RESUMEN
INTRODUCTION: We studied the effect of tricuspid valve (TV) surgery combined with surgical ventricular restoration (SVR) on operative outcomes, rehospitalization, recurrent tricuspid regurgitation, and survival of patients with ischemic cardiomyopathy. Additionally, surgery was compared to conservative management in patients with mild or moderate tricuspid regurgitation. To the best of our knowledge, the advantage of combining TV surgery with SVR in patients with ischemic cardiomyopathy had not been investigated before. METHODS: This retrospective cohort study included 137 SVR patients who were recruited from 2009 to 2020. Patients were divided into two groups - those with no concomitant TV surgery (n=74) and those with concomitant TV repair or replacement (n=63). RESULTS: Extracorporeal membrane oxygenation use was higher in SVR patients without TV surgery (P=0.015). Re-exploration and blood transfusion were significantly higher in those with TV surgery (P=0.048 and P=0.037, respectively). Hospital mortality occurred in eight (10.81%) patients with no TV surgery vs. five (7.94%) in the TV surgery group (P=0.771). Neither rehospitalization (log-rank P=0.749) nor survival (log-rank P=0.515) differed in patients with mild and moderate tricuspid regurgitation in both groups. Freedom from recurrent tricuspid regurgitation was non-significantly higher in mild and moderate tricuspid regurgitation patients with no TV surgery (P=0.059). Conservative management predicted the recurrence of tricuspid regurgitation. CONCLUSION: TV surgery concomitant with SVR could reduce the recurrence of tricuspid regurgitation; however, its effect on the clinical outcomes of rehospitalization and survival was not evident. The same effects were observed in patients with mild and moderate tricuspid regurgitation.

ABSTRACT Introduction: Bleeding after transcatheter aortic valve replacement (TAVR) is associated with increased mortality. The predictive value of the HAS-BLED score in TAVR patients is still to be evaluated. We assessed the value of the HAS-BLED score to predict in-hospital bleeding and mortality after TAVR and the impact of diferent renal impairment definitions on the predictive value of the score system. Methods: We retrospectively included 574 patients who underwent TAVR at a single center. Study outcomes were 30-day mortality and the composite endpoint of major and life-threatening bleeding as defined by The Valve Academic Research Consortium-2. The predictive value of the HAS-BLED score was calculated and compared to a modified model. The performance of the score was compared using two definitions of renal impairment. Model discrimination was tested using C-statistic and the Net Reclassification Index. Results: Bleeding occurred in 78 patients (13.59%). HAS-BLED category 3 was a significant predictor of bleeding (OR: 1.99 ]1.18- 3.37], C-index: 0.56, P=0.01). C-index increased to 0.64 after adding body surface area and extracardiac arteriopathy to the model. The Net Reclassification Index showed an increase in the predic tive value of the model by 11.4% (P=0.002). The C-index increased to 0.61 using renal impairment definition based on creatinine clearance. Operative mortality was significantly associated with the HAS-BLED score (OR: 7.54 [95% CI: 2.73- 20.82], C-index: 0.73, P<0.001). Conclusion: The HAS-BLED score could be a good predictor of in-hospital mortality after TAVR. Its predictive value for bleeding was poor but improved by adding procedure-specific factors and using creatinine clearance to define renal impairment.
RESUMEN
ABSTRACT Introduction: Repeat transcatheter mitral valve replacement (rTMVR) has emerged as a new option for the management of high-risk patients unsuitable for repeat surgical mitral valve replacement (rSMVR). The aim of this study was to compare hospital outcomes, survival, and reoperations after rTMVR versus surgical mitral valve replacement. Methods: We compared patients who underwent rTMVR (n=22) from 2017 to 2019 (Group 1) to patients who underwent rSMVR (n=98) with or without tricuspid valve surgery from 2009 to 2019 (Group 2). We excluded patients who underwent a concomitant transcatheter aortic valve replacement or other concomitant surgery. Results: Patients in Group 1 were significantly older (72.5 [67-78] vs. 57 [52-64] years, P<0.001). There was no diference in EuroSCORE II between groups (6.56 [5.47-8.04] vs. 6.74 [4.28-11.84], P=0.86). Implanted valve size was 26 (26-29) mm in Group 1 and 25 (25-27) mm in Group 2 (P=0.106). There was no diference in operative mortality between groups (P=0.46). However, intensive care unit (ICU) and hospital stays were shorter in Group 1 (P=0.03 and <0.001, respectively). NYHA class improved significantly in both groups at one year (P<0.001 for both groups). There was no group effect on survival (P=0.84) or cardiac readmission (P=0.26). However, reoperations were more frequent in Group 1 (P=0.01). Conclusion: Transcatheter mitral valve-in-valve could shorten ICU and hospital stay compared to rSMVR with a comparable mortality rate. rTMVR is a safe procedure; however, it has a higher risk of reoperation. rTMVR can be an option in selected high-risk patients.

RESUMEN
Abstract Introduction: Bleeding after transcatheter aortic valve replacement (TAVR) has a negative impact on the outcome of the procedure. Risk factors for bleeding vary widely in the literature, and the impact of preoperative antithrombotic agents has not been fully established. The objectives of our study were to assess bleeding after TAVR as defined by the Valve Academic Research Consortium-2 (VARC-2), identify its risk factors, and correlate with antithrombotic treatment in addition to its effect on procedural mortality. Methods: The study included 374 patients who underwent TAVR from 2009 to 2018. We grouped the patients into four groups according to the VARC-2 definition of bleeding. Group 1 included patients without bleeding (n=265), group 2 with minor bleeding (n=22), group 3 with major bleeding (n=61), and group 4 with life-threatening bleeding (n=26). The median age was 78 (25th-75th percentiles: 71-82), and 226 (60.4%) were male. The median EuroSCORE was 3.4 (2-6.3), and there was no difference among groups (P=0.886). The TAVR approach was transfemoral (90.9%), transapical (5.6%), and trans-subclavian (1.9%). Results: Predictors of bleeding were stroke (OR: 2.465; P=0.024) and kidney failure (OR: 2.060; P=0.046). Preoperative single and dual antiplatelet therapy did not increase the risk of bleeding (P=0.163 and 0.1, respectively). Thirty-day mortality occurred in 14 patients (3.7%), and was significantly higher in patients with life-threatening bleeding (n=8 [30.8%]; P<0.001). Conclusion: Bleeding after TAVR is common and can be predicted based on preprocedural comorbidities. Preprocedural antithrombotic therapy did not affect bleeding after TAVR in our population.
