A rare case of diffuse ectasia in the coronary arteries and proximal aneurysm in the left anterior descending artery: A case report

INTRODUCTION: Coronary artery aneurysm is defined as dilatation of a segment of coronary artery, greater than 1.5 times the diameter of the largest normal coronary artery of the patient. Major cause of coronary artery aneurysm is coronary artery disease. Coronary artery aneurysm maybe an incidental finding during coronary angiography or it may present with symptoms including chest pain, myocardial infarction or even death. CASE PRESENTATION: We present a rare case of a 59-year-old gentleman, who had, previously, underwent multiple left heart catheterizations and percutaneous coronary interventions. He presented to us with symptomatic diffuse ectasia of the coronary arteries with proximal aneurysm in the Left Anterior Descending Artery. DISCUSSION: Coronary artery aneurysms are very rare with an incidence of about 0.02 %–0.04 % and a prevalence of 0.3 %–12 %. Right Coronary Artery is the principal site coronary artery aneurysms with a predominance of 83.8 %. The occurrence of multiple aneurysms is a very rare finding. About 73 % patients present with single aneurysms while only 27 % present with multiple aneurysms. Coronary artery aneurysms predispose to various complications including compression of the chambers, thrombosis and rupture. CONCLUSION: From the presented case it can be concluded that even though, conservative management is available, surgical repair is the gold standard treatment, especially in the presence of multiple, symptomatic and large aneurysms in order to avoid fatal ischemic complications.
