title: [Tricuspid and mitral regurgitation due to congenital hypoplasia of atrioventricular valves in the aged: a case report].
abstract: A 76-year-old woman with a history of repeated right-sided cardiac failure during the past 2 years presented with tricuspid and mitral regurgitation due to congenital hypoplasia of atrioventricular valves. Two-dimensional echocardiography demonstrated enlarged right atrium and right ventricle, and discoaptation between the leaflets. Color Doppler echocardiography revealed severe tricuspid regurgitation through the gap between the leaflets. Autopsy showed congenital hypoplasia of the leaflets and the chordae tendineae in the tricuspid and mitral valvular apparatus.
