      Abstract

      Introduction

      Isolated tricuspid valve (TV) surgery is uncommonly performed and has historically been associated with excessive operative mortality. We previously reported improved short-term outcomes at our center. Understanding contemporary outcomes of isolated TV surgery beyond the perioperative period is essential to properly benchmark outcomes of newer transcatheter interventions.

      Methods

      Patients who underwent isolated TV surgery from 2007 to 2021 at a single institution were retrospectively reviewed. Survival was estimated using the Kaplan–Meier method and multivariable Cox proportional hazards regression modeling identified independent risk factors for all-cause mortality.

      Results

      Among 173 patients undergoing isolated TV surgery, 103 (60%) underwent TV repair and 70 (40%) underwent TV replacement. Mean age was 60.3 ± 18.9 y and 55 (32%) were male. The most common etiology of TV disease was functional (46%). In-hospital mortality was 4.1% (7/173), with no difference between TV repair and replacement (P = 0.06). Overall survival at 1 y and 5 y was 78.3% (111/142) and 64.5% (53/82), respectively. After median (interquartile range) follow-up of 2.0 (0.6-4.4) y, patients undergoing TV repair experienced a higher unadjusted survival as compared to those undergoing TV replacement (log-rank P = 0.02). However, after adjusting for covariates, TV replacement was not an independent predictor of all-cause mortality (hazard ratio 1.40; 95% confidence interval, 0.71-2.76; P = 0.33).

      Conclusions

      Isolated TV surgery can be performed with lower operative mortality than historically reported. Establishing survival benchmarks from TV surgery is important in the era of developing transcatheter interventions.
