Spontaneous rupture of a giant Coronary Artery Aneurysm after acute Myocardial Infarction

Coronary artery aneurysm is commonly de ined as a localized dilatation exceeding the diameter of adjacent normal coronary segments by 50% [1]. Coronary artery aneurysms may be fusiform, involving the full circumference of the coronary artery, or saccular, involving only a portion of the circumference [2]. Causes of coronary artery aneurysms include atherosclerosis (accounting for 50% of cases), Kawasaki disease, polyarteritis nodosa, infection, trauma, coronary dissection, percutaneous coronary angioplasty, and congenital malformations [3]. The abnormal blood low within the coronary artery aneurysm may lead to thrombus formation, embolization, rupture, myocardial ischemia or myocardial infarction [4]. Here we present a case of a giant fusiform coronary artery aneurysm who passed away due to coronary rupture after acute myocardial infarction.
