06-02-36 The left ventricle is viewed posteriorly and is opened in a clam-shell fashion illustrating a cleft in the anterior or aortic leaflet of the mitral valve (yellow arrow). The cleft points to the aortic outflow or aortic valve (yellow dashed arrow) and not to the interatrial septum. In this heart there is a perimembranous ventricular septal defect with a few tendinous cords straddling the interventricular septum and supporting the mitral valve from within the right ventricle.
