Efficacy and safety of edoxaban in patients early after surgical bioprosthetic valve implantation or valve repair: A randomized clinical trial. J Thorac Cardiovasc Surg 2023; 165:58-67.e4. [PMID: 33726903 DOI: 10.1016/j.jtcvs.2021.01.127] [Citation(s) in RCA: 30] [Impact Index Per Article: 30.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2020] [Revised: 01/28/2021] [Accepted: 01/28/2021] [Indexed: 12/16/2022]
Abstract
OBJECTIVE Early warfarin anticoagulation is recommended in patients undergoing surgical bioprosthetic valve implantation or valve repair. It is unclear whether non-vitamin K antagonist oral anticoagulants can be a full alternative to warfarin. This study aimed to compare efficacy and safety of edoxaban with warfarin in patients early after surgical bioprosthetic valve implantation or valve repair. METHODS The Explore the Efficacy and Safety of Edoxaban in Patients after Heart Valve Repair or Bioprosthetic Valve Replacement study was a prospective, randomized (1:1), open-label, clinical trial conducted from December 2017 to September 2019. Patients were randomly assigned to receive edoxaban (60 mg or 30 mg once daily) or warfarin for the first 3 months after surgical bioprosthetic valve implantation or valve repair. The primary efficacy outcome was a composite of death, clinical thromboembolic events, or asymptomatic intracardiac thrombosis. The primary safety outcome was the occurrence of major bleeding. RESULTS Of 220 participants, 218 (109 per group) were included in the modified intention-to-treat analysis. The primary efficacy outcome occurred in 4 patients (3.7%) taking warfarin and none taking edoxaban (risk difference, -0.0367; 95% confidence interval, -0.0720 to -0.0014; P < .001 for noninferiority). The primary safety outcome occurred in 1 patient (0.9%) taking warfarin and 3 patients (2.8%) taking edoxaban (risk difference, 0.0183; 95% confidence interval, -0.0172 to 0.0539; P = .013 for noninferiority). CONCLUSIONS Edoxaban is noninferior to warfarin for preventing thromboembolism and is potentially comparable for risk of major bleeding during the first 3 months after surgical bioprosthetic valve implantation or valve repair.

Abstract
Patients with leukemia are at an increased risk for infective endocarditis secondary to their immunocompromised state, chemotherapy, and specific risk factors such as the presence of indwelling central venous catheters. There is a paucity of data regarding temporal trends and clinical outcomes of infective endocarditis in leukemia patients. Previous studies have shown a high rate of complications related to surgical valve procedures for treatment of infective endocarditis in patients with hematological malignancies. In this study, we aimed to analyze the contemporary trends and clinical outcomes of treatment in infective endocarditis patients with and without leukemia based on data available from the Nationwide Inpatient Sample, which is a publicly accessible, large sample-sized national dataset of hospitalized patients across the US. We present key findings on baseline characteristics, microbiological profile, outcomes, rates of valve surgical procedures, and mortality in infective endocarditis patients with and without leukemia between 2002 and 2017 in the US.

Duchnowski P. The Role of the N-Terminal of the Prohormone Brain Natriuretic Peptide in Predicting Postoperative Multiple Organ Dysfunction Syndrome. J Clin Med 2022; 11:jcm11237217. [PMID: 36498791 PMCID: PMC9740192 DOI: 10.3390/jcm11237217] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/14/2022] [Revised: 11/30/2022] [Accepted: 12/02/2022] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND Multiple organ dysfunction syndrome (MODS) is the progressive and potentially reversible dysfunction of at least two organ systems in the course of an acute and life-threatening disorder of systemic homeostasis. MODS is a serious post-cardiac-surgery complication in valvular heart disease that is associated with a high risk of death. This study assessed the predictive ability of selected preoperative and perioperative parameters for the occurrence of MODS in the early postoperative period in a group of patients with severe valvular heart disease. METHODS Subsequent patients with significant symptomatic valvular heart disease who underwent cardiac surgery were recruited in the study. The main end-point was postoperative MODS, defined as a dysfunction of at least two organs-perioperative stroke, heart failure requiring mechanical circulatory support, respiratory failure requiring mechanical ventilation, and postoperative acute kidney injury requiring renal replacement therapy. A logistic regression was used to assess relationships between variables. RESULTS There were 602 patients recruited for this study. The main end-point occurred in 40 patients. Preoperative NT-proBNP (OR 1.026; 95% CI 1.012-1.041; p = 0.001) and hemoglobin (OR 0.653; 95% CI 0.503-0.847; p = 0.003) are independent predictors of the primary end-point in a multivariate regression analysis. The cut-off point for the NT-proBNP value for postoperative MODS was calculated at 1300 pg/mL. CONCLUSIONS A high preoperative level of NTpro-BNP may be associated with the onset of MODS in the early postoperative period. The results of the study may also suggest that earlier cardiac surgery for significant valvular heart disease may be associated with an improved prognosis in this group of patients.

