    Abstract:
    There is limited clinical evidence on when to address tricuspid regurgitation in patients with aortic and mitral valve disease requiring surgical intervention. In this study, we aimed to investigate the potential added value of performing a tricuspid valve repair concomitantly in patients requiring double valve surgery (DVS) of the aortic and mitral valves. We reviewed 223 cases of multivalve surgery from 2011 to 2016. In this single-institution series, 190 underwent DVS in aortic and mitral positions and 33 had triple valve surgery in aortic, mitral, and tricuspid positions. Preoperative and postoperative echocardiograms were evaluated to determine changes in valve function. A logistic regression model was performed to assess relationship of patient comorbidities and type of valve operations to perioperative adverse events. Mid-term survival was similar between the 2 groups (P = 0.541). Compared to DVS, TVS was not associated with an increased risk of perioperative adverse events, including need for pacemaker or mortality on multivariable analysis. Within the DVS subgroup, 19.8% of patients experienced improvement in tricuspid valve function with decrease in the degree of tricuspid regurgitation within a 6-month postoperative follow-up. Our study indicates that repairing the tricuspid valve while addressing the aortic and mitral valves does not pose significant additional risk. The observed improvement of the degree of tricuspid regurgitation without tricuspid operation suggests the need to further define subpopulations of patients with multivalvular disease.
