Transesophageal echocardiographic demonstration of right coronary artery-to-coronary sinus fistula in a heart transplant recipient.
Overview
abstract
A fistula between the distal right coronary artery and coronary sinus was detected by transesophageal echocardiography in a heart transplant recipient. Cineangiograms confirmed this finding to be new since the time of angiography one year earlier. Although coronary artery-to-right ventricular fistulas are not an uncommon complication of endomyocardial biopsy, the echocardiographic findings of a fistula involving the coronary sinus have not been previously described.
