Abstract:
We encountered a case of aortic valvuloplasty for aortic regurgitation due to congenital bicuspid valve. A 31-year-old man was found to have aortic regurgitation due to prolapse of a leaflet of the bicuspid valve by echocardiography. Under cardiopulmonary bypass, the right and left coronary cusps were conjoined and that conjoined cusp was larger than that of the opposing leaflet and had a longer free edge. A raphe was present in the conjoined leaflet. At first, we shortened the elongated free edge of the prolapsing leaflet by means of a triangular resection, and placed horizontal mattress sutures at each commissure. Furthermore, we performed subcommissular annuloplasty at each commissure, resulting in good coaptation of cusps. The patient survived and has shown an uneventful recovery. It is likely that this method of aortic valvuloplasty can be used for aortic regurgitation due to congenital bicuspid valve.
