografts (HPMAs) before pericardial closure in CABG surgery. This study was conducted as a pilot feasibility study to collect preliminary for a forthcoming multi-center randomized controlled trial. METHODS This retrospective observational study of patients undergoing CABG surgery excluded patients with pre-operative heart failure, chronic kidney disease, or a history of atrial fibrillation. The "treatment" group (n = 24) had three HPMAs placed epicardially following cardiopulmonary bypass decannulation but before partial pericardial approximation and chest closure. The only difference in clinical protocol for the control group (n = 54) was that they did not receive HPMA. RESULTS HPMA-treated patients saw a significant, greater than four-fold reduction in POAF incidence compared to controls (35.2-8.3%, p = 0.0136). Univariate analysis demonstrated that HPMA treatment was associated with an 83% reduction in POAF (OR = 0.17, p = 0.0248). Multivariable analysis yielded similar results (OR = 0.07, p = 0.0156) after controlling for other covariates. Overall length of stay (LOS) between groups was similar, but ICU LOS trended lower with HPMA treatment (p = 0.0677). Post-operative inotrope and vasopressor requirements were similar among groups. There was no new-onset post-operative heart failure, stroke, or death reported up to thirty days in either group. CONCLUSIONS Epicardial HPMA placement can be a simple intervention at the end of CABG surgery that may provide a new approach to reduce post-operative atrial fibrillation by modulating local inflammation, possibly reducing ICU and hospital stay, and ultimately improving patient outcomes.

Abstract
This paper presents an overview of the development of an integrated patient-centred cardiac care registry spanning the initial 5 years (September 2017 to December 2022). The Netherlands Heart Registration facilitates registration committees in which mandated cardiologists and cardiothoracic surgeons structurally evaluate quality of care using real-world data. With consistent attendance rates exceeding 60%, a valuable network is supported. Over time, the completeness level of the registry has increased. Presently, four out of six quality registries show over 95% completeness in variables that are part of the quality policies of cardiology and cardiothoracic surgery societies. Notably, 93% of the centres voluntarily report outcomes related to open heart surgery and (trans)catheter interventions publicly. Moreover, outcomes after implantable cardioverter-defibrillator and pacemaker procedures are transparently reported by 26 centres. Multiple innovation projects have been initiated by the committees, signalling a shift from publishing outcomes transparently to collaborative efforts in sharing healthcare processes and investigating improvement initiatives. The next steps will focus on the entire pathway of cardiac care for a specific medical condition instead of focusing solely on the outcomes of the procedures. This redirection of focus to a comprehensive assessment of the patient pathway in cardiac care ultimately aims to optimise outcomes for all patients.

Abstract
OBJECTIVES Hypertrophic obstructive cardiomyopathy (HOCM) may be treated by septal myectomy. Cardiac surgery-associated acute kidney injury (CSA-AKI) is a common complication, but little is known about its incidence after septal myectomy. The objectives of this work were to evaluate the prevalence of CSA-AKI after septal myectomy and identify potential perioperative and phenotype-related factors contributing to CSA-AKI. DESIGN This was a retrospective database analysis with new data analysis. SETTING The study occurred in a single university academic expertise center for septal myectomy HOCM patients. PARTICIPANTS Data from 238 HOCM patients with septal myectomy operated on between 2005 and 2022 were collected. INTERVENTIONS CSA-AKI was stratified according to the Kidney Disease: Improving Global Outcomes (KDIGO) guidelines using measurement of creatinine and urine production. Important HOCM phenotype-related and perioperative factors were analyzed for their possible associations with CSA-AKI. MEASUREMENTS AND MAIN RESULTS CSA-AKI occurred in 45% of patients; of these, 55% were classified as KDIGO stage I and the remaining 45% as stage II, with no chronic kidney damage observed. Moreover, there were no phenotypical or perioperative characteristics that were more prevalent in the CSA-AKI cohort. However, the use of beta-blockers and coronary artery disease were more prevalent in the CSA-AKI cohort. CONCLUSIONS CSA-AKI is a common complication after septal myectomy but was transient, and kidney function recovered in all patients.

Abstract
The population of adults with congenital heart disease (ACHD) is constantly growing. There seems to be a consensus that these patients are difficult to manage especially if compared to patients with acquired heart disease. The aim of this study is to compare outcomes and results of cardiac surgery in ACHD patients with a reference population of adults with acquired cardiac disease. Retrospective study of 5053 consecutive patients older than 18 years hospitalized for cardiac surgery during a 5-years period in our Institution. Two groups of patients were identified. Group I: 419 patients operated for congenital heart disease; Group II: 4634 patients operated for acquired heart disease. In each Group were identified low, medium, and high-risk patients, according to validated scores. Right ventricular outflow tract surgery was the most frequent procedure in Group I, while coronary artery by-pass grafting was the most common in Group II. Patients with ACHD were younger (37.8 vs. 67.7 years), with higher number of previous operations (32.1% vs. 6.9%), had longer post-ICU hospital stay (11 vs. 8 days) but had lower ICU stay (1 vs. 2 days), shorter assisted mechanical ventilation (12 vs. 14 h) and lower surgical mortality (1 vs. 3.7%) (all p < 0.001). No differences were found in term of post-operative complications (12.4 vs. 15%). The surgical treatment of ACHD patients can be done with excellent results and if compared with acquired cardiac disease patients they have better results with shorter ICU stay and lower mortality.

Abstract
OBJECTIVE The aim of this study was to evaluate the outcome and experience of the Perceval sutureless valve at our institution (UZ Leuven). METHODS Between 2007 and 2019, 784 patients underwent sutureless aortic valve replacement using the Perceval valve (isolated or combined with other procedures). We performed a retrospective analysis of the postoperative and follow-up data. RESULTS Mean age was 78 years with a median European System for Cardiac Operative Risk Evaluation II score of 4.2% (interquartile range, 2.6%-7.2%). Isolated aortic valve replacement accounted for 45% of cases; 30% of cases were aortic valve replacement in combination with coronary artery bypass grafting and the remaining 25% were other combined procedures. The median crossclamp times were 38 minutes in single aortic valve replacement, 70 minutes in cases with coronary artery bypass grafting, and 89 minutes in multiple valve cases. Device success was 99.1% and in-hospital mortality was 3.3%. Postoperative stroke or transient ischemic attack occurred in 1.9% of patients and 1% of patients had a new need for dialysis after surgery and median survival time was 7.0 years with a cumulative follow-up of 2797.8 patient-years. The 1-, 5-, and 10-year freedom from reintervention were 99%, 97%, and 94%, respectively. CONCLUSIONS These data represent the longest follow-up available, to our knowledge, for the Perceval sutureless valve. We observed favorable early outcomes, and low rates of early mortality, stroke, and other major complications. Valve durability is promising with low rates of valve degeneration and a limited need for reintervention.

Abstract
CONTEXT It is not clear if an oral hygiene protocol to control biofilm applied before cardiac surgery can reduce infection rates. OBJECTIVE We aim to verify the effectiveness of an oral hygiene protocol in reducing postoperative infections when compared to usual practices, in patients admitted to a cardiology unit, prior to cardiac surgery. DESIGN, SETTING AND PARTICIPANTS Randomized, blind, controlled clinical trial, with 107 participants who expected to undergo cardiac surgery, randomized into two groups: Experimental Group (EG) standardized oral hygiene protocol (54) and Control Group (CG), usual practices performed in patients admitted (53). INTERVENTION a standardized oral hygiene protocol, 1 day before surgery: professional prophylaxis with a portable ultrasound device, tooth brushing and flossing plus a 0.12% chlorhexidine gluconate solution (0.12% CHX) mouth rinsing. When applicable, removable prostheses cleaning. PRIMARY OUTCOME the presence of infection. RESULTS The occurrence of postoperative infection was higher in CG = 7 (13.2%) than in EG = 5 (9.3%); but no statistical difference was found between protocols (p = 0.518). The length of stayed from surgery to discharge presented a statistical difference (p = 0.047; RR = 4.9; CI = 1.01-24.33); the percentage of postoperative infection was almost five times higher in those participants who stayed 11 or more days. CONCLUSION The standardized oral hygiene protocol with mechanical and chemical cleaning, 1 day before cardiac surgery, was not more effective than the usual practices performed regarding the reduction of postoperative infections. Other interventions regarding oral hygiene procedures before cardiac surgery must be studied to contribute to the reduction of adverse post-surgical events.

