A one-piece prosthesis for biventricular cardiac assistance and reanimation is implanted in the right hemithorax between the diaphragm and the right lung symmetrically with respect to a diseased natural heart with which it operates in parallel. The prosthesis comprises a one-piece shell and two blood-circulating deformable-diaphragm pumps actuated by a compressed gas. The prosthesis face which rests on the patient's diaphragm is substantially flat and a substantially orthogonal face is provided with two ports for connecting the prosthesis to the natural heart while the other two connecting ports are inclined at an angle of 45 DEG , connections between the ports and the natural heart being established by means of very short flexible hose elements. A system of port end-fittings serves to connect the prosthesis to the hose elements and to purge the prosthesis or to withdraw any air which may be present.
