Ebstein ’ s Anomaly of Tricuspid Valve

Transcript of the video: Ebstein’s Anomaly is one of the cyanotic congenital heart disease in which survival to adult life is common. In Ebstein’s anomaly, there is downward or apical displacement of posterior and septal tricuspid leaflets. The anterior leaflet is not displaced, but is elongated to meet the other leaflets, so that when it closes, a loud sound, tricuspid sound, is produced, which is called as the sail sound. Ebstein’s anomaly may be associated with atrial septal defect or a patent foramen ovale, in about 50% of cases. The cyanosis in Ebstein’s anomaly, is usually not due to pulmonary hypertension, but because tricuspid regurgitation jet is directed across the atrial septal defect. This is the diagrammatic representation of distal displacement of septal tricuspid leaflet. Anterior leaflet is elongated and sail like. This distance, between the anterior mitral leaflet and septal tricuspid leaflet, is usually only about 5 mm during echocardiography. When it is displaced much, then it is diagnostic of Ebstein’s anomaly. In Ebstein’s, portion of the right ventricle here, is atrialized. This portion is known as atrialized right ventricle. This is the regular right atrium, this is the atrialized portion of right ventricle. This can be a source of cardiac arrhythmia as well. This atrialized portion of right ventricle will have electrocardiographic features of right ventricle and pressure tracing of right atrium. This is known as Hern...