Abstract
Background Coronary artery disease (CAD) is a global health burden, contributing to mortality and morbidity. A proportion of patients with CAD suffer from diffuse CAD, where conventional revascularization techniques such as percutaneous coronary intervention and coronary artery bypass grafting (CABG) may be insufficient to adequately restore myocardial perfusion. Transmyocardial revascularization (TMR) uses a laser to create microscopic channels in the myocardium, inducing inflammation, angiogenesis, and neovascularization to improve perfusion to ischemic regions. Platelet-rich plasma (PRP) is an autologous concentrate of platelets that contains a myriad of growth factors and bioactive proteins, which have been shown to promote tissue regeneration and wound healing. The combination of TMR and PRP therapies has been proposed to synergistically enhance myocardial revascularization and functional recovery in patients with advanced CAD undergoing surgical revascularization. Methods This study evaluated the efficacy of combining TMR and PRP with CABG in improving cardiac function in diffuse CAD patients. Fifty-two patients were randomized to CABG alone (n = 16), CABG+TMR (n = 17), CABG+PRP (n = 10), and CABG+TMR+PRP (n = 9). TMR was performed using a holmium:YAG laser to create 10 channels in the inferolateral left ventricular wall. PRP was prepared from autologous whole blood and injected into the myocardium adjacent to the TMR channels. Cardiac function was assessed using speckle-tracking echocardiography preoperatively, postoperatively, and at one-year follow-up. Adverse events, including post-operative atrial fibrillation, acute kidney injury, and readmissions, were also recorded. Statistical analyses were performed to compare outcomes between the treatment groups. Results The CABG+TMR+PRP group showed significantly improved global longitudinal strain (GLS) at one year compared to CABG alone (mean GLS -15.96 vs -12.09, p = 0.02). Post-operative left ventricular ejection fraction trended higher in the TMR+PRP group (57.78%) vs other groups, but not significantly. Post-operative atrial fibrillation was higher in the TMR+PRP group (67% vs 25%, p = 0.04), potentially reflecting increased inflammation. No significant differences were observed in other adverse events. Conclusions The results of this study suggest a synergistic benefit of combining TMR and PRP therapies as an adjunct to CABG in patients with diffuse CAD. The significant improvement in GLS at one year in the TMR+PRP group compared to CABG alone indicates enhanced myocardial remodeling and functional recovery, which may translate to improved long-term outcomes. The higher incidence of postoperative atrial fibrillation in the TMR+PRP group warrants further investigation but may reflect the heightened inflammatory response necessary for angiogenesis and tissue regeneration. Prospective, randomized controlled trials with larger sample sizes and longer follow-up periods are needed to validate these findings and optimize treatment protocols. Nonetheless, concomitant TMR+PRP therapy represents a promising approach to augmenting myocardial revascularization and recovery in patients with advanced CAD undergoing surgical revascularization.

Abstract
Background New-onset postoperative atrial fibrillation (POAF) is the most common arrhythmia following cardiac surgery. POAF increases the risk of thromboembolism and stroke, as well as morbidity and mortality more generally. Despite evidence from the landmark PROTECT-AF and PREVAIL trials, left atrial appendage ligation (LAAL) is not routinely performed for thromboembolism prophylaxis in POAF, and anticoagulation remains the standard of care along with dual antiplatelet therapy. This study evaluated the efficacy of concomitant LAAL in eliminating the need for postoperative anticoagulation, regardless of POAF development, in patients undergoing coronary artery bypass grafting (CABG). Methods Between 2019 and 2021, 130 patients were selected to undergo concomitant LAAL while undergoing CABG surgery. Patients were then monitored for the incidence of new-onset POAF, and anticoagulation was strictly avoided for this indication. Demographic and outcome data were collected, with endpoints including transient ischemic attack (TIA) or stroke, death, and readmission within one year, as well as the length of hospital and intensive care unit (ICU) admissions. Results POAF occurred in 37 patients (28.5%), consistent with previous reports. However, none of the POAF patients experienced TIA or stroke during the one-year follow-up period, compared to 2 (2.15%) in the non-POAF group, a typical rate of postoperative stroke in such a patient population. No significant differences were observed between POAF and non-POAF cohorts in one-year stroke, all-cause mortality, readmission rates, or total hospital stay. Interestingly, the POAF cohort had a significantly longer mean ICU stay (4.24 vs 3.37 days, p = 0.0219), possibly due to the time required for arrhythmia control before discharge. The study population had a high mean CHA2DS2-VASc score (2.81), indicating an increased risk of thromboembolism, and a high mean HAS-BLED score, suggesting an elevated bleeding risk with anticoagulation. Conclusions LAAL appears to be an effective adjunct to CABG for thromboembolism prophylaxis in POAF. Formal anticoagulation was avoided in this study, with no significant differences in adverse events between POAF and non-POAF groups, suggesting that LAAL may be a suitable alternative to anticoagulation, especially in high-risk patients (e.g., those with elevated CHA2DS2-VASc or HAS-BLED scores). The safety and efficacy of this approach should be corroborated by larger randomized studies, such as the ongoing LeAAPS trial. LAAL during CABG may help reduce the risk of bleeding complications associated with anticoagulation while maintaining protection against thromboembolic events in patients who develop POAF.

METHODS A retrospective analysis was conducted on the clinical data of 549 patients who underwent cardiac surgery. Among these patients, 501 did not experience a stroke postoperatively (non-stroke group), while 48 developed a postoperative stroke (stroke group). Patients who experienced a stroke postoperatively were divided into two groups based on the type of surgery: those who underwent surgery with cardiopulmonary bypass (18 patients) and those without cardiopulmonary bypass (30 patients). The clinical characteristics of the two groups of patients with postoperative strokes were compared, and the risk factors influencing the occurrence of postoperative stroke complications in cardiac surgery were analyzed. RESULTS ① Clinical findings: Cardiopulmonary bypass group had lower cortical infarction rates but higher large-area and bilateral infarction rates compared to the non-cardiopulmonary bypass group (p < 0.05). No significant gender, age, or infarction type differences were observed (p > 0.05). ② Univariate analysis: No significant differences were found in gender, smoking, alcohol, lipids, or glucose levels (p > 0.05). However, age, education, hypertension, diabetes, hypotension, and atrial fibrillation showed significant differences (p < 0.05). ③ Multivariate Logistic regression: Age, education, hypertension, diabetes, hypotension, and atrial fibrillation were independent risk factors for postoperative stroke complications (p < 0.05). CONCLUSION Cardiopulmonary bypass increases risk of large-area and bilateral strokes; non-bypass surgery associates with cortical strokes. Age, educational level, hypertension, diabetes, postoperative hypotension, and atrial fibrillation are all factors independently associated with the occurrence of postoperative cerebral infarctions in cardiac surgery. Early interventions may reduce postoperative strokes.

