Patients coming to open heart surgery with advanced cardiac dysfunction may require mechanical cardiac support to avoid life-threatening low cardiac output in the postoperative period. 15 patients who could not be withdrawn from cardiopulmonary bypass because of low cardiac output were supported with a left heart bypass system (left atrium to ascending aorta). Ten were ultimately separated from the device, 6 were dismissed from the hospital and 4 remain well (the longest 2.6 years postoperative). A major asset of the device is that thoracic reentry is not required when support is discontinued.
患有晚期心脏功能障碍并接受心脏直视手术的患者可能需要机械心脏支持，以避免术后出现危及生命的低心输出量情况。15名因低心输出量而无法脱离体外循环的患者接受了左心旁路系统（左心房至升主动脉）的支持。其中10人最终脱离了该装置，6人出院，4人情况良好（术后最长2.6年）。该装置的一个主要优点是，在停止支持时不需要再次打开胸腔。