Abstract
BACKGROUND Women have a higher risk of mortality than men after cardiac surgery independent of other risk factors. The reason for this may not be limited to patient-specific variables. Failure to rescue (FTR) patients from death after a postoperative complication is a nationally endorsed quality care metric. We aimed to identify whether sex disparities exist in the quality of care after cardiac surgery using FTR rates. METHODS A retrospective analysis of 30 973 men (70.4%) and 13 033 women (29.6%) aged over 18 years undergoing coronary artery bypass graft or valve surgery in New York (2016-2019) and California (2016-2018) who experienced at least one serious postoperative complication. The primary outcome was the FTR. Multivariable logistic regression was used to identify predictors of death after complication. Propensity matching was used to adjust for baseline differences between sexes and yielded 12 657 pairs. RESULTS Female patients that experienced complications were older (mean age 67.8 versus 66.7, P<0.001), more frail (median frailty score 0.1 versus 0.07, P<0.001), and had more comorbidities (median Charlson score 2.5 versus 2.3, P<0.001) than male patients. The overall FTR rate was 5.7% (2524), men were less likely to die after a complication than women (4.8% versus 8%, P<0.001). Independent predictors of FTR included female sex (relative risk [RR]: 1.46 [CI, 1.30-1.62]), area-level poverty rate >20% (RR, 1.21 [CI, 1.01-1.59]), higher frailty (RR, 2.83 [CI, 1.35-5.93]), undergoing concomitant coronary artery bypass graft and valve surgeries (RR, 1.69 [CI, 1.49-1.9]), and higher number of postoperative complications (RR, 16.28 [CI, 14-18.89]). In the propensity-matched cohorts, the FTR rate remained significantly lower among men than women (6.0% versus 8.0%, P<0.001). CONCLUSIONS Women are less likely to be rescued from death following postoperative complications, independent of socioeconomic and clinical characteristics. Further research is warranted to investigate the clinical practices contributing to this disparity in quality of care following cardiac surgery.

Angioplasty balloon occlusion of LIMA graft in reoperations of patients with prosthetic valve endocarditis and patent LIMA-LAD graft. KARDIOCHIRURGIA I TORAKOCHIRURGIA POLSKA = POLISH JOURNAL OF CARDIO-THORACIC SURGERY 2022; 19:199-204.

Abstract
Introduction Myocardial protection in reoperative cardiac surgery is extremely difficult in patients with previous coronary surgery and a working LAD-LIMA graft. We use the method of percutaneous angiographic balloon left internal mammary artery (LIMA) occlusion and cardioplegic arrest. Aim To compare the data of patients with angiographic balloon LIMA-occlusion and those without occlusion in operations related to prosthetic valve endocarditis (PVE), and determine the degree of safety and benefits of the method. Material and methods A total of 20 patients undergoing surgery for PVE with a patent LIMA-LAD graft were analyzed retrospectively. We divided the patients into 2 groups: group A - patients with LIMA occlusion; and group B - patients without LIMA occlusion. The pre-, intra- and postoperative results were compared and the degree of safety and benefits of the application of the method were studied. Results 80% of patients in group A needed only dopamine infusion and 20% needed the addition of a second catecholamine at the end of CPB. In group B, the need for double catecholamine maintenance was noted in 50% of patients. The need for implantation of an intra-aortic balloon pump due to refractory heart failure was registered in 10% of patients in group A and in 20% of patients in group B. In terms of survival, mortality in the group with LIMA occlusion was 0%, while in the group without LIMA occlusion it was 20%. Conclusions Our observations suggest that angiographic balloon LIMA occlusion is a reliable, easily applicable and relatively safe technique that improves the surgical results.

