Blood flow in a double output centrifugal artificial heart pump as a biventricular assist device

Recent results show that left ventricular assist devices can extend patient’s lives, but may cause right heart failure syndrome; consequently, these patients require a right ventricular assist device. Therefore, biventricular assist device implantation is recommended for long term use. Current development of a biVentricular Assist Device consists of left and right chambers housed in a single unit with dierent chamber capacity to cater for the dierential pressure in left and right outputs. This article proposes a novel biventricular assist device design and estimates the leakage ow. To identify the leakage ow in a