Abstract
BACKGROUND To develop a novel complexity evaluation system for mitral valve repair based on preoperative echocardiographic data and multiple machine learning algorithms. METHODS From March 2021 to March 2023, 231 consecutive patients underwent mitral valve repair. Clinical and echocardiographic data were included in the analysis. The end points included immediate mitral valve repair failure (mitral replacement secondary to mitral repair failure) and recurrence regurgitation (moderate or greater mitral regurgitation [MR] before discharge). Various machine learning algorithms were used to establish the complexity evaluation system. RESULTS A total of 231 patients were included in this study; the median ejection fraction was 66% (63-70%), and 159 (68.8%) patients were men. Mitral repair was successful in 90.9% (210 of 231) of patients. The linear support vector classification model has the best prediction results in training and test cohorts and the variables of age, A2 lesions, leaflet height, MR grades, and so on were risk factors for failure of mitral valve repair. CONCLUSION The linear support vector classification prediction model may allow the evaluation of the complexity of mitral valve repair. Age, A2 lesions, leaflet height, MR grades, and so on may be associated with mitral repair failure.

Abstract
OBJECTIVES Using the cardiac surgery database is of high importance in referral centers and can lead to a better quality of care for patients. Tehran Heart Center (THC) is a cardiovascular referral center that was inaugurated in 2001. In this report, we aimed to present the third report of trends in patients' cardiovascular risk factors and surgical procedures from 2002 to 2021 that have been gathered for all THC patients. METHODS This serial cross-sectional study was conducted at Tehran Heart Center from 2002 to 2021. All patients undergoing cardiac surgeries were eligible to enter the study (N = 63,974). Those with miscellaneous types of surgeries were excluded (N = 9556). The distribution of cardiac surgeries (including isolated coronary artery bypass graft (CABG), isolated valve, and CABG + valve surgeries) and their respective in-hospital mortality were recorded. Furthermore, 20-year trends in the prevalence of various cardiovascular risk factors (CVRFs) among the following groups were evaluated: a) isolated CABG, b) aortic valve replacement/repair for aortic stenosis (AS/AVR/r), and c) isolated other valve surgeries (IVS). RESULTS A total of 54,418 patients (male: 70.7%, age: 62.7 ± 10.8 years) comprised the final study population, with 84.5% prevalence of isolated CABG. Overall, the AS/AVR/r group was in between the CABG and IVS groups concerning CVRFs distribution. Excluding some exceptions for the AS/AVR/r group (in which the small sample size (N = 909) precluded observing a clear trend), all studied CVRFs demonstrated an overall rising trend from 2002 to 2021 in all three groups. Regarding in-hospital mortality, the highest rate was recorded as 4.0% in 2020, while the lowest rate was 2.0% in 2001. CONCLUSIONS Isolated CABG remained the most frequent procedure in THC. Notable, increasing trends in CVRFs were observed during this 20-year period and across various types of cardiac surgeries, which highlights the clinical and policy-making implications of our findings.

[PMID: 38008268 DOI: 10.1016/j.jvs.2023.11.032] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2023] [Revised: 11/17/2023] [Accepted: 11/19/2023] [Indexed: 11/28/2023]
Abstract
OBJECTIVE Since its inception in the early 2000s, hybrid arch repair (HAR) has evolved from novel approach to well-established treatment modality for aortic arch pathology in appropriately selected patients. Despite this nearly 20-year history of use, long-term results of HAR remain to be determined. As such, objectives of this study are to detail the long-term outcomes for HAR within an expanded classification scheme. METHODS From August 2005 to August 2022, 163 consecutive patients underwent HAR at a single referral institution. Operative approach was selected according to an institutional algorithm and included zone 0/1 HAR in 25% (n = 40), type I HAR in 34% (n = 56), and type II/III HAR in 41% (n = 67). Specific zone 0/1 technique was zone 1 HAR in 31 (78%), zone 0 with innominate snorkel (zone 0S HAR) in 7 (18%), and zone 0 with single side-branch endograft (zone 0B HAR) in 2 (5%). The 30-day and long-term outcomes, including overall and aortic-specific survival, as well as freedom from reintervention, were assessed. RESULTS The mean age was 63 ± 13 years and almost one-half of patients (47% [n = 77]) had prior sternotomy. Presenting pathology included degenerative aneurysm in 44% (n = 71), residual dissection after prior type A repair in 38% (n = 62), chronic type B dissection in 12% (n = 20), and other indications in 6% (n = 10). Operative outcomes included 9% mortality (n = 14) at 30 days, 5% mortality (n = 8) in hospital, 4% stroke (n = 7), 2% new dialysis (n = 3), and 2% permanent paraparesis/plegia (n = 3). The median follow-up was 44 month (interquartile range, 12-84 months). Overall survival was 59% and 47% at 5 and 10 years, respectively, whereas aorta-specific survival was 86% and 84% at the same time points. At 5 and 10 years, freedom from major reintervention was 92% and 91%, respectively. Institutional experience had a significant impact on both early and late outcomes: comparing the first (2005-2012) and second (2013-2022) halves of the series, 30-day mortality decreased from 14% to 1% (P = .01) and stroke from 6% to 3% (P = .62). Improved operative outcomes were accompanied by improved late survival, with 78% of patients in the later era vs 45% in the earlier era surviving to 5 years. CONCLUSIONS HAR is associated with excellent operative outcomes, as well as sustained protection from adverse aortic events as evidenced by high long-term aorta-specific survival and freedom from reintervention. However, surgeon and institutional experience appear to play a major role in achieving these superior outcomes, with a five-fold decrease in operative mortality and a two-fold decrease in stroke rate in the latter half of the series. These long-term results expand on prior midterm data and continue to support use of HAR for properly selected patients with arch disease.

Risk factors for surgical site infection following cardiac surgery in a region endemic for multidrug resistant organisms. Intensive Crit Care Nurs 2024; 81:103612.

Abstract
OBJECTIVES To identify risk factors for surgical site infections following cardiosurgery in an area endemic for multidrug resistant organisms. DESIGN Single-center, historical cohort study including patients who underwent cardiosurgery during a 6-year period (2014-2020). SETTING Joint Commission International accredited, multiorgan transplant center in Palermo, Italy. MAIN OUTCOME MEASURES Surgical site infection was the main outcome. RESULTS On a total of 3609 cardiosurgery patients, 184 developed surgical site infection (5.1 %). Intestinal colonization with multidrug resistant organisms was more frequent in patients with surgical site infections (69.6 % vs. 33.3 %; p < 0.001). About half of surgical site infections were caused by Gram-negative bacteria (n = 97; 52.7 %). Fifty surgical site infections were caused by multidrug resistant organisms (27.1 %), with extended-spectrum Beta-lactamase-producing Enterobacterales (n = 16; 8.7 %) and carbapenem-resistant Enterobacterales (n = 26; 14.1 %) being the predominant resistance problem. However, in only 24 of surgical site infections caused by multidrug resistant organisms (48 %), mostly carbapenem-resistant Enterobacterales (n = 22), a pathogen match between the rectal surveillance culture and surgical site infections clinical culture was demonstrated. Nevertheless, multivariate logistic regression analysis identified a rectal swab culture positive for multidrug resistant organisms as an independent risk factor for SSI (odds ratio 3.95, 95 % confidence interval 2.79-5.60). Other independent risk factors were female sex, chronic dialysis, diabetes mellitus, previous cardiosurgery, previous myocardial infarction, being overweight/obese, and longer intubation time. CONCLUSION In an area endemic for carbapenem-resistant Enterobacterales, intestinal colonization with multidrug resistant organisms was recognized as independent risk factor for surgical site infections. IMPLICATIONS FOR CLINICAL PRACTICE No causal relationship between colonization with resistant pathogens and subsequent infection could be demonstrated. However, from a broader epidemiological perspective, having a positive multidrug resistant organisms colonization status appeared a risk factor for surgical site infections. Therefore, strict infection control measures to prevent cross-transmission remain pivotal (e.g., nasal decolonization, hand hygiene, and skin antisepsis).

