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.
