A case of late-onset right ventricular failure after implantation of a continuous-flow left ventricular assist device.

Postoperative right ventricular failure is usually apparent perioperatively or soon after left ventricular assist device insertion. Here, we report a case complicated by right ventricular failure that manifested 3 weeks after HeartMate II implantation. This case is also unique because the postoperative right ventricular failure was progressive over the years. We discuss how the smaller size of the left ventricle and untreated tricuspid regurgitation contributed to the development of right ventricular failure in this case.
