Description

Congenital anomalies of the coronary arteries are uncommon and can present a diagnostic challenge. The authors present the case of a patient with recurrent chest pain during exertion admitted for acute coronary syndrome. Coronary angiography revealed no coronary lesions but showed that the right coronary artery originated from the anterolateral aortic wall, above the sinuses of Valsalva, leading to suspicion of compression by the pulmonary artery, confirmed by CT angiography. The patient underwent surgical revascularization with a good result. The authors highlight the need to consider compression of an anomalous coronary artery by the pulmonary artery in the differential diagnosis of recurrent chest pain on exertion and acute myocardial infarction without significant coronary stenosis.