Abstract
MINI-ABSTRACT The study introduces various methods of performing conventional ML and their implementation in surgical areas, and the need to move beyond these traditional approaches given the advent of big data. OBJECTIVE Investigate current understanding and future directions of machine learning applications, such as risk stratification, clinical data analytics, and decision support, in surgical practice. SUMMARY BACKGROUND DATA The advent of the electronic health record, near unlimited computing, and open-source computational packages have created an environment for applying artificial intelligence, machine learning, and predictive analytic techniques to healthcare. The "hype" phase has passed, and algorithmic approaches are being developed for surgery patients through all stages of care, involving preoperative, intraoperative, and postoperative components. Surgeons must understand and critically evaluate the strengths and weaknesses of these methodologies. METHODS The current body of AI literature was reviewed, emphasizing on contemporary approaches important in the surgical realm. RESULTS AND CONCLUSIONS The unrealized impacts of AI on clinical surgery and its subspecialties are immense. As this technology continues to pervade surgical literature and clinical applications, knowledge of its inner workings and shortcomings is paramount in determining its appropriate implementation.

Abstract
The assessment of valvular pathologies in multiple valvular heart disease by echocardiography remains challenging. Data on echocardiographic assessment-especially in patients with combined aortic and mitral regurgitation-are rare in the literature. The proposed integrative approach using semi-quantitative parameters to grade the severity of regurgitation often yields inconsistent findings and results in misinterpretation. Therefore, this proposal aims to focus on a practical systematic echocardiographic analysis to understand the pathophysiology and hemodynamics in patients with combined aortic and mitral regurgitation. The quantitative approach of grading the regurgitant severity of each compound might be helpful in elucidating the scenario in combined aortic and mitral regurgitation. To this end, both the individual regurgitant fraction of each valve and the total regurgitant fraction of both valves must be determined. This work also outlines the methodological issues and limitations of the quantitative approach by echocardiography. Finally, we present a proposal that enables verifiable assessment of regurgitant fractions. The overall interpretation of echocardiographic results includes the symptomatology of patients with combined aortic and mitral regurgitation and the individual treatment options with respect to their individual risk. In summary, a reproducible, verifiable, and transparent in-depth echocardiographic investigation might ensure consistent hemodynamic plausibility of the quantitative results in patients with combined aortic and mitral regurgitation.

Abstract
Purpose This study aims to evaluate the perioperative outcomes of aortic valve replacement (AVR) via right anterior minithoracotomy (RAT) during the learning curve. Methods It was a retrospective, observational, cohort study of patients who underwent RAT AVR from June 2015 to April 2022. Primary outcomes measured were 30-day morbidity and mortality. Results A total of 107 consecutive patients underwent elective RAT AVR. Our patients were mostly male (78.5%), elderly (mean 68.7 years), and obese (34.6%). A majority of the patients (93.5%) were of low operative risk. Median cross-clamp and bypass times were 95 and 123 minutes respectively. There was a statistically significant correlation between increase in number of cases and decrease in operative time. All patients had no paravalvular leak at discharge. There were no operative cardiovascular mortality or major morbidity including stroke, myocardial infarction, renal failure requiring dialysis, or vascular complication. No patient required intraoperative conversion to full sternotomy for completion of AVR. Conclusion Our study demonstrated that RAT AVR can be safely introduced. The learning curve required in performing RAT AVR can be safely negotiated through training, previous experience in minimally invasive surgery, careful patient selection including use of preoperative computed tomography of the aorta, and introduction of sutureless/rapid deployment valves.

Abstract
Surgeons and anesthesia clinicians commonly face a hemodynamic disturbance known as intraoperative hypotension (IOH), which has been linked to more severe postoperative outcomes and increases mortality rates. Increased occurrence of IOH has been positively associated with mortality and incidence of myocardial infarction, stroke, and organ dysfunction hypertension. Hence, early detection and recognition of IOH is meaningful for perioperative management. Currently, when hypotension occurs, clinicians use vasopressor or fluid therapy to intervene as IOH develops but interventions should be taken before hypotension occurs; therefore, the Hypotension Prediction Index (HPI) method can be used to help clinicians further react to the IOH process. This literature review evaluates the HPI method, which can reliably predict hypotension several minutes before a hypotensive event and is beneficial for patients' outcomes.

Abstract
BACKGROUND Little is known about hospital pricing for coronary artery bypass grafting (CABG). Using new price transparency data, we assessed variation in CABG prices across US hospitals and the association between higher prices and hospital characteristics, including quality of care. METHODS AND RESULTS Prices for diagnosis related group code 236 were obtained from the Turquoise database and linked by Medicare Facility ID to publicly available hospital characteristics. Univariate and multivariable analyses were performed to assess factors predictive of higher prices. Across 544 hospitals, median commercial and self-pay rates were 2.01 and 2.64 times the Medicare rate ($57 240 and $75 047, respectively, versus $28 398). Within hospitals, the 90th percentile insurer-negotiated price was 1.83 times the 10th percentile price. Across hospitals, the 90th percentile commercial rate was 2.91 times the 10th percentile hospital rate. Regional median hospital prices ranged from $35 624 in the East South Central to $84 080 in the Pacific. In univariate analysis, higher inpatient revenue, greater annual discharges, and major teaching status were significantly associated with higher prices. In multivariable analysis, major teaching and investor-owned status were associated with significantly higher prices (+$8653 and +$12 200, respectively). CABG prices were not related to death, readmissions, patient ratings, or overall Centers for Medicare and Medicaid Services hospital rating. CONCLUSIONS There is significant variation in CABG pricing, with certain characteristics associated with higher rates, including major teaching status and investor ownership. Notably, higher CABG prices were not associated with better-quality care, suggesting a need for further investigation into drivers of pricing variation and the implications for health care spending and access.

Abstract
BACKGROUND The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs). METHODS The AHA, through its Epidemiology and Prevention Statistics Committee, continuously monitors and evaluates sources of data on heart disease and stroke in the United States and globally to provide the most current information available in the annual Statistical Update with review of published literature through the year before writing. The 2024 AHA Statistical Update is the product of a full year's worth of effort in 2023 by dedicated volunteer clinicians and scientists, committed government professionals, and AHA staff members. The AHA strives to further understand and help heal health problems inflicted by structural racism, a public health crisis that can significantly damage physical and mental health and perpetuate disparities in access to health care, education, income, housing, and several other factors vital to healthy lives. This year's edition includes additional global data, as well as data on the monitoring and benefits of cardiovascular health in the population, with an enhanced focus on health equity across several key domains. RESULTS Each of the chapters in the Statistical Update focuses on a different topic related to heart disease and stroke statistics. CONCLUSIONS The Statistical Update represents a critical resource for the lay public, policymakers, media professionals, clinicians, health care administrators, researchers, health advocates, and others seeking the best available data on these factors and conditions.

Efficacy of Single-Bolus Administration of Remimazolam During Induction of Anesthesia in Patients Undergoing Cardiac Surgery: A Prospective, Single-Center, Randomized Controlled Study. Anesth Analg 2024:00000539-990000000-00732.

