Coronary Artery Ectasia Presenting With Recurrent Inferior Wall Myocardial Infarction

Coronary ectasia presenting as a recurrent inferior myocardial infarction has rarely been reported in the literature. Herein, we report a 61-year-old man who presented with persistent chest pain accompanied by ST segment elevation in the inferior ECG leads. Coronary angiography showed ectasia of the right coronary artery (RCA) and total occlusion from the middle RCA. Two stents were implanted separately in the middle and distal RCA. The patient was readmitted due to recurrent inferior wall infarction 15 months after discharge. He underwent primary percutaneous coronary intervention again, and coronary angiography showed massive thrombosis and in-stent re-stenosis. The thrombosis and re-stenosis were successfully treated using balloon angioplasty. The patient was discharged under medical therapy with aspirin and clopidogrel. There were no anginal symptoms during the 3 years of follow up.
