Anomalous origin of the right coronary artery from the pulmonary artery in association with congenital aneurysm of the sinus of Valsalva: angiographic diagnosis of a rare association.

A 37 year old man presenting with acute heart failure, hypotension, and acute renal failure was diagnosed by cardiac catheterisation and angiography to have the rare combination of congenital aneurysm of the non-coronary sinus of Valsalva rupturing into the right ventricle, and an anomalous origin of the right coronary artery from the main pulmonary artery. The diagnosis could not be confirmed by transthoracic echocardiography in this patient. This combination of defects, confirmed at cardiac surgery, has not been reported before, and this case report highlights the importance of preoperative definition of congenital defects associated with an aneurysm of the sinus of Valsalva.
