Percutaneous left atrial appendage occlusion in mitral valve disease: A Nationwide Readmission Database analysis. CARDIOVASCULAR REVASCULARIZATION MEDICINE 2024; 63:23-30. [PMID: 38267285 DOI: 10.1016/j.carrev.2024.01.007] [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: 11/27/2023] [Accepted: 01/10/2024] [Indexed: 01/26/2024]
Abstract
BACKGROUND Percutaneous left atrial appendage occlusion (LAAO) has emerged as a non-pharmacologic alternative to oral anticoagulation in reducing stroke risk in AF patients. However, patients with mitral valve disease (MVD), who are expected to have a significantly greater risk of left atrium (LA) thrombus formation and embolic stroke were excluded from randomized trials examining percutaneous LAAO. To address this gap, we present a national registry analysis of the use of LAAO among patients with MVD. METHODS Using the National Readmissions Database, we performed a retrospective review of all hospitalizations for LAAO identified between September 2015 and November 2019. Of these, patients with ICD-10 codes for MVD were identified. Propensity matched (PSM) analysis was used to compare patients with MVD with a matched sample of patients undergoing LAAO with non-valvular AF. Outcomes examined included all-cause mortality, stroke, major bleeding, pericardial effusion (PE), and tamponade. RESULTS 51,540 patients who underwent LAAO without a history of MVD and 3777 with a history of MVD were identified. Crude analysis demonstrated the odds of mortality, PE, and cardiac tamponade during index hospitalization to be higher in the MVD group. The length of stay and cost of index hospitalization were also slightly greater for the MVD group. A sample of 7649 patients (MVD: 3777 MVD and no MVD: 3872) were selected for PSM analysis with similar comorbidities across the two groups. In the PSM comparison, MVD was associated with higher risk of PE. The MVD group had a slightly higher rate of readmissions the association with PE remained at 30-day readmission (OR: 2.099 [1.360-3.238], p-value: <0.001). CONCLUSION To our knowledge, this is the first study examining the use of LAAO among MVD patients. Our findings suggest that patients with MVD who underwent LAAO had a higher risk of post-procedural PE without an increase in mortality, stroke, or major bleeding. These results provide a rationale for considering LAAO as part of the stroke prevention strategy among patients with valvular AF.

Incidence, progression, and predictors of left atrial appendage sealing after Watchman FLX device implantation with computed tomographic assessment. Catheter Cardiovasc Interv 2024. [PMID: 38662126 DOI: 10.1002/ccd.31044] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/26/2023] [Revised: 02/13/2024] [Accepted: 03/31/2024] [Indexed: 04/26/2024]
Abstract
BACKGROUND Limited data exists regarding incidence, progression, and predictors of left atrial appendage (LAA) sealing after transcatheter LAA closure. We aimed to evaluate the incidence, progression, and predictive factors associated with LAA sealing after LAA closure. METHODS This study includes patients who underwent successful LAA closure with Watchman FLX device and had both pre- and postprocedural computed tomography (CT). Postprocedural CT was performed 45 days after LAA closure and used to evaluate residual LAA patency. Patient who had residual LAA patency at 45 days underwent 1-year follow-up CT. RESULTS A total of 105 patients (mean age: 75.2 ± 9.6 years; 53.3% female) who underwent successful LAA closure with Watchman FLX device and had pre- and postprocedural CT at 45 days were included. Residual patency was observed in 35 (33.3%) patients: 21 (20.0%) patients showed complete contrast opacification in LAA (complete LAA patency) while 14 (13.3%) patients showed contrast opacification only in the distal LAA (distal LAA patency). Among patients with residual LAA patency at 45 days, the rate of LAA sealing at 1 year was significantly higher in the distal LAA patency group than in the complete LAA patency group (75.0% vs. 16.7%; p = 0.019). Increased depth oversizing was associated with both distal LAA patency and complete LAA patency. CONCLUSION Postprocedural CT at 45 days detected patent LAA in one-third of patients after LAA closure. LAA sealing was more frequently observed at 1 year among the distal LAA patency group than the complete LAA patency group.

