Mitral Insufficiency and Aortic Valve Stenosis in Infancy Associated with Endocardial Fibroelastosis, Surgical Treatment and Long-term Results

Abstract

Surgical treatment of mitral insufficiency and aortic valve stenosis associated with endocardial fibroelastosis has not been well documented. We treated 2 infants with this complex lesion: in one case it was possible to repair the mitral valve. The long-term results are quite encouraging and emphasize that this lesion should be treated early to avoid the risk of compromising the left ventricular function, although the chance of a valve replacement in an infant can be high.
