RESUMO
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: 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.
