Introduction
Anomalous aortic origin of the right coronary artery (AAORCA) from the left sinus of Valsalva is an uncommon condition that reportedly causes sudden cardiac death. It involves the compression of the coronary arteries due to dilatation of the aorta or pulmonary artery trunk. The enlargement of the sinus of Valsalva in acute aortic dissection (AAD) possibly led to acute myocardial infarction (AMI) by a similar mechanism, discussed below.
