The Jarvik 2000 left ventricular assist device as a bridge to transplantation: Japanese Registry for Mechanically Assisted Circulatory Support

Mid-term survival after Jarvik 2000 implantation was satisfactory and comparable to that reported by other national and international registries (INTERMACS and IMACS) for continuous-flow LVADs. De novo aortic regurgitation occurred despite the intermittent low-speed effect of this device, with some recipients experiencing progressive worsening of aortic regurgitation within 2 years post-implantation.
