Abstract
We discuss the usefulness of the Cosgrove-Edwards ring from our early clinical results from 25 rings in 24 patients who underwent mitral annuloplasty (MAP) or tricuspid annuloplasty (TAP) between June 1999 and December 2000. In the MAP group, the posterior mitral annulus between the anterior and posterior fibrous trigones was reinforced with the prosthetic ring. In the TAP group, the annuli of the anterior and posterior leaflets were splinted with the ring. The prosthetic ring was attached by pledgeted U-sutures. Cardiologists performed echocardiography pre- and postoperatively. Thirteen of the 14 in the MAP group showed mitral valve regurgitation of grade 0 or I. Six of the 11 in the TAP group showed tricuspid regurgitation of grade 0 or I, and 5 patients with regurgitation equal to or greater than grade II who remained in atrial fibrillation postoperatively recovered without further clinical symptoms. No patient has required reoperation during a follow-up period of up to 2 years. Cosgrove-Edwards ring-related complications, such as valve stenosis, ring detachment, and arrhythmia, have been not recognized in these patients. In conclusion, for mitral and tricuspid annuloplasty, the Cosgrove-Edwards prosthetic ring showed excellent early clinical results, particularly in patients maintained in sinus rhythm.
