Left-sided anomalies in Ebstein's malformation of the tricuspid valve.
A review of 34 autopsied cases with classical Ebstein's malformation of the tricuspid valves revealed 8 cases with left-sided anomalies. Among these, appearing in 1 case each, were aortic atresia and persistent common atrioventricular canal. The latter 2 conditions were dominant clinically. In the remaining 6 cases the left-sided anomalies were not apparent clinically and probably of no functional significance. These conditions were parachute mitral valve, bicuspid aortic valve, cor triatriatum and pulmonary stenosis, cleft mitral valve, stenosis of individual pulmonary veins, and prolapse of mitral valve.
