Coronary aneurysm complicated by acute myocardial infarction

The case of a 55 years old, hypertensive, obese female is presented, who came to the emergency department with inferoposterior ST segment elevation myocardial infarction (STEMI) with right ventricular infarction. After thrombolytic therapy, she reperfused but had anginal symptoms on minimal activity. The patient underwent coronary angiogram which showed aneurysmal right coronary artery (RCA) with 60% stenosis and thrombus in mid portion and distal bifurcation of RCA with TIMI III distal blood flow. Left main coronary artery was normal. Left anterior descending (LAD) and Left circumflex (LCX) arteries were also aneurysmal and non obstructive. The patient was started on intravenous heparin and warfarin in view of aneurysmal coronary arteries and large thrombus burden. The patient was discharged home in one week and is doing well at follow up.
