Left ventricular assist device implantation with and without concomitant tricuspid valve surgery: A systematic review and meta-analysis
OBJECTIVES Moderate-to-severe tricuspid regurgitation is common in end-stage heart disease and is associated with an impaired survival after left ventricular assist device (LVAD) surgery. Controversy remains whether concomitant tricuspid valve surgery (TVS) during LVAD implantation is beneficial. We aimed to provide a contemporary overview of outcomes in patients who underwent LVAD surgery with or without concomitant TVS. METHODS A systematic literature search was performed for articles published between January 2005 and March 2017. Studies comparing patients undergoing isolated LVAD implantation and LVAD + TVS were included. Early outcomes were pooled in risk ratios using random effects models, and late survival was visualized by a pooled Kaplan-Meier curve. RESULTS Eight publications were included in the meta-analysis, including 562 undergoing isolated LVAD implantation and 303 patients with LVAD + TVS. Patients undergoing LVAD + TVS had a higher tricuspid regurgitation grade, central venous pressure and bilirubin levels at baseline and were more often female. We found no significant differences in early mortality and late mortality, early right ventricular failure and late right ventricular failure, acute kidney failure, early right ventricular assist device implantation or length of hospital stay. Cardiopulmonary bypass time was longer in patients undergoing additional TVS [mean difference +35 min 95% confidence interval (16-55), P = 0.001]. CONCLUSIONS Adding TVS during LVAD implantation is not associated with worse outcome. Adding TVS, nevertheless, may be beneficial, as baseline characteristics of patients undergoing LVAD + TVS were suggestive of a more progressive underlying disease, but with comparable short-term outcome and long-term outcome with patients undergoing isolated LVAD.
