Total artificial heart without valves: principles of design and implantation technique

A total artificial heart (TAH) without valves is a TAH of a new design. The entry and exit are combined in one opening. The excision of the biologic ventricles is below the atrioventricular groove, while the outlet and position of the right and left ventricles are preserved. The aortic and pulmonary valves have been left intact. Bioprostheses BAKS are implanted into the mitral and tricuspidal positions. Initial experiments hold much promise: the absence of artificial valves decreases the risk of thromboemboly; the natural heart basis remains intact, which facilitates the subsequent donor heart transplantation; and the work of the new TAH is practically noiseless.
