Acquired left ventricular to right atrial communication and complete heart block following nonpenetrating cardiac trauma.

Intracardiac shunts are uncommon cardiac lesions caused by blunt chest trauma. A very unusual case is reported of a young male with an acquired left ventricular to right atrial communication and complete heart block cause by nonpenetrating chest trauma. The left ventricular to right atrial fistula was diagnosed noninvasively by transthoracic and transesophageal echo-Doppler examination and the findings were confirmed by left ventriculography and by the intraoperative findings.
