Specimen walkthrough 14- Ebstein malformation! Cardiac anatomy & pathology!

Specimen with Ebstein malformation. The inferior leaflet of the tricuspid valve is quite large and isn't well delaminated from the underlying myocardium (not completely excavated from the underlying myocardium). The septal leaflet of the tricuspid is also not well delaminated and has rolled, thickened edges. The anterior leaflet of the tricuspid valve is large, and sail-like. The tricuspid valve is not inferiorly displaced as this is not a proper description of any tricuspid valve with Ebstein malformation. When in attitudinally appropriate position an inferior displacement of the tricuspid valve would require the tricuspid valve to leave the heart. Instead the tricuspid valve is best described as being abnormally rotated. The leaflets coapt in an abnormal position, further away from the right atrioventricular groove. Generally the tricuspid valve is at the level of the right atrioventricular groove. Thus, the distance between the right atrioventricular groove and the tricuspid valve leaflet edges represents "atrialized" right ventricle. There is an oval fossa atrial septal defect as well.
