Thirteen patients have been followed from 18 to 30 months after mitral valve replacement by a Starr-Edwards ball valve prosthesis. Ten have been markedly improved and have returned to normal or near normal existence. Two of them, and three who had no improvement died from five to ten months after operation. Late complications include systemic embolization, ventricular arrhythmia and dehiscence of the prosthetic valve permitting regurgitation between left atrium and ventricle.

Failure to improve after operation may be due to regurgitation (sometimes murmurless) or myocardial factor. Despite the late complications seen with this prosthesis, eight of 13 patients have maintained their improvement over the follow-up period.