Abstract
Objective To investigate the burden of tracheal, bronchus, and lung (TBL) cancer due to tobacco exposure in the last 30 years in 12 South American countries. Methods We used the Global Burden of Disease (GBD) 2019 exposure-response function to analyze the total tobacco, smoking, and secondhand smoke exposure-related TBL cancer deaths and disability-adjusted life years (DALYs), for 12 South American countries, between 1990 and 2019. Metrics were described as absolute numbers or rates per 100 000 individuals. The relative change in burden was assessed by comparing the 1990-1994 to 2015-2019 periods. Results In 2019, the all-ages number of TBL cancer deaths and DALYs associated with tobacco exposure in South America was 29 348 and 658 204 in males and 14 106 and 318 277 in females, respectively. Age-adjusted death and DALYs rates for the region in 2019 were 182.8 and 4035 in males and 50.8 and 1162 in females, respectively. In males, 10/12 countries observed relative declines in TBL death rates attributed to tobacco exposure while only 4 countries reduced their mortality in females. Conclusion While significant efforts on tobacco control are under place in South America, substantial burden of TBL cancer persists in the region with significant sex-specific disparities. Increased country-specific primary data on TBL cancer and tobacco exposure is needed to optimize healthcare strategies and improve comprehension of regional trends.

Abstract
Despite ongoing progress in stent technology and deployment techniques, in-stent restenosis (ISR) still remains a major issue following percutaneous coronary intervention (PCI) and accounts for 10.6% of all interventions in the United States. With the continuous rise in ISR risk factors such as obesity and diabetes, along with an increase in the treatment of complex lesions with high-risk percutaneous coronary intervention (CHIP), a substantial growth in ISR burden is expected. This review aims to provide insight into the mechanisms, classification, and management of ISR, with a focus on exploring innovative approaches to tackle this complication comprehensively, along with a special section addressing the approach to complex calcified lesions.

Abstract
Peri-device leak after left atrial appendage closure (LAAC) is often treated with endovascular coils, plugs, or second occluders. This is the first study reporting the Amulet device used for peri-device leak. An 80-year-old male with paroxysmal atrial fibrillation and recurrent falls with head trauma who underwent LAAC with a 24 mm Watchman 2.5 device 3 years ago at another institution was referred to our clinic for management of the peri-device leak. Transesophageal echocardiogram showed persistent residual peri-device leak with 5 mm width along the Coumadin ridge aspect of the device. Computed tomography (CT) also showed the peri-device leak with width of 6 mm and complete opacification of left atrial appendage (LAA). Importantly, CT demonstrated that the Watchman 2.5 device was deployed at distal LAA, leaving the proximal part of LAA with length of 10 mm from ostium. Under general anesthesia, a 22 mm Amulet device was deployed successfully with complete sealing of LAA. Procedure planning is the key to minimize the risk of peri-device leak or device-related thrombosis. Careful assessment of LAA anatomy using multimodality images for peri-device leak after LAAC helped optimal treatment strategy including second LAAC with different type of devices.

Abstract
BACKGROUND While studies have shown the advantages of computed tomography angiography (CTA) over transesophageal echocardiography (TEE) in left atrial appendage closure (LAAC) preprocedural planning for WATCHMAN™ legacy and FLX devices, there has been no reported long-term data for this approach. OBJECTIVES We sought to evaluate long-term outcomes using CTA-based preprocedural planning for LAAC using the WATCHMAN™ device. METHODS A prospective analysis of 231 consecutive patients who underwent LAAC in a single, large academic hospital in the United States was conducted over a 5-year period. CTA-guided preprocedural planning was performed in all. Procedural success, adverse events, length of procedure, number of devices used, and length of stay were evaluated. Rates of death, cerebral embolism, systemic embolism, and major and minor bleeding were recorded. Adjusted predicted stroke and major bleeding rates were derived from CHA2DS2-Vasc and HAS-BLED scores, respectively. RESULTS From January 26, 2017, to November 23, 2021, 231 patients underwent LAAC with CTA preprocedural planning by two operating physicians. The mean age of patients was 76.5 ± 8.4. 59.7% of patients were male. Mean CHA2DS2VASc and HAS-BLED scores were 4.5 ± 1.4 and 3.9 ± 0.9, respectively. All procedures were performed with intracardiac echo (100%). The procedural success rate was 99.1%. The CTA sizing strategy accurately predicted the implant size in 93.5% of patients. Mean number of devices used was 1.10 ± 0.3. Peri-procedural complication rate was 2.2%. 6 patients were lost to follow-up. Mean follow-up was 608.94 days with a total of 377.04 patient years. Median follow-up period of 368 days (interquartile range: 209-1067 days). There were 51 deaths from all causes (13.52 per 100 patient-years), 10 cases of cerebral embolism (2.65 per 100 patient-years), 2 cases of systemic embolism (0.53 per 100 patient-years), 17 cases of major bleeding (4.50 per 100 patient-years), and 31 cases of minor bleeding (8.2 per 100 patient-years). All-cause mortality at 1, 2, and 3 years was 12.7%, 20.9%, and 29.2%, respectively. CV event rates at 1, 2, and 3 years were 2.1%, 6.6%, and 10.5%, respectively. CONCLUSIONS CTA-based preprocedural planning is accurate in predicting device size for LAAC and associated with excellent clinical outcomes at 5 years.

