Large Atherosclerotic Left Main Coronary Aneurysm

Abstract

Coronary artery aneurysm (CAA) is a rare disorder, characterized by an abnormal dilatation of a localized portion of the coronary artery. It is usually diagnosed incidentally by coronary angiography. Over 50% of coronary artery aneurysms are of atherosclerotic origin. The natural history of coronary aneurysms is not well understood. Their presence is not always considered to be an operative indication; rather, the severity of the associated coronary artery disease (CAD) is what dictates a surgical approach. In the absence of obstructive CAD, the definitive treatment for this condition is unclear. The authors present the case of an isolated saccular left main coronary aneurysm with no associated flow-limiting CAD. The patient was treated medically with antiplatelet and anticoagulant medication with no adverse events at 3, 6, 9, and 12 months of follow-up.

“…It is more common in male younger than 40 years old. The incidence of coronary artery aneurysm is 1.5% to 5% [76]. CAD can lead to clinical manifestation such as myocardial infarction, silent ischemia, and stable or unstable angina.…”

Giant Left Main Coronary Artery Aneurysm and Atherosclerotic Coronary Tree: Additive Value of Coronary CT Angiography Over Conventional Angiography

“…In a non-atherosclerotic setting, medial degeneration commonly lies behind the pathophysiologic process. Kawasaki disease and congenital aneurysms lead the list of the causative factors in the absence of atherosclerosis (1,4,5). The left coronary system is less frequently affected than the right coronary artery, and the left main coronary artery (LMCA) is the least of all as the site of involvement (2,5).…”

“…Kawasaki disease and congenital aneurysms lead the list of the causative factors in the absence of atherosclerosis (1,4,5). The left coronary system is less frequently affected than the right coronary artery, and the left main coronary artery (LMCA) is the least of all as the site of involvement (2,5). Diagnosis usually necessitates an additional modality, mostly coronary computed tomography angiography (CCTA), coupled with conventional angiography, and the therapeutic approach remains controversial.…”