Abstract
BACKGROUND Remimazolam is a recently marketed ultrashort-acting benzodiazepine. This drug is considered safe and effective during general anesthesia; however, limited information is available about its effects on patients undergoing cardiac surgery. Therefore, the present study was conducted to evaluate the efficacy and hemodynamic stability of a bolus administration of remimazolam during anesthesia induction in patients undergoing cardiac surgery. METHODS Patients undergoing elective cardiac surgery were randomly assigned to any 1 of the following 3 groups: anesthesia induction with a continuous infusion of remimazolam 6 mg/kg/h (continuous group), a single-bolus injection of remimazolam 0.1 mg/kg (bolus 0.1 group), or a single-bolus injection of remimazolam 0.2 mg/kg (bolus 0.2 group). Time to loss of responsiveness, defined as modified Observer's Assessment of Alertness/Sedation Scale <3, and changes in hemodynamic status during anesthetic induction were measured. RESULTS Times to loss of responsiveness were 137 ± 20, 71 ± 35, and 48 ± 9 seconds in the continuous, bolus 0.1, and bolus 0.2 groups, respectively. The greatest mean difference was observed between the continuous and bolus 0.2 groups (89.0, 95% confidence interval [CI], 79.1-98.9), followed by the continuous and bolus 0.1 groups (65.8, 95% CI, 46.9-84.7), and lastly between the bolus 0.2 and bolus 0.1 groups (23.2, 95% CI, 6.6-39.8). No significant differences were found in terms of arterial blood pressures and heart rates of the patients. CONCLUSIONS A single-bolus injection of remimazolam provided efficient anesthetic induction in patients undergoing cardiac surgery. A 0.2 mg/kg bolus injection of remimazolam resulted in the shortest time to loss of responsiveness among the 3 groups, without significantly altering the hemodynamic parameters. Therefore, this dosing can be considered a favorable anesthetic induction method for patients undergoing cardiac surgery.

J Cardiothorac Vasc Anesth 2024; 38:394-402.

Abstract
OBJECTIVES Patients undergoing cardiac surgery often require blood transfusions, which are associated with increased morbidity and mortality. Patient blood management (PBM) strategies, including acute normovolemic hemodilution (ANH), have been implemented to minimize allogeneic transfusion requirements. Older studies suggested that ANH is associated with reduced transfusions; however, its effectiveness in the modern era of PBM remains unclear. DESIGN This was a retrospective cohort study. SETTING The study was held at a single university hospital. PARTICIPANTS 542 patients who underwent elective cardiac surgery with cardiopulmonary bypass (CPB) using low-priming-volume circuits between January 2017 and March 2022. INTERVENTIONS Patients who received ANH were matched with those who did not receive ANH, using propensity scores. MEASUREMENTS AND MAIN RESULTS The primary outcome was the proportion of patients who received perioperative red blood cell (RBC) transfusion. Of the 542 eligible patients, 49 ANH cases were propensity-score matched to 97 controls. The median ANH volume was 450 mL (IQR, 400-800 mL). There was no significant difference in perioperative RBC transfusion rates between the 2 groups (24.5% in the ANH group vs 30.9% in the control group, p = 0.42). The odds ratio for perioperative RBC transfusion in the ANH group versus the control group was 0.72 (95% CI, 0.32-1.55, p = 0.42). CONCLUSIONS Low-volume ANH was not associated with a significant reduction in perioperative allogeneic RBC transfusion during cardiac surgery with CPB using low-priming-volume circuits. The benefits of low-volume ANH in reducing the requirement for RBC transfusion in the modern era of PBM may be smaller than reported previously.

Abstract
INTRODUCTION Socioeconomic disparities impact outcomes after cardiac surgery. At our institution, cardiac surgery cases from the safety-net, county funded hospital (CH), which primarily provides care for underserved patients, are performed at the affiliated university hospital. We aimed to investigate the association of socioeconomic factors and CH referral status with outcomes after coronary artery bypass grafting (CABG). METHODS The institutional Adult Cardiac Surgery database was queried for perioperative and demographic data from patients who underwent isolated CABG between January 2014 and June 2020. The primary outcome was major adverse cardiovascular event (MACE), a composite of postoperative myocardial infarction, stroke, or death. Secondary outcomes included individual complications. Chi-square, Wilcoxon rank-sum, and logistic regression analyses were used to compare differences between CH and non-CH cohorts. RESULTS We included 836 patients with 472 (56.5%) from CH. Compared to the non-CH cohort, CH patients were younger, more likely to be Hispanic, non-English speaking, and be completely uninsured or require state-specific financial assistance. CH patients were more likely to have a history of tobacco and drug use, liver disease, diabetes, prior myocardial infarction, and greater degrees of left main coronary and left anterior descending artery stenosis. CH cases were less likely to be elective. The incidence of MACE was significantly higher in the CH cohort (16.3% versus 8.2%, P = 0.001). There were no significant differences in 30-d mortality, home discharge, prolonged mechanical ventilation, bleeding, sepsis, pneumonia, new dialysis requirement, cardiac arrest, or multiorgan system failure between cohorts. CH patients were more likely to develop renal failure and less likely to develop atrial fibrillation. On multivariable analysis, CH status (odds ratio 2.39, 95% confidence interval 1.25-4.55, P = 0.008) was independently associated with MACE. CONCLUSIONS CH patients undergoing CABG presented with greater comorbidity burden, more frequently required nonelective surgery, and are at significantly higher risk of postoperative MACE.

Abstract
INTRODUCTION To examine risk factors for new-onset postoperative atrial fibrillation (POAF) after cardiac surgery. METHODS Patients enrolled in the Cardiothoracic Surgical Trials Network multicenter, randomized trial of rate control versus rhythm control for POAF were included. Predictors of POAF were determined using multivariable logistic regression. RESULTS Among the 2104 patients who were enrolled preoperatively, 695 developed POAF (33.0%). Rates of POAF were 28.1% after isolated coronary artery bypass grafting (CABG), 33.7% after isolated valve repair or replacement, and 47.3% after CABG plus valve repair or replacement. Baseline characteristics associated with an increased risk of POAF identified on multivariable analysis included older age (odds ratio [OR] 1.57; 95% confidence interval [CI] 1.42-1.73, per 10 y), White race or non-Hispanic ethnicity (OR 1.52; CI: 1.11-2.07), history of heart failure (OR 1.55; CI: 1.16-2.08), and history of hypothyroidism (OR 1.42; CI 1.04-1.94). The type of cardiac procedure was associated with an increased risk of POAF with both isolated valve repair or replacement (OR 1.33, CI 1.08-1.64) and combined CABG plus valve repair or replacement (OR 1.64, CI 1.24-2.17) having increased risk of POAF compared to isolated CABG. No preoperative cardiac medication was associated with POAF. CONCLUSIONS In this prospective cohort of patients, older age, a history of hypothyroidism, a history of heart failure, and valve repair or replacement, with or without CABG, and White non-Hispanic race were associated with an increased risk of POAF.

Abstract
BACKGROUND The Society of Thoracic Surgeons (STS) National Databases contain the largest and most comprehensive cardiac, thoracic, and congenital surgery data available. In this analysis characteristics of manuscripts that used the STS National Databases were examined to evaluate the quality and impact of these publications. METHODS Manuscripts published from 2010 to 2020 that used the STS National Databases (Adult Cardiac, General Thoracic, and Congenital Heart Surgery) were examined. The number of times cited per published manuscript, journal of publication, and journal CiteScore were assessed. Author characteristics, including institutional association and h-index, were evaluated for first and last authors. RESULTS Of 539 published manuscripts, 179 (33.2%) used the Adult Cardiac Surgery, 128 (23.7%) the Congenital Heart Surgery, 85 (15.8%) the General Thoracic Surgery, and 136 (25.2%) used unspecified STS National Databases. Collectively the analyzed manuscripts were cited 18,943 times, with a mean of 35.1 (range, 0-528) citations per manuscript. Manuscripts were published in 97 journals with a mean year-adjusted CiteScore of 5.6 (range, 0.1-60.2). Authors associated with 361 institutions contributed to published manuscripts. The mean h-index of first authors was 24.6 (range, 0-100) and of last authors was 44.1 (range, 0-164). From 2010 to 2020 first authors wrote a mean of 1.6 (range, 1-31) and last authors wrote a mean of 1.9 (range, 1-29) STS National Databases publications. CONCLUSIONS The STS National Databases are some of the most robust data collection sources available to cardiothoracic surgeons. These data have enabled valuable research in respected journals from authors of varying experience levels.

