Abstract
Coronary artery aneurysm (CAA) is focal dilatation of a coronary artery 1.5 times or more its normal size (Res Cardiovasc Med, 2016; 5: e32086). Coronary artery aneurysm is found in 1.2-4.9% of diagnostic coronary angiography and 1.4% at post-mortem (Heart Views, 2014; 15: 13; Clin Cardiol, 2015; 29: 439). The proximal and middle segments of the right coronary artery (RCA) are most commonly involved, followed by the proximal left anterior descending (LAD) and the left circumflex arteries. The left main stem rarely develops aneurysms (Clin Cardiol, 2015; 29: 439). A giant aneurysm is a CAA> 2 cm. Giant coronary artery aneurysms (GCAA) are rare (incidence 0.02%) although cause serious complications. [4] Given the rarity of this disease, there is limited information in the literature on its presentation and there is no consensus on its optimal management option. We report a case of a GCAA with an atypical presentation and describe its management. This will add to the current small database on CAA to provide clinicians a better insight on the disease.