Abstract
Atrial fibrillation is the most common arrhythmia in patients with underlying malignancy. Patients with cancer have a higher risk of bleeding, and at the same time, carry an elevated risk of thromboembolism related to the hypercoagulable state, type of cancer, and anticancer treatment, rendering safe anticoagulation challenging in this population. Left atrial appendage closure is an alternative treatment option in patients with atrial fibrillation and high bleeding risk; however, the data on patients with cancer are limited. Our study aimed to compare the long-term outcomes in patients with cancer receiving left atrial appendage closure using the WATCHMAN device. This is a prospective, single-center study comparing outcomes in 389 patients who underwent percutaneous left atrial appendage closure using the WATCHMAN device over 5 years in a single, large academic hospital in the United States. The postprocedural outcomes of mortality, stroke, and major bleeding were evaluated in patients with and without cancer. Our study included 57 patients with cancer and 332 without cancer. The baseline characteristics were similar between the 2 groups. Metastatic disease was present in 16.4% of patients, and 25% were receiving active treatment at the time of the procedure. The median follow-up time was 354 (interquartile range 85 to 790) days. There was no difference in mortality (hazard ratio [HR] 1.3, 95% confidence interval [CI] 0.72 to 2.35, p = 0.38), major bleeding episodes (HR 1.2, 95% CI 0.45 to 3.33, p = 0.68), and stroke (HR 0.64, 95% CI 0.19 to 2.21, p = 0.49) at 3 years after the procedure in patients with and without cancer. There was no difference in the composite outcome (postprocedural mortality, stroke, and major bleeding) between the 2 groups (HR 1.25, CI 0.75 to 2.07, p = 0.38). Percutaneous left atrial appendage closure in patients with cancer appears to be safe and has a similar long-term risk compared with patients without cancer.

Abstract
AIMS Patients who undergo permanent pacemaker (PPM) implantation after transcatheter aortic valve replacement (TAVR) have a worse outcome. The aim of this study was to identify risk factors of worse outcomes in patients with post-TAVR PPM implantation. METHODS AND RESULTS This is a single-centre, retrospective study of consecutive patients who underwent post-TAVR PPM implantation from 11 March 2011 to 9 November 2019. Clinical outcomes were evaluated by landmark analysis with cut-off at 1 year after the PPM implantation. Of the 1389 patients underwent TAVR during the study duration and a total of 110 patients were included in the final analysis. Right ventricular pacing burden (RVPB) ≥ 30% at 1 year was associated with a higher likelihood of heart failure (HF) readmission [adjusted hazard ratio (aHR): 6.333; 95% confidence interval [CI]: 1.417-28.311; P = 0.016] and composite endpoint of overall death and/or HF (aHR: 2.453; 95% CI: 1.040-5.786; P = 0.040). The RVPB ≥30% at 1 year was associated with higher atrial fibrillation burden (24.1 ± 40.6% vs. 1.2 ± 5.3%; P = 0.013) and a decrease in left ventricular ejection fraction (-5.0 ± 9.8% vs. + 1.1 ± 7.9%; P = 0.005). The predicting factors of the RVPB ≥30% at 1 year were the presence of RVPB ≥40% at 1 month and the valve implantation depth measured from non-coronary cusp ≥4.0 mm (aHR: 57.808; 95% CI: 12.489-267.584; P < 0.001 and aHR: 6.817; 95% CI: 1.829-25.402; P = 0.004). CONCLUSIONS The RVPB ≥30% at 1 year was associated with worse outcomes. Clinical benefit of minimal RV pacing algorithms and biventricular pacing needs to be investigated.

