An unusual form of coronary artery fistula: a small aneurysm of vieussens' arterial ring communicating with the pulmonary artery.
Vieussens' arterial ring (VAR) is the connection between the conus branch of the right coronary artery and the proximal right ventricular branch of the left anterior descending coronary artery. VARs are found in 48% of the population; however, pathologic VAR is rare. We experienced a case of pathologic VAR that involved a fistula connecting to the main pulmonary artery.
