Partial artificial heart (ALVAD) use with subsequent cardiac and renal allografting in a patient with stone heart syndrome.

abstract：:Left dominant biventricular failure is a common type of heart failure after cardiac surgery. We developed a biventricular bypass (BVB) system for treatment of postcardiotomy ventricular failure, and we previously reported that the clinical results of the BVB system were superior to those obtained with venoarterial byp...