Permanent Pacemaker Insertion Reduction and Optimized Temporary Pacemaker Management After Contemporary Transcatheter Aortic Valve Implantation With Self-Expanding Valves (from the Pristine TAVI Study). Am J Cardiol 2023; 189:1-10.

Abstract
Permanent pacemaker implantation (PPMI) reduction and optimal management of newly acquired conduction disturbances after transcatheter aortic valve implantation (TAVI) are crucial. We sought to evaluate the relation between transcatheter heart valve (THV) implantation depth and baseline and newly acquired conduction disturbances on PPMI after TAVI. This study included 1,026 consecutive patients with severe symptomatic aortic stenosis (mean age 79.7 ± 8.4 years; 47.4% female) who underwent TAVI with the newer-generation self-expanding THVs Primary outcomes were early and late PPMI defined as the need for PPMI during the index admission and between discharge and 30 days, respectively. Early and late PPMI was required for 115 (11.2%) and 21 patients (2.0%), respectively. Early PPMI rates decreased from 26.7% in 2015 and 2016 to 5.7% in 2021, and so did the mean THV depth from 4.4 ± 2.4 mm to 1.8 ± 1.6 mm. Receiver operator characteristics curve analyses showed THV depth had significant discriminatory value for early and late PPMI with cutoff values of 3.0 and 2.2 mm, respectively. Rates of early and late PPMI were significantly lower for patients with shallower compared with deeper implantations (5.1% vs 22.6% and 0.4% vs 4.1%, p <0.001 for both, respectively). Furthermore, rates of early PPMI were lower with shallower implantations in patients with new left bundle branch block after TAVI (2.4% vs 15.9%; p <0.001) and those with baseline right bundle branch block (7.5% vs 29.6%; p = 0.017). Lower rates of PPMI with shallower THV implantation were consistently observed, including in patients with baseline and newly acquired conduction disturbances. Our findings might help optimize the management of a temporary pacemaker after TAVI.

Abstract
The Cor-Knot surgical tying device (LSI Solutions) is an automated suture fastener with a titanium-crimpable sleeve that facilitates a fast and secure knot. The device is an alternative to hand tying, minimizing operation time, and its increasing use is anticipated for minimally invasive cardiac surgeries or in patients with small surgical anatomy. As its use expands, the likelihood of encountering this knotting device during structural interventions may increase. In this case, during the TAVR procedure, the coplanar angle estimated from preoperative computed tomography scan was easily adjusted referencing the line of Cor-Knot in her aortic annulus without administrating contrast despite poor radiodensity from the Trifecta valve. In the coplanar view, the TAVR valve depth was well appreciated in reference to the Cor-Knot line and the TAVR valve was deployed under controlled pacing without contrast use. We achieved mean aortic pressure gradient of 9 mm Hg without paravalvular leakage or conduction abnormalities. She was discharged to home the next day without renal injury.

Abstract
BACKGROUND Though uncommon, pericardial effusion and cardiac tamponade are serious complications of left atrial appendage closure (LAAC). There are few data related to delayed pericardial effusions from this procedure. METHODS This is a single-center prospective analysis of 369 patients who underwent LAAC from December 2016 to March 2022 at a large teaching hospital. We compared patients who developed effusion (n = 5) to patients who did not (n = 364) to determine if there were any factors that predispose patients to developing acute (AEs) or delayed pericardial effusions (DEs). We compared patient characteristics, procedural data, and complications. Unadjusted, stepwise multivariate logistic regression was performed. RESULTS A total of 369 patients underwent LAAC. Of these, 5 patients (1.4%) developed pericardial effusion. Patients in both groups (pericardial effusion vs non-effusion) had similar patient and procedural characteristics. Patients in both groups were older (mean age, 78.4 ± 7.8 years in the effusion group vs 76.3 ± 8.5 years in the non-effusion group; P=.50) and white (60% in the effusion group vs 90.1% in the non-effusion group). CHA2DS2-VASc (4.2 ± 1.1 vs 4.5 ± 1.4; P=.67) and HAS-BLED (3.4 ± 0.5 vs 3.7 ± 0.9; P=.53) scores were similar in the effusion group vs the non-effusion group, respectively. Gastrointestinal bleeding was the most common procedural indication in both groups (80% in the effusion group vs 53.6% in the non-effusion group; P=.23). The majority of the patients in both groups had successful implantation in the first attempt, with the 27-mm device the most commonly used size. There was no significant difference in procedural duration (67 minutes in the effusion group vs 75 minutes in the non-effusion group; P=.16). Among patients who received the Watchman Legacy device, 2 patients developed AEs and no patients had DEs. Of those receiving the Watchman FLX device, 1 patient developed AE and 2 patients developed DEs. All of the patients with effusions had successful recovery. CONCLUSION In this 5-year, single-center experience, DEs were uncommon and potentially related to LAA device anchor microperforation. No statistically significant risk factors predisposing patients to pericardial effusions were identified in our analysis.

