Objective: The choice to operate on moderate tricuspid regurgitation (TR) during mitral surgery is challenging owing to limited mid-term data. We assess whether concomitant tricuspid operations improve mid-term quality of life, morbidity, or mortality. Methods: An institutional database identified mitral surgery recipients with moderate TR at the time of surgery from 2010 to 2019. Patients were stratified by the presence of a concomitant tricuspid operation. Quality of life at the last follow-up was assessed with the Kansas City Cardiomyopathy Questionnaire (KCCQ-12). Morbidity was compared using the χ2 test, Mann-Whitney U test, and Student t test. Survival was analyzed with Kaplan-Meier estimation. Results: Of 210 mitral surgery recipients, 67 (31.9%) underwent concomitant tricuspid surgery. The concomitant tricuspid surgery cohort had greater preoperative dialysis use (10.5% vs 3.5%; P = .043) but similar age, New York Heart Association class, and cardiac surgery history relative to the nonconcomitant cohort (P > .05 for all). The concomitant tricuspid surgery cohort had a longer cardiopulmonary bypass time (144 minutes vs 122 minutes; P = .005) but a similar rate of mitral repair (P = .220). Postoperative KCCQ-12 scores reflected high quality of life in both cohorts (95.1 vs 89.1; P = .167). The concomitant tricuspid surgery cohort trended toward a higher perioperative pacemaker placement rate (22.8% vs 12.7%; P = .088) but were less likely to develop severe TR (0.0% vs 13.0%; P = .004). Overall survival was comparable between the 2 cohorts at 1 year (84.9% vs 81.6%; P = .628) and 5 years (73.5% vs 57.9%; P = .078). Five-year survival free from severe TR was higher in the concomitant cohort (73.5% vs 54.3%; P = .032). Conclusions: Concomitant tricuspid surgery for moderate TR is associated with increased 5-year survival free from severe TR but not with increased quality of life.
