| IPCCC Definition | A congenital cardiac malformation in which there is a ventricular septal defect that opens to the right ventricle in the postero-inferior region of the trabeculated component of the ventricular septum. |
-
The anterior free wall of the right atrium and right ventricle have been removed to demonstrate a muscular ventricular septal defect along the postero-inferior aspect of the trabecular component of the ventricular septum. This ventricular septal defect is well away from the septal leaflet of the tricuspid valve and lies near the diaphragmatic aspect of the right ventricle. There are tendinous cords passing anterior to the defect and attaching to the inferior papillary muscle. Note the atrial septal defect and perimembranous ventricular septal defects that were previously repaired. - Content for Echocardiogram

Image #1: In this anterior view, the right ventricle is opened in clam-shell fashion to demonstrate a large, fistulous communication between the coronary arteries and the right ventricle (black arrows). The inferior interventricular coronary arteries both contribute to this fistulous communication.

The apical trabecular component and the outlet have been mostly obliterated by muscular hypertrophy.
