Congenital intracardiac band: a rare cause of nonrheumatic combined aortic and mitral regurgitation.

: A patient had a congenital intracardiac band lying across the aortic valve that caused combined aortic and mitral valvular regurgitation. The band was excised, and the damaged aortic valve was replaced with a prosthesis. The case illustrates that not all congenital intracardiac bands are completely asymptomatic and not all bivalvular incompetence is rheumatic in origin.