Risk Factors of Sudden Cardiac Arrest during the Postoperative Period in Patient Undergoing Heart Valve Surgery. J Clin Med 2022; 11:jcm11237098. [PMID: 36498672 PMCID: PMC9737591 DOI: 10.3390/jcm11237098] [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: 10/20/2022] [Revised: 11/24/2022] [Accepted: 11/28/2022] [Indexed: 12/05/2022] Open
Abstract
BACKGROUND Sudden cardiac arrest (SCA) is the sudden cessation of normal cardiac activity with hemodynamic collapse. This usually leads to sudden cardiac death (SCD) when cardiopulmonary resuscitation is not undertaken. In patients undergoing heart valve surgery, postoperative SCA is a complication with a high risk of death, cerebral hypoxia and multiple organ dysfunction syndrome (MODS). Therefore, knowledge of the predictors of postoperative SCA is extremely important as it enables the identification of patients at risk of this complication and the application of the special surveillance and therapeutic management in this group of patients. The aim of the study was to evaluate the usefulness of selected biomarkers in predicting postoperative SCA in patients undergoing heart valve surgery. METHODS This prospective study was conducted on a group of 616 consecutive patients with significant valvular heart disease that underwent elective valve surgery with or without coronary artery bypass surgery. The primary end-point at the intra-hospital follow-up was postoperative SCA. The secondary end-point was death from all causes in patients with postoperative SCA. Patients were observed until discharge from the hospital or until death. Logistic regression was used to assess the relationships between variables. RESULTS The postoperative SCA occurred in 14 patients. At multivariate analysis, only NT-proBNP (odds ratio (OR) 1.022, 95% confidence interval (CI) 1.012-1.044; p = 0.03) remained independent predictors of the primary end-point. Age and NT-proBNP were associated with an increased risk of death in patients with postoperative SCA. CONCLUSIONS The results of the presented study indicate that SCA in the early postoperative period in patients undergoing heart valve surgery is an unpredictable event with high mortality. The potential predictive ability of the preoperative NT-proBNP level for the occurrence of postoperative SCA and death in patients after SCA demonstrated in the study may indicate that the overloaded and damaged myocardium in patients undergoing heart valve surgery is particularly sensitive to non-physiological conditions prevailing in the perioperative period, which may cause serious hemodynamic disturbances in the postoperative period and lead to death.

Abstract
A 78 years old patient underwent his third biological aortic valve replacement (25 mm, Inspiris ResiliaTM, Edwards Lifesciences LLC, Irvine, USA) with COR-KNOT® (LSI Solutions, Victor, NY, USA) due to valve degeneration in 2018 at a foreign hospital. In 2021, the patient was diagnosed with severe aortic regurgitation and admitted to our hospital for his fourth surgery. Intraoperatively, a total of seven perforations in all three valve leaflets have been observed, which were obviously induced by the rigid metallic fasteners. Redo isolated aortic valve replacement (29 mm, Perimount Magna Ease, Edwards Lifesciences LLC, Irvine, USA) was performed with conventionally knotted, pledget enforced braided threads. Postoperative course was uneventful. This report shows that COR-KNOT® induced defects do not appear immediately after surgery but within the first four postoperative months. Since failure of aortic bioprostheses due to arotic insufficiency is often rated as "early degeneration" and degenerated aortic bioprostheses are mostly replaced by valve-in-valve strategy, the true incidence of this serious complication might be underestimated. COR-KNOT® should be used with caution in biological aortic valve replacement and patients should undergo close postoperative follow-ups.

Abstract
Background An intra-cardiac abscess is a serious complication of both native (NV-IE) and prosthetic valve infective endocarditis (PV-IE). Despite being an accepted indication for surgery, controversies remain regarding the optimal timing and type of operation. We aimed to report the outcomes of patients managed for intra-cardiac abscesses over more than a decade. Methods Patients aged ≥18 years managed for intra-cardiac abscess between 1 January 2005 and 31 December 2017 were identified from a prospectively collected IE database. The primary outcome was 30-day mortality in operated patients and secondary outcomes were freedom from re-infection, re-operation and long-term mortality comparing those patients with aortic root abscess who underwent aortic valve replacement (AVR) and those who received aortic root replacement (ARR). Results Fifty-nine patients developed an intra-cardiac abscess, and their median age was 55 (43-71) years; among them, 44 (75%) were men, and 10 (17%) were persons who injected drugs. Infection with beta-haemolytic streptococci was associated with NV-IE (p = 0.009) and coagulase-negative staphylococci with PV-IE (p = 0.005). Forty-four (75%) underwent an operation, and among those with aortic root abscess, 27 underwent AVR and 12 ARR. Thirty-day mortality was associated with infection with S. aureus (p = 0.006) but not the type or timing of the operation. Survival in operated patients was 66% at 1 year and 59% at 5 years. In operated patients, none had a relapse, although six developed late recurrence. Freedom from infection, re-operation and long-term mortality were similar in patients undergoing AVR compared to ARR. Conclusion Patients diagnosed with intra-cardiac abscess who were not operated on had very poor survival. In those who underwent an operation, either by AVR or ARR based upon patient factors, imaging and intra-operative findings outcomes were similar.

