Coronary angiogram (Video 1, below) showing a coronary arteriovenous fistula (CAVF) arising from the right marginal artery, draining into coronary sinus, and ultimately draining into a great cardiac vein.

CAVFs are rare congenital anomalies and commonly encountered as an incidental finding on coronary angiography or noninvasive imaging. CAVFs that originate from the middle or proximal right coronary artery to a venous structure may enlarge if left untreated.