Abstract
Patients with end-stage kidney disease (ESKD) on dialysis have an increased burden of coronary artery disease (CAD). This study assessed the trend and outcomes for coronary artery bypass surgery (CABG) in patients with ESKD and stable CAD. We conducted a longitudinal study using the United States Renal Data System of patients with ESKD and stable CAD who underwent CABG from the years 2009 to 2017. The outcomes included in-hospital, long-term mortality, and repeat revascularization. The follow-up was until death, end of Medicare AB coverage, or December 31, 2018. A total of 11,952 patients were identified. The mean age was 62.8 years, 68% were male, and 67% were white. The common co-morbidities included hypertension (97%), diabetes mellitus (75%), and congestive heart failure (53%). A significant decrease in CABG procedures from 2.9 to 1.3 procedures per 1,000 patients with ESKD (p <0.001) was noted during the years studied. The overall in-hospital mortality rate was 5.9%, and there was a significant decrease over the study period (p = 0.01). Although the 30-day mortality rate was 6.9% and remained steady (p = 0.14), the 1-year mortality rate was 22.8% and decreased significantly (p <0.001). At 5 years, the overall survival rate was 35%, and patients with internal mammary artery grafts showed better survival than those without (36% vs 25%). In conclusion, there has been a decrease in CABG procedures performed in patients with ESKD with stable CAD with decreasing in-hospital and 1-year mortality. Those with an internal mammary artery graft do better, but the overall long-term survival remains dismal in this population. There remains need for caution and individualization of revascularization decisions in this high-risk population.

[PMID: 37858882 DOI: 10.1016/j.athoracsur.2023.10.006] [Citation(s) in RCA: 19] [Impact Index Per Article: 19.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/29/2023] [Revised: 10/11/2023] [Accepted: 10/11/2023] [Indexed: 10/21/2023]
Abstract
BACKGROUND The use of transcatheter aortic valve replacement for severe aortic stenosis in low-risk patients necessitates an evaluation of contemporary long-term, real-world outcomes of similar patients undergoing surgical aortic valve replacement (SAVR) in a national cohort. METHODS All patients undergoing primary, isolated SAVR in The Society of Thoracic Surgeons (STS) database between 2011 and 2019 were examined. The study population of 42,586 adhered to the inclusion/exclusion criteria of the Placement of Aortic Transcatheter Valves (PARTNER) 3 and Evolut Low Risk randomized trials. Patients were further stratified by STS predicted risk of mortality (PROM), age, and left ventricular ejection fraction. The primary end-point was all-cause National Death Index mortality. Unadjusted survival to 8 years was estimated using the Kaplan-Meier method. RESULTS Mean age was 74.3 ± 5.7 years and mean STS PROM was 1.9% ± 0.8%. The overall Kaplan-Meier time to event analysis for all-cause mortality at 1, 3, 5, and 8 years was 2.6%, 4.5%, 7.1%, and 12.4%, respectively. In subset analyses, survival was significantly better for (1) lower STS PROM (P < .001), (2) younger vs older age (P < .001), and (3) higher vs lower left ventricular ejection fraction (P < .001). When STS PROM was below 1% or the patient age was below age 75 years, the 8-year survival after SAVR was 95%. CONCLUSIONS The results of this national study confirm that long-term survival after SAVR remains excellent, at 92.9% at 5 years. These contemporary longitudinal data serve to aid in the balanced interpretation of current and future trials comparing SAVR and transcatheter aortic valve replacement and may assist in the clinical decision-making process for patients of lower surgical risk.

Influence of concomitant ablation of nonparoxysmal atrial fibrillation during coronary artery bypass grafting on mortality and readmissions. JTCVS OPEN 2023; 16:355-369. [PMID: 38204710 PMCID: PMC10775120 DOI: 10.1016/j.xjon.2023.09.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/03/2023] [Revised: 09/11/2023] [Accepted: 09/14/2023] [Indexed: 01/12/2024]
Abstract
Objective We determined the utilization rate of surgical ablation (SA) during coronary artery bypass grafting (CABG) and compared outcomes between CABG with or without SA in a national cohort. Methods The January 2016 to December 2018 Nationwide Readmissions Database was searched for all patients undergoing isolated CABG with preoperative persistent or chronic atrial fibrillation by using the International Classification of Diseases, 10th Revision classification. Propensity score matching and multivariate logistic regressions were performed to compare outcomes, and Cox proportional hazards model was used to assess risk factors for 1-year readmission. Results Of 18,899 patients undergoing CABG with nonparoxysmal atrial fibrillation, 78% (n = 14,776) underwent CABG alone and 22% (n = 4123) underwent CABG with SA. In the propensity score-matched cohort (n = 8116), CABG with SA (n = 4054) (vs CABG alone [n = 4112]) was not associated with increased in-hospital mortality (3.4% [139 out of 4112] vs 3.9% [159 ut of 4054]; P = .4), index-hospitalization length of stay (10 days vs 10 days; P = .3), 30-day readmission (19.1% [693 out of 3362] vs 17.2% [609 out of 3537]; P = .2), or 90-day readmission (28.9% [840 out of 2911] vs 26.2% [752 out of 2875]; P = .1). Index hospitalization costs were significantly higher for those undergoing SA ($52,556 vs $47,433; P < .001). Rates of readmission at 300 days were similar between patients receiving SA (43.8%) and no SA (42.8%; log-rank P = .3). The 3 most common causes of readmission were not different between groups and included heart failure (24.3% [594 out of 2444]; P = .6), infection (16.8% [411 out of 2444]; P = .5), and arrhythmia (11.7% [286 out of 2444]; P = .2). Conclusions In patients with nonparoxysmal atrial fibrillation, utilization of SA during CABG remains low. SA during CABG did not adversely influence mortality or short-term readmissions. These findings support increased use of SA during CABG.

Abstract
BACKGROUND The clinical applicability of machine learning predictions of patient outcomes following cardiac surgery remains unclear. We applied machine learning to predict patient outcomes associated with high morbidity and mortality after cardiac surgery and identified the importance of variables to the derived model's performance. METHODS We applied machine learning to the Society of Thoracic Surgeons Adult Cardiac Surgery Database to predict postoperative hemorrhage requiring reoperation, venous thromboembolism (VTE), and stroke. We used permutation feature importance to identify variables important to model performance and a misclassification analysis to study the limitations of the model. RESULTS The study dataset included 662,772 subjects who underwent cardiac surgery between 2015 and 2017 and 240 variables. Hemorrhage requiring reoperation, VTE, and stroke occurred in 2.9%, 1.2%, and 2.0% of subjects, respectively. The model performed remarkably well at predicting all 3 complications (area under the receiver operating characteristic curve, 0.92-0.97). Preoperative and intraoperative variables were not important to model performance; instead, performance for the prediction of all 3 outcomes was driven primarily by several postoperative variables, including known risk factors for the complications, such as mechanical ventilation and new onset of postoperative arrhythmias. Many of the postoperative variables important to model performance also increased the risk of subject misclassification, indicating internal validity. CONCLUSIONS A machine learning model accurately and reliably predicts patient outcomes following cardiac surgery. Postoperative, as opposed to preoperative or intraoperative variables, are important to model performance. Interventions targeting this period, including minimizing the duration of mechanical ventilation and early treatment of new-onset postoperative arrhythmias, may help lower the risk of these complications.