Abstract
Treatment of infective endocarditis can often prove challenging due to its wide range of anatomical presentations. When complicated by an aortic root abscess, patients may require extensive root surgery, which on its own leads to a worse outcome. We present our experience with a surgical technique for reinforcing the aortic annulus with a ring from a Dacron aortic prosthesis placed in the left ventricular outflow tract to avoid the need for root replacement procedures or patch closures of the defect. The technique described in this paper provides a viable alternative to the standard techniques used for the treatment of annular abscesses in aortic valve endocarditis. Due to the relative simplicity and ease of use, this approach may present a means of reducing operation time and possibly postoperative complications of this severe condition.

Abstract
Obesity has been associated with increased incidence of comorbidities and shorter life expectancy, and it has generally been assumed that patients with obesity should have inferior outcomes after surgery. Previous literature has often demonstrated equivalent or even improved rates of mortality after cardiac surgery when compared to their lower-weight counterparts, coined the obesity paradox. Herein, we aim to review the literature investigating the impact of obesity on surgical valve interventions. PubMed and Embase were systematically searched for articles published from 1 January 2000 to 15 October 2021. A total of 1315 articles comparing differences in outcomes between patients of varying body mass index (BMI) undergoing valve interventions were reviewed and 25 were included in this study. Patients with higher BMI demonstrated equivalent or reduced rates of postoperative myocardial infarction, stroke, reoperation rates, acute kidney injury, dialysis and bleeding. Two studies identified increased rates of deep sternal wound infection in patients with higher BMI, although the majority of studies found no significant difference in deep sternal wound infection rates. The obesity paradox has described counterintuitive outcomes predominantly in coronary artery bypass grafting and transcatheter aortic valve replacement. Recent literature has identified similar trends in other heart valve interventions. While the obesity paradox has been well characterized, its causes are yet to be identified. Further study is essential in order to identify the causes of the obesity paradox so patients of all body sizes can receive optimal care.

Abstract
Over the last several years multiple studies, primarily from European centers have demonstrated the clinical and outcomes benefits of multidisciplinary endocarditis teams. Despite this literature, adoption of this approach to patient care has been slower in the United States. While there is literature outlining the optimal composition of an endocarditis team, there is little information to guide providers as they attempt to transform practice from a fragmented, disjointed process to an efficient, collaborative care model. In this review, the authors will outline the steps they took to create and implement a successful multidisciplinary endocarditis team at the University of Michigan. In conjunction with existing data, this piece can be used as a resource for clinicians seeking to improve the care of patients with endocarditis at their institutions.

Abstract
BACKGROUND Atrial fibrillation is the main complication of patients who suffer from valvular heart disease (VHD), which may lead to an increased susceptibility to ventricular tachycardia, atrial dysfunction, heart failure, and stroke. Therefore, seeking a safe and effective therapy is crucial in prolonging the lives of patients with VHD and improving their quality of life. METHODS Our target database included PubMed, Web of Science, Embase, and Cochrane Library, from which published articles were retrieved from inception to June 2020. We retrieved all randomized controlled trials (RCTs) that compared patients undergoing valve surgery with (VSA) or without ablation (VS) procedure. Studies to be included were screened and data extraction was performed independently by 2 investigators. The Cochrane risk-of-bias table was used to evaluate the methodological quality of the included RCTs. The mean difference (MD) with 95% confidence interval (CI) and relative risk (RR) ratio was calculated to analyze the data. Heterogeneity was evaluated using I2 and chi-square tests. Egger test and the trim and fill analysis were used to further determine publication bias. RESULTS Fourteen RCTs that included 1376 patients were eventually selected for this meta-analysis. Surgical ablation was found to be effective in restoring sinus rhythm in valvular surgery patients at discharge (RR 2.91, 95% CI [1.17, 7.20], I2 97%, P = .02), 3 to 6 months (RR 2.85, 95% CI [2.27, 3.58], I2 49%, P < .00001), 12 months, and more than 1 year after surgery (RR 3.54, 95% CI [2.78, 4.51], I2 27%, P < .00001). All-cause mortality (RR 0.98, 95% CI [0.64, 1.51], I2 0%, P = .94) and stroke (RR 1.29, 95% CI [0.70, 2.39], I2 0%, P = .57) were similar in the VSA and VS groups. Compared with VS, VSA prolonged cardiopulmonary bypass time (MD 30.44, 95% CI [17.55, 43.33], I2 88%, P < .00001) and aortic cross-clamping time (MD 19.57, 95% CI [11.10, 28.03], I2 89%, P < .00001). No significant differences were found between groups with respect to the risk of bleeding (RR 0.64, 95% CI [0.37, 1.12], I2 0%, P = .12), heart failure (RR 1.11, 95% CI [0.63, 1.93], I2 0%, P = .72), and low cardiac output syndrome (RR 1.41, 95% CI [0.57, 3.46], I2 18%, P = .46). However, the demand for implantation of a permanent pacemaker was significantly higher in the VSA group (RR 1.84, 95% CI [1.15, 2.95], I2 0%, P = .01). CONCLUSION Although we found high heterogeneity in the restoration of sinus rhythm at discharge, we assume that the comparison is valid at this time, given the current state in the operating room. This study provides evidence of the efficacy and security of concomitant ablation intervention for patients with VHD and atrial fibrillation. Surgical ablation would increase the safety of implantation of a permanent pacemaker in the population that underwent valve surgery.

