Abstract
Introduction: Continuous-flow left ventricular assist devices (LVADs) augment cardiac output without the degree of left ventricular decompression and septal shift seen with pulsatile LVADs. Rotor speed is adjusted based on hemodynamic, echocardiographic and clinical data to optimize output and ventricular interaction. For these reasons, we theorized that the incidence of right ventricular dysfunction (RVD) may be reduced in patients implanted with continuous-flow LVADs. Methods: We retrospectively compared the incidence of RVD in patients implanted with pulsatile (Thoratec, Novacor or Heartmate XVE) and continuous-flow (Jarvik, Ventrassist or Heartmate II) LVADs.