Risk Stratification of New Persistent Left Bundle Branch Block After Transcatheter Aortic Valve Implantation. Am J Cardiol 2022; 175:80-87. [PMID: 35597627 DOI: 10.1016/j.amjcard.2022.03.053] [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: 11/29/2021] [Revised: 03/21/2022] [Accepted: 03/28/2022] [Indexed: 11/15/2022]
Abstract
Previous studies reported that new-onset persistent left bundle branch block (NOP-LBBB) was related to worse outcomes after transcatheter aortic valve implantation (TAVI). However, these results can be confounded by the presence of permanent pacemaker (PPM) implantation before and after TAVI. Long-term outcomes and the risk stratification of NOP-LBBB not having PPM implantation before and after TAVI have not been fully investigated. This is an international, multicenter, retrospective study of patients who underwent TAVI from July 31, 2007, to May 8, 2020. A total of 2,240 patients were included, and 17.5% of patients developed NOP-LBBB. NOP-LBBB was associated with cardiac mortality (adjusted hazard ratio [aHR] 1.419, 95% confidence interval [CI] 1.014 to 1.985, p = 0.041) and the composite outcomes of cardiac mortality and/or heart failure readmission (aHR 1.313, 95% CI 1.027 to 1.678, p = 0.030). Patients who developed NOP-LBBB with pre-TAVI left ventricular ejection fraction (LVEF) <40% were significantly associated with cardiac mortality (aHR 2.049, 95% CI 1.039 to 4.041, p = 0.038), heart failure (aHR 3.990, 95% CI 2.362 to 6.741, p <0.001), and the composite outcome (aHR 2.729, 95% CI 1.703 to 4.374, p <0.001). Although NOP-LBBB with pre-TAVI LVEF >40% had a significant decrease in LVEF 6 to 12 months after TAVI (-1.8 ± 9.7% vs +0.6 ± 8.1%, p = 0.003), NOP-LBBB with pre-TAVI LVEF <40% had a significant increase in LVEF 6 to 12 months after TAVI (+9.7 ± 13.6% vs +13.0 ± 11.7%, p = 0.157). In conclusion, patients with NOP-LBBB without pre-TAVI and post-TAVI PPM developed significantly worse long-term outcomes, especially in patients with pre-TAVI LVEF <40%. Further prospective investigation should be undertaken.

Transcatheter aortic valve replacement in patients with aortic stenosis and cardiac amyloidosis. IJC HEART & VASCULATURE 2022; 40:101008. [PMID: 35330979 PMCID: PMC8938882 DOI: 10.1016/j.ijcha.2022.101008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/09/2022] [Revised: 03/09/2022] [Accepted: 03/15/2022] [Indexed: 11/21/2022]
Abstract
Background Though the co-prevalence of aortic stenosis (AS) and cardiac amyloidosis (CA) is increasingly recognized, the role of transcatheter aortic valve replacement (TAVR) in patients with CA remains unclear. Methods The National Readmission Dataset (2016–18) and ICD-10 codes were used to identify those with CA and AS, in conjunction with TAVR status. The primary outcome was a composite of heart failure (HF) readmissions and all-cause mortality. All outcomes were followed up to 1-year with a median follow up time 172-days. Kaplan-Meier curves and multivariate cox-proportional hazard regression were used for time-to-event analysis. Results Of 1,127 CA patients, 92 (8.2%) had undergone TAVR. Patients with CA who received TAVR were younger and more commonly had coronary artery disease (67.3% vs 44.2%). Teaching (93.6% vs 81.1%) and large hospitals (77.7% vs 59.3%) performed more TAVRs. In multivariate analysis, TAVR was associated with an improved primary outcome (8.9% vs 24.4%, HR:0.32; 95% CI 0.14–0.71, p = 0.007) and with reduced HF readmissions (3.8% vs 19.4%, HR:0.22; 95% CI 0.07–0.68, p = 0.008). All-cause mortality was numerically lower in TAVR patients with CA but did not reach statistical significance. Conclusions CA patients who receive TAVR are younger, and the procedure is more commonly performed at large, teaching hospitals. TAVR was associated with a lower primary composite outcome of HF readmissions and all-cause mortality.