Abstract
OBJECTIVES To evaluate 20 days and 3 months follow-up effectiveness of cardiac rehabilitation (CR) enhanced by resistance/balance training and telephone-support program compared to usual CR care in improving quality of life, clinical course and physical activity behavior. DESIGN Single-centre randomized controlled trial. SETTING Inpatient CR clinic. SUBJECTS 116 (76.1 ± 6.7 years, 50% male) patients 14.5 ± 5.9 days after valve surgery/intervention were randomized to intervention group (IG, n = 60) or control group (CG, n = 56). INTERVENTION Additional resistance/balance training (3 days/week) during phase-II CR and telephone-support program during 3-month follow-up. CG patients were provided with usual CR care. MAIN MEASURES Short Form 36 Health Survey scales, European Quality of Life 5 Dimensions 3 Level Version QoL index, visual analog scale, clinical course, and physical activity behavior assessed with standardized questionnaires. RESULTS IG reported statistically significant higher mental component score (48.5 ± 6.91 vs. 40.3 ± 11.21 at the baseline, 50.8 ± 9.76 vs. 42.6 ± 9.82 after 20 days, 49.4 ± 8.45 vs. 40.5 ± 8.9 after 12 weeks follow up), general health (48.6 ± 3.17 vs. 45.0 ± 2.95 at the baseline, 53.6 ± 3.02 vs. 43.8 ± 2.55 after 20 days, 53.2 ± 3.11 vs. 44.2 ± 3.07 after 12 weeks) and role limitations due to emotional problems (48.5 ± 15.2 vs. 27.7 ± 11.5 at the baseline, 72.7 ± 12.6 vs. 30.5 ± 11.2 after 20 days, 66.6 ± 14.2 vs. 36.1 ± 11.2 after 12 weeks) in all three assessments (p < 0.05). CG patients had more documented hospital admissions (4 (8%) vs 10 (25%), p = 0.027), atrial fibrillation paroxysms (3 (6.0%) vs. 10 (35.0%), p = 0.011) and blood pressure swings (13 (26%) vs. 20 (50%), p = 0.019). IG patients chose more different physical activities (1.7 ± 0.7 vs. 1.25 ± 0.63, p = 0.002), spent more time being physical active every day (195.6 ± 78.6 vs. 157.29 ± 78.8, p = 0.002). CONCLUSIONS The addition of resistance/balance exercises and telephone-support program 12 weeks after to the CR could linked to higher physical activity levels and fewer clinical complications but did not lead to a significant improvement in quality of life.

