Background Histology of thrombosis events in left ventricular assist devices (LVADs) may point to differences between the etiology of either ingested or de novo thrombus formation within LVADs. Materials ingested by the pump would have features sugge

New left ventricular assist devices (LVADs) offer both important advantages and potential hazards. VAD development requires better and expeditious ways to identify these advantages and hazards. We validated in an isolated working heart the hemodynami

Controller algorithms are an important feature for assessment of ventricular assist device performance. Flow estimation is one algorithm implemented in the HeartWare continuous-flow ventricular assist device pump system. This parameter estimates flow

Objective Ventricular assist device (VAD) miniaturization is one design trend that may result in less-invasive implantation techniques and more versatility with patient selection. The MVAD System is a miniature, continuous-flow device implanted in th

Implantation of ventricular assist devices (VADs) for the treatment of end-stage heart failure (HF) falls decidedly short of clinical demand, which exceeds 100,000 HF patients per year. Ventricular assist device implantation often requires major surg

In an ovine feasibility study, we implanted two HeartMate-III centrifugal ventricular assist devices (VADs) for total heart replacement. With cardiopulmonary bypass support, both ventricles were transected at the atrioventricular groove, preserving a

The Jarvik 2000 ventricular assist device (VAD) is clinically efficacious for treating end-stage left ventricular failure. Because simultaneous right ventricular support is also occasionally necessary, we developed a biventricular Jarvik 2000 techniq

Patients with congestive heart failure who are supported with a left ventricular assist device (LVAD) may experience right ventricular dysfunction or failure that requires support with a right ventricular assist device (RVAD). To determine the feasib

HeartWare continuous flow ventricular assist devices (HVAD) configured as biventricular assist devices maintain diurnal flow variation, lead to end-organ recovery, and provide for a successful bridge-to-heart transplantation in the first successful N

As a result of stagnant heart transplantation rates, ventricular assist devices (VADs) have become a widely accepted therapy for the treatment of advanced-stage heart failure. Long-term reliability of VADs will become increasingly vital as the popula
