Abstract

We herein present a 5-month-old boy with an infravalvular-type left ventricular-right atrial communication without an abnormal tricuspid valve leaflet. The thick chorda of the anterior tricuspid leaflet was inserted into the upper edge of the ventricular septal defect which was placed just under the commissure. The jet from the septal defect pushed this thick chorda and opened the commissure, which thus caused the abnormal pathway from the left ventricle to the right atrium. This mechanism of left ventricular-right atrial communication has not yet been reported elsewhere.