Gatta F, Haqzad Y, Loubani M. Permanent pacemaker post- valve surgery: Do valve type and position matter? A propensity score matching study. J Clin Transl Res 2021; 7:786-791. [PMID: 34988330 PMCID: PMC8710354] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Revised: 11/21/2021] [Accepted: 11/21/2021] [Indexed: 10/26/2022] Open
Abstract
BACKGROUND AND AIM This study evaluates whether aortic valve replacement (AVR) or mitral valve replacement (MVR) with biological versus mechanical prostheses is independent risk factors for permanent pacemaker (PPM) post-cardiac surgery, alongside traditionally accepted determinants. METHODS This study focused on single-centre retrospective analysis of 10 years of activity. Case-control 1-to-9 matching was performed for 7 pre-operative and 2 intraoperative confounding factors. RESULTS After matching, 617 patients were included for analysis: AVR (79.4% n=490) and MVR (20.6% n=127). PPM was implanted in 3.7% (n=18) and 3.1% (n=4), P=0.8, respectively. A further analysis for PPM rate in biological versus mechanical prostheses did not provide any significant result (P=0.6 AVR and P=0.8 MVR). Post-operative complications in AVR and MVR groups were as follows: Reopening (4.5% vs. 6.3%, P=0.4), myocardial infarction (0.8% vs. 3.2%, P=0.04), pulmonary (32.9% vs. 38.6%, P=0.3), neurological (9.2% vs. 11.8%, P=0.4), renal (9.8% vs. 7.9%, P=0.5), wound (1.4% vs. 2.4%, P=0.5), infective (5.5% vs. 8.7%, P=0.2), and multiple organ failure (4.9% vs. 5.5%, P=0.6). The length of intensive care unit (hours) and hospital stay (days) was 71±163.8 versus 106.5±243.7 (P=0.5) and 14.7±14.7 versus 18.9±20.8 (P=0.01). In-hospital mortality resulted in 4.1% for AVR and 3.9% for MVR, P=0.9. CONCLUSION Valve position and valve type do not affect the likelihood of requiring permanent pacing in patients undergoing isolated aortic and MVR. RELEVANCE FOR PATIENTS A significant proportion of patients undergoing cardiac surgery develop arrhythmias and conduction disturbances postoperatively, often requiring the implantation of a PPM. Determining factors associated with an increase likelihood of permanent pacing would allow the optimization of per- and intra-operative care, with the aim of reducing the incidence of patients requiring post-operative PPM insertion.

Abstract
OBJECTIVES This review aimed to evaluate the safety and efficacy of concomitant surgical ablation (SA) for patients with atrial fibrillation (AF) undergoing rheumatic mitral valve (MV) surgery. METHODS A systematic search of relevant studies focusing on SA for patients with AF undergoing rheumatic MV surgery was performed. The primary outcomes included mortality, efficacy, and complications. RESULTS Four randomized controlled trials (RCTs) and four observational studies covering 1931 patients met the inclusion criteria. In RCTs, no significant differences in reoperation for bleeding, low cardiac output syndrome, thromboembolic events, and early (risk ratio [RR], 2.07; 95% confidence intervals [CI], 0.37-11.40; p = .41) and midterm all-cause death (RR, 1.07; 95% CI, 0.40-2.88; p = .89) were noted between the SA group and the nonablation group. These results were similar to those obtained from observational studies. However, ablation was associated with a higher incidence of permanent pacemaker implantation (RR, 2.44; 95% CI, 1.15-5.18; p = .02) in observational studies but not in RCTs (RR, 2.03; 95% CI, 0.19-21.26; p = .56). Furthermore, additional SA was significantly more effective in sinus rhythm (SR) restoration than MV surgery alone at discharge and at the 12-month and 3-year follow-ups. CONCLUSIONS Concomitant SA during rheumatic MV surgery does not increase perioperative adverse events. In addition, SA promotes considerable restoration of SR. Although some evidence exists that permanent pacemaker implantation is more common after ablation, not all studies support this notion.

Comparison of risk scores for predicting outcomes after isolated tricuspid valve surgery. J Card Surg 2021; 37:126-134. [PMID: 34672020 DOI: 10.1111/jocs.16098] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2021] [Revised: 09/21/2021] [Accepted: 09/27/2021] [Indexed: 12/13/2022]
Abstract
BACKGROUND Risk models play important roles in stratification and decision-making towards cardiac surgery. Isolated tricuspid valve surgery is a high risk but increasingly performed the operation, however, the performance of risk models has not been externally evaluated in these patients. We compared the prognostic utility of contemporary risk scores for isolated tricuspid valve surgery. METHODS Consecutive patients undergoing isolated tricuspid valve surgery at Cleveland Clinic during 2004-2018 were evaluated in this cohort study. EuroSCORE II, Society of Thoracic Surgeon's tricuspid (STS-TVS) score, and the Model for End-stage Liver Disease (MELD) score were retrospectively calculated, and their performance for predicting operative mortality, postoperative complications, and mortality during follow-up was assessed. RESULTS Amongst 207 patients studied, the mean age was 54.1 ± 17.9 years, 116 (56.0%) were female, 92 (44.4%) had secondary tricuspid regurgitation, and 151 (72.9%) had a surgical repair. Mean EuroSCORE II, STS-TVS, and MELD scores were 6.3 ± 6.6%, 5.5 ± 6.2%, and 9.8 ± 4.7, respectively. C-statistics (95% confidence intervals) for operative mortality were 0.83 (0.74-0.93) for EuroSCORE II, 0.60 (0.45-0.75) for STS-TVS score, and 0.74 (0.58-0.89) for MELD score, while observed/expected ratios were 0.78 and 0.89 for the first two scores. All three scores were associated with mortality during follow-up and discriminated most postoperative complications. CONCLUSION EuroSCORE II was superior to STS-tricuspid score for isolated TVS risk assessment. Although surgical risk scores traditionally underestimated operative mortality after isolated tricuspid valve surgery, they did not in our cohort, reflecting the excellent surgical results. The simple MELD score performed similarly to the EuroSCORE II, especially for discriminating morbidities.

