Insights
Giant coronary artery aneurysms (GCAA) are rare but can cause serious complications. This case report details an atypical GCAA presentation and its management, adding valuable data for clinical insight.
Area of Science:
- Cardiology
- Vascular Medicine
Background:
- Coronary artery aneurysm (CAA) is defined as a focal dilatation ≥1.5 times the normal artery size.
- CAAs occur in 1.2-4.9% of diagnostic coronary angiography and 1.4% post-mortem.
- Giant coronary artery aneurysms (GCAA), defined as CAA >2 cm, are rare (0.02% incidence) and associated with serious complications.
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.