Abstract
Study objective Examine sex-specific characteristics in patients undergoing coronary artery bypass grafting (CABG) at our institution. Design Retrospective chart review was performed utilizing our institutional Society of Thoracic Surgeons (STS) database. Setting An academic, quaternary care center from 2010 to 2021. Participants 3163 females and 9573 males underwent isolated CABG. Interventions The institutional STS database was queried for preoperative, intraoperative, and postoperative variables. Main outcome measures Univariate comparisons between female and male groups were performed using chi-squared tests or fisher exact tests. Multivariate logistic regression was used to assess risk factors for 30-day mortality. Results Females had more preoperative comorbidities than males, including hypertension, diabetes, peripheral arterial disease, cerebrovascular disease, renal failure, and prior myocardial infarction. Females more frequently underwent urgent (61 % vs. 58 %) or emergent CABG (5.8 % vs. 4.3 %) compared to males (p < 0.0001). Females experienced longer total intensive care unit (ICU) hours (48.3 h vs. 43.5 h) (p < 0.0001), were more frequently discharged to an extended care facility (13 % vs. 6.4 %) (p < 0.0001) and prescribed less aspirin and beta blocker therapy at discharge than males. In-hospital mortality was higher in females (1.9 % vs. 1.2 %, p = 0.002), as was 30-day mortality (2.7 % vs. 1.6 %, p = 0.0001). Female sex was an independent risk factor for 30-day mortality (odds ratio = 1.46, 95 % CI: 1.06, 2.03, p = 0.02). Conclusion Over the past decade, females undergoing CABG had more preoperative comorbidities, urgent and emergent operations, longer postoperative ICU stay and a higher risk of mortality than their male counterparts. Further studies must investigate these disparities to improve outcomes for females undergoing CABG.

Abstract
OBJECTIVES Older studies of coronary artery bypass grafting (CABG) institutional case volumes and outcomes reported conflicting results. We explored this association in the rapidly changing contemporary practice of American surgeons using the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database. METHODS The 2018-2019 isolated primary CABG experience in the STS Adult Cardiac Surgery Database was analysed (241 902 patients; 1014 hospitals; 2718 surgeons). Generalized Estimating Equations were used to estimate coefficients between CABG institutional case volumes and outcomes. The observed-to-expected ratios based on STS risk models were used to assess risk-adjusted operative mortality (OM), mortality/major morbidity (MM) and deep sternal wound infections (DSWI) as a function of institutional case volumes. RESULTS The mean (standard deviation) OM, MM and DSWI rates were 2.1% (2.7), 11.1% (9.2) and 0.6% (0.5), respectively. The mean (standard deviation) institutional case volumes per study period was 239 (192); 23% and 9% of institutions performed <100 and >500 cases/study period, respectively. There was a weak negative correlation between expected mortality (R2 -0.0014), OM (R2 -0.0272), MM (R2 -0.1213) and DSWI (R2 -0.003) and institutional case volumes. CONCLUSIONS CABG outcomes generally improve with increasing institutional case volumes. Given the large number of CABG cases performed nationally, even the documented weak correlation has the potential to appreciably decrease OM, MM and DSWI if cases are performed at higher volume institutions. Studies focusing on additional hospital and surgeon factors are warranted to further define quality improvement opportunities.

[PMID: 37741752 DOI: 10.1016/j.hlc.2023.08.005] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2023] [Revised: 06/25/2023] [Accepted: 08/04/2023] [Indexed: 09/25/2023]
Abstract
OBJECTIVE To determine whether primary percutaneous coronary intervention (PPCI) is associated with adverse outcomes following coronary artery bypass graft (CABG) among patients with ST-elevation myocardial infarction (STEMI). METHODS Patients presenting with acute STEMI who underwent CABG between September 2015 and November 2020 were included. Among 354 patients, 222 (62.7%) underwent PPCI prior to CABG (PPCI+CABG group) and were compared with the rest of the patients (CABG only group). The effects of PPCI on primary endpoints---including in-hospital mortality, length of stay (LOS), and bleeding events---were investigated using the stabilised inverse probability weighting method (S-IPW). Further, in-hospital mortality in various PPCI subgroups was analysed using univariable regression. RESULTS Patients with and without PPCI were comparable regarding their baseline and surgical characteristics, except that those without PPCI were more likely to have left-main disease (29.5% vs 16.2%, p-value=0.003). Among the PPCI+CABG group, 3.6% mortality and 55.9% bleeding events occurred, and the LOS was 7 [5-10] days. The respective figures for the CABG only group were 4.5%, 50.8%, and 7 [6-10.5] days. Primary percutaneous coronary intervention, as a whole, was not significantly associated with either morality (S-IPW odds ratio (S-IPW OR) 0.61; p=0.393), LOS logarithm (S-IPW β -0.050; p=0.403), or bleeding events (S-IPW OR 1.06; p=0.821). Nevertheless, the unadjusted mortality risk was significantly higher in complicated PPCIs compared with the CABG only group (OR 7.50, 95% CI 2.03-27.77); it was also higher among some other PPCI subgroups, albeit non-significantly. CONCLUSION This study found that PPCI did not confer additional risk regarding in-hospital mortality, LOS, or bleeding among patients with acute STEMI who underwent CABG. However, some PPCI subgroups, especially those with complicated PPCI, were at increased risk.

Abstract
BACKGROUND Given the uncertainty of US health care finances, an understanding of reimbursement trends has become increasingly important in the field of cardiac surgery. We aimed to assess Medicare reimbursement trends for common cardiac surgical procedures from 2000 to 2022. METHODS Reimbursement data were extracted from the Centers for Medicare and Medicaid Services Physician Fee Schedule Look-Up Tool during the study period for 6 common cardiac operations: aortic valve replacement, mitral valve repair and replacement, tricuspid valve replacement, Bentall procedure, and coronary artery bypass grafting. Reimbursement rates were adjusted for inflation to 2022 US dollars using the Consumer Price Index. Total percentage change and compound annual growth rate were calculated. A split-time analysis was performed to assess trends before and after 2015. Least squares and linear regressions were performed. The R2 value was calculated for each procedure, and slope was used to determine change in reimbursements over time. RESULTS Inflation-adjusted reimbursement decreased by 34.1% during the study period. The overall compound annual growth rate was -1.8%. Reimbursement trends differed by procedure (P < .001), with all reimbursements trending down (R2 > 0.62), except for mitral valve replacement (P = .21) and tricuspid valve replacement (P = .43). Coronary artery bypass grafting decreased the most (-44.4%), followed by aortic valve replacement (-40.1%), mitral valve repair (-38.5%), mitral valve replacement (-29.8%), Bentall procedure (-28.5%), and tricuspid valve replacement (-25.3%). In split-time analysis, reimbursement rates did not significantly change from 2000 to 2015 (P = .24) but decreased significantly from 2016 to 2022 (P = .001). CONCLUSIONS Medicare reimbursement significantly decreased for most cardiac surgical procedures. These trends justify further advocacy by The Society of Thoracic Surgeons to maintain access to quality cardiac surgical care.

