Parachute tricuspid valve in a patient with atrial septal defect detected by two- and three-dimensional echocardiography.

Atrioventricular valve parachute deformity was generally seen in the mitral position, which is called parachute mitral valve. Parachute deformity is also seen in the tricuspid position, but this has rarely been reported as sporadic cases. All of these cases were associated with other congenital defects, such as double outlet right ventricle, left to right shunt. We herein present two- and three-dimensional echocardiographic features of a parachute tricuspid valve in a patient with atrial septal defect and prominent eustachian valve.