Novel Computed Tomography Angiography-Based Sizing Methodology for WATCHMAN FLX Device in Left Atrial Appendage Closure. J Cardiovasc Electrophysiol 2022; 33:1781-1787. [PMID: 35586899 DOI: 10.1111/jce.15548] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/13/2021] [Revised: 02/14/2022] [Accepted: 03/10/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND While there is recent data suggesting an advantage of Computed Tomography Angiography (CTA) over transesophageal echocardiography (TEE) for pre-procedural left atrial appendage closure (LAAC) planning, there is limited published experience for sizing strategies. Device sizing for LAAC may be challenging and non-invasive algorithms that improve this selection process are warranted. OBJECTIVES We sought to evaluate the safety and the feasibility for the implementation of a novel CTA-based sizing methodology for WATCHMAN™ FLX device in a series of patients undergoing LAAC using the TruPlan™ software package. METHODS A prospective analysis of 136 consecutive patients who underwent LAAC over a 12-month period in a single, large academic hospital in the United States was conducted. CTA-guided pre-procedural planning and intracardiac echocardiography (ICE) was performed in all. Procedural success, adverse events, length of procedure, number of devices used, and length of stay were evaluated. RESULTS A total of 136 patients who underwent LAAC procedure with WATCHMAN™ FLX platform between October 1, 2020 until September 30, 2021 were included. The pre-specified protocol using CTA and ICE was implemented in all patients (100%). Mean CHA2 DS2 VASc score was 4.4 ± 1.3 and the mean HAS-BLED score was 3.9 ± 0.8. ICE-guided 100% transseptal puncture success rate was 100% with 98.5% of overall procedural success rate. Pre-procedural CTA sizing strategy accurately predicted the implanted size in 91.1% of patients. Ten patients (7.4%) required another sized device and 2 cases were aborted. At 45-day follow-up, only 1 patient (0.7%) had significant peri-device leak (≥ 5mm) on TEE. CONCLUSIONS CTA-based pre-procedural sizing methodology for WATCHMAN™ FLX in LAAC was safe, feasible and associated with excellent procedural outcomes. Further studies are warranted to confirm if the features specific to TruPlan™ may reduce the number of deployment attempts, the number of devices utilized in the procedure, and the risk of complications.

Abstract
BACKGROUND Percutaneous left atrial appendage occlusion (LAAO) with the Watchman device is FDA approved for stroke prevention in patients with nonvalvular atrial fibrillation who have an appropriate indication. During the COVID-19 pandemic, a same-day discharge protocol (SDDP) was employed to improve resource utilization, relieve hospital occupation, and reduce the possible risk of in-hospital virus transmission. OBJECTIVES We sought to analyze the safety, feasibility, and cost effectiveness for SDDP in patients receiving LAAO. METHODS A prospective analysis of 142 consecutive patients, 119 treated prior to SDDP and 23 who underwent SDDP following LAAO with cardiac computed tomography angiography (CTA)-guided pre-procedural planning and intracardiac echocardiogram (ICE). Procedures were performed in a single, large academic hospital in the United States. In-hospital and 45-day procedural success, adverse events, length of procedure, and length-of-stay were evaluated. RESULTS Baseline patient characteristics including mean CHA2DS2VASc scores and mean HAS-BLED scores were similar in both groups. All procedures were successful. There was no significant difference in rates of procedural complications or in-hospital adverse events. The mean procedure time in the SDDP group was 11 minutes longer than in the conventional group (62.1 ± 5.9 vs 51.1 ± 21; P=.01). Outcomes at 45-day follow-up were similar. SDDP was associated with a reduced length of stay compared with conventional strategy and a 15% reduction in total costs. CONCLUSIONS Same-day discharge strategy for LAAO appears safe, feasible and could become the new standard approach for LAAO. A protocol including CTA pre-procedural planning, ICE-guided deployment and conscious sedation reduces hospital occupation and lowers costs.

