Abstract
Coronary artery ectasia (CAE) is a rare condition, affecting 3%-8% of patients with atherosclerotic coronary artery disease, and is characterized by the abnormal dilatation of the coronary arteries. While the etiology of coronary artery ectasia encompasses a myriad of acquired and geneticfactors, its pathogenesis still remains a subject of investigation. The clinical manifestations are varied, ranging from asymptomatic cases to chest angina and myocardial infarction. Coronary angiography remains the gold standard for diagnosing CAE. We herein report four cases of coronary ectasia: the first involving myocardial infarction, the second associated with bicuspid aortic valve with severe aortic regurgitation, the third detected during coronary angiography for moderate left ventricular dysfunction,and the last one detected during coronary angiography for stable angina. The aims of our study are to highlight the diversity of clinical presentations as well as the challenge of management, given that there are no universal treatments or guidelines.
