The ReliantHeart aVAD© is a new intraventricular axial flow pump with pumping components that fit within the inflow cannula of the ventricular assist device (VAD). The aVAD© is an improvement over its predecessor, the extra-ventricular HeartAssist5 (HA5)™. The pumping components, inflow guide vane, impeller, and diffuser of the aVAD© are identical to those in the HA5, which in turn were derived from the original collaboration between Baylor College of Medicine and NASA. The current device provides excellent physiologic support for patients in end-stage heart failure and provides advanced ultrasonic flow measurements and performance data for wireless remote monitoring. In 2011 and 2012, the aVAD© was used successfully in calf studies as an artificial heart, with each ventricle being replaced by a modified HA5 VAD©. The two predecessor aVADs© were placed vertically, side by side, which provided a more compact total artificial heart with formable outflow graft protectors directed to the aorta and pulmonary artery. An ultrasonic flow probe accurately measures flow under all conditions, even in implants in place for years. The probe indicates flow in the range of –4 to +10 L/min with >95% accuracy. The probe can determine the relative contributions of the LVAD and native heart to adequate blood flow. The aVAD© meets the safety standards of the European Union and is sold in Europe. The aVAD is not yet available in the United States but is being tested under an FDA investigational device exemption.