Abstract
OBJECTIVES We reviewed the periprocedural events, accuracy of device selection, and outcomes of a series of patients receiving percutaneous left atrial appendage occlusion (LAAO) with cardiac computed tomography angiography (CTA)-guided preprocedural planning and intracardiac echocardiography (ICE)-guided device deployment. BACKGROUND Percutaneous LAAO with the Watchman device (Boston Scientific) is approved by the United States Food and Drug Administration for stroke prevention in patients with non-valvular atrial fibrillation with a demonstrated contraindication to oral anticoagulation. Cardiac CTA preprocedural planning with utilization of an ICE-guided deployment may be associated with favorable outcomes. METHODS A prospective analysis of 71 non-consecutive patients who underwent LAAO over an 18-month period with cardiac CTA-guided preprocedural planning and ICE was conducted. Procedures were performed in a single large, academic hospital in the United States. Procedural success, correlation of CTA preprocedural device sizing with final device size utilization, adverse events, length of procedure, and length of stay were evaluated. RESULTS Preprocedural cardiac CTA-guided device sizing was consistent with the final deployed device in 69 patients (97.2%) evaluated in this case series. Procedure success rate was 100%. All implants were performed using Watchman devices, 45 (63.4%) with the original 2.5 platform and 26 (36.6%) with the Watchman FLX platform. All patients were treated with conscious sedation and the mean length of stay was 1.45 ± 0.72 days. Only 2 adverse events occurred and both resolved. CONCLUSIONS Cardiac CTA-guided preprocedural planning resulted in accurate device sizing in this patient sample and may be used in conjunction with ICE and conscious sedation for a same-day discharge strategy in select patients.

Abstract
Pseudoaneurysm of the ascending aorta is a rare complication of cardiac surgery due to tissue degeneration at the site of graft anastomosis, aortotomy, or extracorporeal circulation cannulation. We describe the case of a patient who developed an ascending aorta pseudoaneurysm after coronary artery bypass graft surgery, which initially required percutaneous closure with an atrial septal defect occlusion device. However, three years later the patient presented again with active external bleeding secondary to pseudoaneurysm enlargement and rupture, which was emergently repaired by percutaneous endovascular repair with a thoracic aortic stent graft. At one-year follow-up the patient is in good conditions and asymptomatic.

Abstract
INTRODUCTION The presence of mild to moderate pericardial effusion after cardiac surgery is common and oral medical therapy is usually able to treat it. Larger effusions are less frequent and surgical intervention is usually necessary. However, there are some rare cases of large effusions that are recurrent even after intervention and become challenging to treat. METHODS We describe the case of a patient submitted to coronary artery bypass grafting (CABG) without any intraoperative complications, who was regularly discharged from the hospital. She was referred to our emergency department twice after surgery with large pericardial effusion that was drained. Even after those two interventions and with adequate oral medication, the large effusion recurred. RESULTS During follow-up, the patient had her symptoms resolved, with no need for further hospital admission. Her echocardiograms after the last intervention showed no pericardial effusion. The present surgical technique demonstrated to be easy to perform, thus it should be considered as a treatment option for these rare cases of large and repetitive effusions, which do not respond to the traditional methods. CONCLUSIONS In challenging cases of recurrent and large pericardial effusions, the pericardial-peritoneal window is an alternative surgical technique that brings clinical improvement and diminishes the risk of cardiac tamponade.

Abstract
We developed a fully automated, two-step deep learning approach for characterizing coronary calcified plaque in intravascular optical coherence tomography (IVOCT) images. First, major calcification lesions were detected from an entire pullback using a 3D convolutional neural network (CNN). Second, a SegNet deep learning model with the Tversky loss function was used to segment calcified plaques in the major calcification lesions. The fully connected conditional random field and the frame interpolation of the missing calcification frames were used to reduce classification errors. We trained/tested the networks on a large dataset comprising 8,231 clinical images from 68 patients with 68 vessels and 4,320 ex vivo cadaveric images from 4 hearts with 4 vessels. The 3D CNN model detected major calcifications with high sensitivity (97.7%), specificity (87.7%), and F1 score (0.922). Compared to the standard one-step approach, our two-step deep learning approach significantly improved sensitivity (from 77.5% to 86.2%), precision (from 73.5% to 75.8%), and F1 score (from 0.749 to 0.781). We investigated segmentation performance for varying numbers of training samples; at least 3,900 images were required to obtain stable segmentation results. We also found very small differences in calcification attributes (e.g., angle, thickness, and depth) and identical calcium scores on repetitive pullbacks, indicating excellent reproducibility. Applied to new clinical pullbacks, our method has implications for real-time treatment planning and imaging research.

