Abstract
The outcomes of ventricular assist device therapy remain limited by right ventricular failure. We sought to define the predictors and evaluate the outcomes of right ventricular failure requiring right ventricular assist device support after long-term continuous-flow left ventricular assist device implantation. Records of all continuous-flow left ventricular assist device recipients for the last 10 years were analyzed, including patients on preoperative intra-aortic balloon pump, extracorporeal membrane oxygenation, and short-term ventricular assist device support. Perioperative clinical, echocardiographic, hemodynamic, and laboratory data of continuous-flow left ventricular assist device recipients requiring right ventricular assist device support (right ventricular assist device group) were compared with the rest of the patient cohort (control group). Between July 2003 and June 2013, 152 patients underwent continuous-flow left ventricular assist device implantation as a bridge to transplantation. The overall postoperative incidence of right ventricular assist device support was 23.02% (n = 35). Right ventricular assist device implantation did not significantly affect eventual transplantation (P = .784) or longer-term survival ...Continue Reading
