Gerbode ventricular septal defect

What it means

A type of ventricular septal defect communicating directly between the left ventricle and right atrium. This is anatomically possible because the normal tricuspid valve is more apically displaced than the mitral valve.

Echocardiography may visualize a jet across a small defect between left ventricle and right atrium.
