[Imaging of a congenital coronary fistula using biplane transesophageal color-coded echocardiography. A case report].

A case report of a congenital coronary artery fistula between left main stem and pulmonary artery is presented. This fistula was not detectable by conventional transthoracic color-Doppler echocardiography. In contrast, precise localization of origin and site of drainage of this fistula could be demonstrated by biplane transesophageal color-Doppler echocardiography. Subsequent coronary angiography confirmed the echocardiographic findings.
