Hemodynamic Performance In-Vivo of a New Ventricular Assist Device

Nowadays, circulatory support has become a common practice in medicine and a standard in the treatments of cardio vascular disease (CVD). A new pneumatic ventricular assist device (VAD) has been developed in Mexico City. This paper shows the first results of acute in-vivo trials, intended to verify the new system for providing physiological flows and pressures. Two VADs were implanted to as right (RVAD), left (LVAD) support in a 65 kg pig. The support time was 20 minutes with RVAD, 20 minutes with LVAD and 20 minutes with biventricular (BiVAD). The VAD proved its capability to maintain physiological parameters during the support time. We are satisfied with the results of this trial, and we believe this study will ascertain the first step on the next phase of in-vivo trials
