ABSTRACT:
A sigmoid heart valve annuloplasty prosthetic ring is disclosed which has a biocompatible stent molded into a scalloped shape, having three sinusoidal struts, to adapt to the anatomical shape of the annulus of the human sigmoid valves. The prosthetic ring is covered with biocompatible cloth. The prosthetic ring can be incorporated into the extremity of a biocompatible tubular cloth which serves as a vascular prosthesis in order to permit the total replacement of the ascending aorta or pulmonary artery without replacing the sigmoid valve.
