Abstrakt: Background: Significant tricuspid regurgitation (TR) is a predictor of right heart failure (RHF) and increased mortality following left ventricular assist device (LVAD) implantation, however the benefit of tricuspid valve surgery (TVS) at the time of LVAD implantation remains unclear. This study compares early and late mortality and RHF outcomes in patients with significant TR undergoing LVAD implantation with and without concomitant TVS.
Methods: A systematic search of four electronic databases was conducted for studies comparing patients with moderate or severe TR undergoing LVAD implantation with or without concomitant TVS. Meta-analysis was performed for primary outcomes of early and late mortality and RHF. Secondary outcomes included rate of stroke, renal failure, hospital and ICU length of stay. An overall survival curve was constructed using aggregated, reconstructed individual patient data from Kaplan-Meier (KM) curves.
Results: Nine studies included 575 patients that underwent isolated LVAD and 308 patients whom received concomitant TVS. Both groups had similar rates of severe TR (46.5% vs. 45.6%). There was no significant difference seen in risk of early mortality (RR 0.90; 95% CI, 0.57-1.42; p = 0.64; I 2  = 0%) or early RHF (RR 0.82; 95% CI, 0.66-1.19; p = 0.41; I 2  = 57) and late outcomes remained comparable between both groups. The aggregated KM curve showed isolated LVAD to be associated with overall increased survival (HR 1.42; 95% CI, 1.05-1.93; p = 0.023).
Conclusions: Undergoing concomitant TVS did not display increased benefit in terms of early or late mortality and RHF in patients with preoperative significant TR. Further data to evaluate the benefit of concomitant TVS stratified by TR severity or by other predictors of RHF will be beneficial.
