Spontaneous thrombosis in a coronary artery fistula with aneurysmal dilatation of the sinus of Valsalva.

This case report describes spontaneous thrombosis of a congenital coronary artery fistula with associated aneurysmal dilatation of the right coronary sinus of Valsalva. The grossly dilated sinus of Valsalva was reconstructed with a Dacron patch. Coronary revascularization was performed with a sequential saphenous vein graft anastomosed to the right posterior descending and posterior ventricular arteries distally and to the aorta proximally.
