Key result
Aortic valve replacement can rarely be complicated by a postoperative left ventricular-right atrial communication, diagnosable via transesophageal echocardiography.
Transesophageal echocardiography is useful for diagnosing rare intracardiac defects like LV-RA communication after aortic valve surgery.

May prompt TEE evaluation for LV-RA shunt after AVR; leaves open true incidence and management.
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.