Abstract
Cardiovascular disease remains the leading cause of morbidity and mortality for women in United States and worldwide. One in 3 women dies from cardiovascular disease, and 45% of women >20 years old have some form of CVD. Historically, women have had higher morbidity and mortality after cardiac surgery. Sex influences pathogenesis, pathophysiology, presentation, postoperative complications, surgical outcomes, and survival. This review summarizes current cardiovascular surgery outcomes as they pertain to women. Specifically, this article seeks to address whether sex disparities in research, surgical referral, and outcomes still exist and to provide strategies to close these gaps. In addition, with the growing population of women of reproductive age with cardiovascular disease and cardiovascular risk factors, indications for cardiac surgery arise in pregnant women. The current review will also address the unique issues associated with this special population.

Abstract
Background Infective endocarditis is associated with higher mortality in elderly patients, but the role of surgery in this group has not been fully evaluated. The aim of this study was to assess outcomes of left‐sided infective endocarditis in elderly patients and to determine the influence of surgery on mortality in the elderly. Methods and Results A nationwide retrospective study was performed of 2186 patients with left‐sided infective endocarditis recorded in the SRIE (Swedish Registry of Infective Endocarditis), divided into patients aged <65 years (n=864), 65 to 79 years (n=806), and ≥80 years (n=516). Survival analysis was performed using the Swedish National Population Registry, and propensity score matching was applied to assess the effect of surgery on survival among patients of all ages. The rate of surgery decreased with increasing age, from 46% in the <65 group to 6% in the ≥80 group. In‐hospital mortality was 3 times higher in the ≥80 group compared with the <65 group (23% versus 7%) and almost twice that of the 65 to 79 group (12%). In propensity‐matched groups, the mortality rate was significantly lower between the ages of 55 and 82 years in patients who underwent surgery compared with patients who did not undergo surgery. Surgery was also associated with better long‐term survival in matched patients who were ≥75 years (hazard ratio, 0.36; 95% CI, 0.24–0.54 [P<0.001]). Conclusions The proportion of elderly patients with infective endocarditis who underwent surgery was low compared with that of younger patients. Surgery was associated with lower mortality irrespective of age. In matched elderly patients, long‐term mortality was higher in patients who did not undergo surgery, suggesting that surgery is underused in elderly patients.

Abstract
BACKGROUND Techniques and results of aortic valve repair remain challenging. AIMS Safari et al. seek to improve aortic valve repair by either aortic patching or valve sparing root replacement. MATERIALS AND METHODS The results of bicuspid aortic valve (BAV) repair in 142 patients were examined withor without valve sparing root replacement. RESULTS Isolated BAV repair with or without valve sparing root replacement provided goodclinical outcomes with relatively low reoperation rate and durable valve function. DISCUSSION While clinical outcome from BAV repair was generally good, the authors have stopped pericardial patch augmentation of BAV leaflets due to suboptimal durability. CONCLUSION Thelack of a durable valve patch material and the modest durability of BAV repairin general point out that aortic valve repair remains an ongoing struggle inmaterial science.

Abstract
Background: To date, there is no reference for a 6-min walk test distance (6-MWD) immediately after cardiac surgery. Therefore, this study aimed to identify the determinants and to generate equations for prediction reference for 6-MWD in patients immediately after cardiac surgery. Methods: This is a cross-sectional study of the 6-min walk test (6-MWT) prior to participation in the cardiac rehabilitation (CR) program of patients after coronary artery bypass surgery (CABG) or valve surgery. The 6-MWT were carried out in a gymnasium prior to the CR program immediately after the cardiac surgery. Available demographic and clinical data of patients were analyzed to identify the clinical determinants of 6-MWD. Results: This study obtained and analyzed the data of 1,509 patients after CABG and 632 patients after valve surgery. The 6-MWD of all patients was 321.5 ± 73.2 m (60–577). The distance was longer in the valve surgery group than that of patients in the CABG group (327.75 ± 70.5 vs. 313.59 ± 75.8 m, p < 0.001). The determinants which significantly influence the 6-MWD in the CABG group were age, gender, diabetes, atrial fibrillation, and body height, whereas in the valve surgery group these were age, gender, and atrial fibrillation. The multivariable regression models generated two formulas using the identified clinical determinants for patients after CABG: 6-MWD (meter) = 212.57 + 30.47 (if male gender) − 1.62 (age in year) + 1.09 (body height in cm) − 12.68 (if with diabetes) − 28.36 (if with atrial fibrillation), and for patients after valve surgery with the formula: 6-MWD (meter) = 371.05 + 37.98 (if male gender) − 1.36 (age in years) − 10.61 (if atrial with fibrillation). Conclusion: This study identified several determinants for the 6-MWD and successively generated two reference equations for predicting 6-MWD in patients after CABG and valve surgery.

