Unusual complication after aortic valve replacement.

We present a report of a postoperative left ventricular-right atrial (LV-RA) communication after aortic valve replacement. Such intracardiac defects are rare but encountered occasionally after valve surgery. The diagnosis was made by use of transesophageal echocardiography with echo-Doppler and color-flow imaging. Complications of LV-RA shunts and differential diagnosis are discussed.
