Congenital Diverticulum of the Right and Left Ventricles

Abstract

An asymptomatic congenital cardiac diverticulum was seen on a routine chest film in a 45-year-old man. Right atrial and left ventricular cineangiography showed that the diverticulum communicated independently with both ventricles. There was no evidence of heart failure, arrhythmia, or mural thrombus, and surgery was not deemed necessary.
