HeartWare miniaturized intrapericardial ventricular assist device: advantages and adverse events in comparison to contemporary devices.

Increasing incidence of end-stage heart failure and limited availability of donor organs have led to longer waiting times for cardiac transplantation and subsequently increasing mortality. Ventricular assist device therapy is fast becoming an accepted alternative treatment to treat end-stage heart failure and is being implemented as a bridge to decision, bridge to myocardial recovery, bridge to heart transplantation or as a destination therapy. LVADs not only enable hemodynamic stabilization and recovery of secondary organ failure in severely ill patients, but have also been shown to reduce pulmonary vascular resistance in nontransplantable candidates. Technology of ventricular assist devices has evolved over several decades of time and generations of devices. The HVAD® Pump (HeartWare International, Inc., MA, USA) is a third-generation, miniaturized, continuous-flow ventricular assist device. Due to its miniaturized housing and intrapericardial placing, it can be used proficiently to support the right ventricle and has also demonstrated great utility in minimally invasive and off-pump implantation, exchange and explantation. It is favored for similar reasons in adolescents and in heart failure due to complex congenital heart disease. The purpose of this article is to review the clinical use of HeartWare® Ventricular Assist System (HeartWare System; HeartWare International, Inc.) with different strategies pertaining to its advantages and adverse events in comparison with contemporary devices.
