New prosthetic ring for aortic valve annuloplasty.
Aortic valve repair is recently receiving more attention. To broaden the indications for this procedure a prosthetic annuloplasty ring has been developed and tested in animals. Thirty-two sheep underwent implantation of such a ring in the pulmonary (14) and aortic (18) positions. In the 12 survivors followed for a maximum of 200 days the ring was found epithelialized and free from thrombus. One ring was dehiscent; no haemolysis was detected. It is concluded that a small clinical study is warranted.
