Concomitant Tricuspid Valve Surgery Is Not Associated With Increased Operative Risk During Robotic Mitral Valve Surgery

Objective: The aim of this study was to investigate the outcomes of robotic mitral valve surgery with and without concomitant tricuspid valve surgery. Methods: Patients who underwent robotic mitral surgery between March 2010 and September 2022 were included. Patients were grouped according to the presence of concomitant tricuspid interventions. The groups were compared for baseline factors, operative parameters, and early postoperative outcomes. Age- and gender-matched groups were also compared for outcomes. Results: The study included 285 robotic mitral surgery patients. There were 59 patients who underwent concomitant tricuspid interventions. In the concomitant tricuspid surgery group, cardiopulmonary bypass time (150.1 vs 128.4 min, P < 0.001) and cross-clamp time (99.2 vs 82.4 min, P < 0.001) were longer. Prolonged intubation was more frequent in the concomitant tricuspid intervention group (5.2% vs 0.5%, P = 0.029). The groups did not differ in terms of mortality, permanent pacemaker (PPM) requirement, or other morbidities. Perioperative outcomes were similar after matched group analysis. Conclusions: Operative mortality and early adverse outcomes did not increase with the addition of tricuspid intervention in our cohort of robotic mitral surgery patients. The robotic approach for mitral disease and coexisting tricuspid disease may offer safe results without an increased risk of postoperative PPM requirement.
