Uncommon pattern of tricuspid stenosis in Ebstein's anomaly.
The echocardiographic and cineangiographic features of an unusual type of tricuspid stenosis in Ebstein's anomaly are described. The displaced septal and mural leaflets of the tricuspid valve are inserted to an anomalous apical muscle shelf and cause a restrictive communication between the atrialized portion and the trabecular zone of the right ventricle. The antero-superior leaflet is not involved.
