Comparison of short- and long-term outcomes between isolated and concomitant tricuspid valve surgery

Background Accurate reflections of long-term outcomes of isolated tricuspid valve surgery are underreported in the literature. Most published cohort studies consisted of patients receiving tricuspid valve surgery concomitant with left-sided procedures. Patients who undergo isolated tricuspid valve surgery usually present late for surgery, with deteriorating risk factors leading to increased surgical risk. Thus, this study aimed to compare the short- and long-term outcomes of isolated tricuspid valve surgery with those of tricuspid surgery concomitant with left-sided valve procedures. This retrospective cohort study included 617 patients who underwent isolated and left-sided concomitant tricuspid valve surgery from 2009 to 2020. We grouped the patients into isolated ( n = 63) vs. concomitant tricuspid surgery ( n = 554). Results Isolated tricuspid surgery was associated with significantly greater rates of operative mortality (19% vs. 5.2%, P