Abstract
Prosthetic aortic valve replacements have long been the mainstay of valvular surgery due to their favorable outcomes and low operative complexity. Yet, mechanical valves require lifelong anticoagulation, whereas bioprosthetic valves increase the risk for earlier and more frequent reoperation. Alternative reconstructive techniques have been proposed to address these challenges. These include valve-sparing root replacement procedures if the native aortic valve can be salvaged, and the Ross procedure, which nearly eliminates prosthetic valve-related thromboembolism, anticoagulation-related hemorrhage and endocarditis. Both procedures are technically more complex and thus subject to surgeons' volume and expertise compared to conventional aortic valve replacements. However, they are associated with more favorable outcomes compared to aortic valve replacements if performed by experienced surgeons, especially in younger patients. Nevertheless, despite the growing high-quality literature supporting both procedures, existing multi-society guidelines fail to acknowledge the strength of evidence in support of valve-sparing root replacement procedures and the Ross procedure. In this review, we summarize the existing long-term evidence for the use of each procedure, describe the current guidelines for the treatment of aortic valve pathology, and propose the reevaluation of guidelines based on the available clinical evidence.

Abstract
Background Potential for difficult reoperations has been a concern for patients undergoing a Ross procedure. Data regarding the outcomes of such reoperations is extremely limited. We examined our experience to define the current scope and risk of these operations. Methods Between 1996 and 2020, 83 patients who had a previous Ross procedure underwent 89 reoperative surgeries. There were 72 males and average age was 48 with a range of 18-76. Twenty-four patients had more than one prior reoperation, with five patients having more than one reoperation post Ross. Patients were stratified by primary reason for reoperation including autograft dysfunction, homograft dysfunction, or other cardiac surgical problems. Demographic, operative, and outcomes data were collected from clinical records and placed in a secure data base for analysis. Results A total of 176 procedures were done in the 89 operations. Autograft dysfunction affected 68 patients. Homograft dysfunction affected 27 patients. Both of these were seen in 17 patients. Other cardiac problems required 79 other procedures. There were two (2.2%) operative deaths, with perioperative morbidity affecting six patients (6.7%). Survival following reoperation after Ross was 82.3% and 77.5% (±2), at ten and fifteen years respectively. Conclusions Reoperations after a Ross procedure can be challenging but can be done with a high degree of safety and long-term benefit in experienced hands.

Abstract
BACKGROUND Isolated tricuspid valve (TV) surgery has higher mortality compared with other single-valve operations. The optimal timing and indications remain controversial, and earlier surgery before the development of class I surgical indications may improve outcomes. We aimed to compare the characteristics and outcomes of surgery for isolated tricuspid regurgitation (TR), based on class I indication versus an earlier operation. METHODS Consecutive patients undergoing isolated TV surgery for TR without other concomitant valve surgery at our center during 2004 to 2018 were studied. Indications were divided into class I versus earlier surgery (asymptomatic severe TR with right ventricular dilation and/or dysfunction) for comparative analyses of characteristics and outcomes. The primary outcome was mortality. RESULTS The study included 159 patients (91 females [57.2%]; 115 for class I, 44 for early surgery), with a mean age of 59.7 ± 15.6 years, 119 (74.8%) with surgical repairs, and a mean follow-up of 5.1 ± 4.0 years. Overall operative mortality was 5.1% (8 patients) (class I, 7.0%; early surgery, 0.0%; P = .107), and class I had a higher composite morbidity than early surgery (35.7% [n = 41] vs 18.2% [n = 8]; P = .036). On Cox proportional hazard model analysis, class I versus early surgery (hazard ratio [HR], 4.62; 95% confidence interval [CI], 1.09-19.7; P = .04), age (HR, 1.03; 95% CI, 1.00-1.07; P = .046), and diabetes (HR, 2.50; 95% CI, 1.13-5.55; P = .024) were independently associated with higher mortality during follow-up. CONCLUSIONS Patients with class I indication for isolated TV surgery had worse survival compared with those undergoing earlier surgery before reaching class I indication. Earlier surgery may improve outcomes in these high-risk patients.
