The purpose of this study was to evaluate gender differences regarding outcome after continuous-flow left ventricular assist device (cfLVAD) implantation. The study was a retrospective review of prospectively collected data. Included were 24 consecutive female cfLVAD recipients and 24 male recipients (62.5% HeartMate II, 37.5% HeartWare) who received their devices between July 2007 and May 2013. ⋯ Half (50%) of female recipients required short-term postoperative right ventricular assist device implantation compared with 16.7% in the male group (P < 0.014). In conclusion, cfLVAD implantation as a bridge to transplantation is associated with longer duration of inotropic support and higher requirement for postoperative mechanical right ventricular support in women with similar survival rates. Further studies are required to identify additional demographic and clinical factors that modulate outcomes and will enhance the ability to risk-stratify cfLVAD recipients.