Abstract
BACKGROUND The benefits of mitral valve repair vs replacement are well documented. However, survival benefits in the elderly population are more controversial. In this novel lifetime analysis, we hypothesize that survival benefits for valve repair vs replacement in the elderly are sustained throughout the patient's lifetime. METHODS From January 1985 through December 2005, 663 patients, aged ≥65 years with myxomatous degenerative mitral valve disease underwent primary isolated mitral valve repair (n = 434) or replacement (n = 229). Propensity score matching was used to balance variables potentially related to outcome. RESULTS Follow-up was complete in 99.1% of mitral repair and 99.6% of mitral replacement patients. In matched patients, perioperative mortality was 3.9% (9 of 229) for repair and 10.9% (25 of 229) for replacement (P = .004). Survival estimates (95% confidence limits) from 29-year follow-up for matched patients were 54.6% (48.0%, 61.1%) and 11.0% (6.8%, 15.2%) at 10 years and 20 years for repair patients, and 34.2% (27.7%, 40.7%) and 3.7% (1%, 6.4%) for replacement patients, respectively. Median survival (95% confidence limits) was 11.3 years (9.6, 12.2 years) for repair patients compared with 6.9 years (6.3, 8.0 years) for replacement patients (P < .001). CONCLUSIONS This study demonstrates that although the elderly population is prone to multiple comorbidities, survival benefits of isolated mitral valve repair vs replacement are sustained throughout the patient's lifetime.

Abstract
Atrial fibrillation is associated with an increased risk of stroke secondary to thrombus formation in the left atrial appendage. Left atrial appendage occlusion (LAAO) is an effective method of reducing the risk of stroke in patients with atrial fibrillation. Although LAAO does not remove the requirement for anticoagulation, it reduces the risk of stroke when compared to anticoagulation alone. We critically analyze the data on LAAO in cardiac surgery. We also discuss the methods of LAAO, the risks of LAAO, and patient populations that could benefit from LAAO. We discuss high-level evidence that LAAO at the time of cardiac surgery reduces the risk of stroke in patients with a history of atrial fibrillation. In patients without a history of atrial fibrillation undergoing cardiac surgery, we suggest that LAAO should be considered in select patients at high risk of atrial fibrillation and stroke, when technically feasible.

Abstract
OBJECTIVE Postoperative atrial fibrillation (POAF) is common after cardiac surgery and is often considered to be benign despite recent data suggesting worse outcomes. There are no guidelines for the amount of POAF that triggers anticoagulation or for postoperative surveillance. We examined the rate of POAF, incidence of neurologic events, development of permanent atrial fibrillation, and mortality in patients undergoing isolated mitral valve surgery at a Mitral Foundation reference center. METHODS This is a retrospective cohort study of 922 adult patients from 2011 to 2022 with no preoperative history of arrhythmias. Multivariable logistic regression was used to identify independent risk factors for the primary outcomes. Kaplan-Meier analysis and Cox proportional-hazards model were used to characterize long-term survival. RESULTS The incidence of POAF was 39%. Median follow-up was 4.9 months (interquartile range, 1.1-42.6 months). Diabetes (odds ratio [OR], 2.2; 95% CI, 1.2-4.1; P = .01) and increasing age (OR, 1.1; 95% CI, 1.0-1.1; P < .001) were risk factors for POAF, whereas New York Heart Association functional class was not. POAF was a risk factor for the development of permanent atrial fibrillation (OR, 3.2; 95% CI 1.9-5.4; P < .001), which was associated with increased risk of neurologic events (OR, 3.8; 95% CI, 1.5-9.7; P = .004). Ultimately, patients with POAF had worse unadjusted (P < .001) and adjusted long-term mortality (hazard ratio, 1.8; 95% CI, 1.1-3.1; P = .03). CONCLUSIONS POAF is associated with an increased rate of neurologic events, portends development of permanent atrial fibrillation, and is associated with worse long-term survival. POAF is not benign and carries a long-term mortality implication.

Abstract
Objective Clinical prediction models for surgical aortic valve replacement mortality, are valuable decision tools but are often limited in their ability to account for changes in medical practice, patient selection, and the risk of outcomes over time. Recent research has identified methods to update models as new data accrue, but their effect on model performance has not been rigorously tested. Methods The study population included 44,546 adults who underwent an isolated surgical aortic valve replacement from January 1, 1999, to December 31, 2018, statewide in Pennsylvania. After chronologically splitting the data into training and validation sets, we compared calibration, discrimination, and accuracy measures amongst a nonupdating model to 2 methods of model updating: calibration regression and the novel dynamic logistic state space model. Results The risk of mortality decreased significantly during the validation period (P < .01) and the nonupdating model demonstrated poor calibration and reduced accuracy over time. Both updating models maintained better calibration (Hosmer-Lemeshow χ2 statistic) than the nonupdating model: nonupdating (156.5), calibration regression (4.9), and dynamic logistic state space model (8.0). Overall accuracy (Brier score) was consistently better across both updating models: dynamic logistic state space model (0.0252), calibration regression (0.0253), and nonupdating (0.0256). Discrimination improved with the dynamic logistic state space model (area under the curve, 0.696) compared with the nonupdating model (area under the curve, 0.685) and calibration regression method (area under the curve, 0.687). Conclusions Dynamic model updating can improve model accuracy, discrimination, and calibration. The decision as to which method to use may depend on which measure is most important in each clinical context. Because competing therapies have emerged for valve replacement models, updating may guide clinical decision making.

Generalizability of an EHR-network dataset to the United States for cardiovascular disease conditions: Comparison of Cerner real world data with the national inpatient sample.

[PMID: 37196972 DOI: 10.1016/j.ahj.2023.05.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Revised: 05/04/2023] [Accepted: 05/11/2023] [Indexed: 05/19/2023]
Abstract
BACKGROUND Electronic Health Record (EHR) data from health systems are increasingly being combined for clinical research purposes. Yet, it remains unclear whether these large EHR data sources provide a representative assessment of national disease prevalence and treatment. To evaluate this, we compared Cerner RealWorldData (CRWD), a large EHR data source, to those seen in the National Inpatient Sample (NIS) for 3 cardiovascular conditions (myocardial infarction (MI), congestive heart failure (CHF), and stroke. METHODS Adult patients (age ≥18 years) hospitalized with MI, CHF, and stroke were identified in both CRWD (86 health systems) and the NIS (4,782 hospitals). Patient demographics, comorbidities, procedures, outcomes (length of stay and in-hospital mortality) and hospital type (teaching or nonteaching) were compared between NIS and CRWD patients. RESULTS Of 86 health systems participating in CRWD, 33 were excluded for potential data quality issues which accounted for about 11% of hospitalizations in the dataset, leaving 53 for inclusion in analysis which accounted for about 89% of hospitalizations in the dataset. Between January 1, 2017 and December 31, 2018, 116,956 MI, 188,107 CHF, and 93,968 stroke hospitalizations were identified in CRWD vs 2,245,300 MI, 4,310,745 CHF, and 1,333,480 stroke hospitalizations in the NIS. Patient demographics were similar among patients in CWRD and the NIS for all 3 cardiovascular groups except for ethnicity, with underrepresentation of Hispanic individuals in CRWD vs the NIS. Patients hospitalized in CRWD had a slightly higher proportion of coded co-morbidities compared with NIS hospitalizations due to a longer potential look-back period. For patients with MI, hospital mortality, length of stay, coronary artery bypass graft (CABG) rates, and percutaneous coronary intervention (PCI) rates were similar between CRWD and NIS. Additionally, there was similar in hospital mortality and length of stay for those with CHF and stroke hospitalizations between CRWD and NIS. CONCLUSIONS On aggregate, characteristics of hospitalizations for MI, CHF, and stroke using EHR data from one nationwide EHR-derived database, CRWD, appears similar to characteristics of hospitalizations in the nationally representative NIS. Important limitations of CRWD include lack of geographic representativeness, under-representation of Hispanic adults, and the need to exclude health systems for missing data.