Feasibility of coronary angiogram-derived vessel fractional flow reserve in the setting of standard of care percutaneous coronary intervention and its correlation with invasive FFR. Int J Cardiol 2019; 301:45-49.

Abstract
BACKGROUND Vessel Fractional Flow Reserve (vFFR), a new angiography-derived method for the functional assessment of coronaries, was recently shown to have good correlation with invasive wire-derived FFR, when vFFR-specific image acquisition requirements were followed. We sought to investigate the feasibility of vFFR analysis and its correlation with FFR in the situation where angiography is completed in routine fashion, without intention for virtual analysis. METHODS Utilizing an anonymized database maintained at our Cardiovascular Imaging Core Laboratory, we included angiographic images from patients that underwent pre- and post-PCI FFR. CAAS Workstation 8.1 software (Pie Medical Imaging) was used for vFFR evaluation. RESULTS Out of 624 angiograms (312 pre-PCI and 312 post-PCI), vFFR was successfully analyzed in 219 (35.1%) (115 pre-PCI and 104 post-PCI). Reasons for vFFR analysis failure were: <2 angiographic projections (42.5%), table movement while acquisition (25.7%) and resolution incompatibility (15%). From 115 patients with analyzable pre-PCI vFFR, 74 (64.3%) showed agreement with the respective FFR results in terms of positive (≤0.80) vs negative (>0.80) FFR. Pearson's correlation coefficient between them was 0.449 (p < 0.0001). From 104 lesions with analyzable post-PCI vFFR, 94 had availability of FFR, 74 (78.7%) of which showed agreement between the vFFR and FFR. Pearson's correlation between the values was 0.115 (p = 0.2703). CONCLUSION vFFR could be analyzed in about one-third of previously completed angiographies and a weak correlation was seen between vFFR and FFR. Our results show the importance of following the pre-specified requirements for vFFR analysis. Further studies are needed to validate the software in different settings.

Abstract
We describe an interesting case of a 71 years old fragile female, with progressive shortness of breath on exertion and ankle swelling, cardiac failure NYHA class III. She also had chest irradiation due to Hodgkin's disease many years before, previous surgical aortic valve replacement using bioprosthetic stent-less Freestyle #25 mm valve (Medtronic, Inc) in 2000 for severe aortic stenosis, history of cardiac arrest in 2012 and angioplasty to ostial RCA, PCI to ostial RCA in 2014, CABG (RA graft to RCA) in 2014 (RCA intra-stent restenosis with refractory ischemia), anemia requiring regular transfusions, bronchiectasis and chronic kidney disease. Because of the great comorbidities, STS 4.9% and worsening of the symptoms due to severe aortic valve regurgitation, heart team decided to perform "valve-in-valve" Transcatheter Aortic Valve Replacement (VIV-TAVR), but we already predicted coronary occlusion while performing this procedure because of the low left main coronary ostium and short aortic valve sinus. So regarding the probable left main coronary occlusion during the valve implantation, we decided to perform the placement of a not deployed stent inside the left main prior to the valve procedure, and to deploy it in case the predicted left main occlusion occurred. So just after the VIV-TAVR procedure, we observed left main coronary occlusion and the patient got ischemic cardiogenic shock and cardiac arrest, so we performed immediate PCI and deployed the bailout stent. After some minutes of chest compressions, an Impella mechanical circulatory support system (Abiomed, Danvers, MA) had to be installed. Patient recovered spontaneous circulation, and after hemodynamic stabilization, she was sent to the Intensive Coronary Unit, without further complications. She was discharged successfully without neurological or cardiac sequelae after 1 week.

Abstract
Patients with heart failure who have secondary severe mitral regurgitation due to left ventricular dysfunction have a poor prognosis, with high rates of rehospitalization and mortality. Percutaneous mitral valve repair using the MitraClip (Abbott) has been shown to be safe and effective in secondary severe mitral regurgitation with heart failure. The number of MitraClip procedures performed has increased significantly, as recently published large, randomized clinical studies have shown. However, these studies have drawn different conclusions. This review aims to summarize the current evidence for the MitraClip procedure and provide information for its safe and successful implementation, comparing the studies that examined the use of MitraClip versus medical therapy alone or surgical repair for severe secondary mitral regurgitation.
