Abstract
|
|
Introduction:
Coronary artery ectasia (CAE) is a very rare condition with unclear etiology, clinical significance, and proper management strategies.
Case Report: A 54-year-old male who had an ST-elevation myocardial infarction (STEMI) as an initial presentation of a significantly ectatic left circumflex coronary artery (LCX) with a diameter of 8mm. The patient presented to the hospital with chest pain. Upon further evaluations, he was deemed to be having an STEMI noted in the lateral EKG leads in addition to elevated troponin I level. The patient underwent left heart catheterization which revealed an ectatic LCX with a diameter close to 8 mm, with an acute thrombus and occlusion of the distal LCX and severe atherosclerosis. Percutaneous coronary intervention was done to re-establish flow to the obtuse marginal artery (OM). Subsequently, patient underwent coronary artery bypass grafting two days later. He was discharged home three days after surgery in stable condition on aspirin and clopidogrel. Conclusion: This case is unique as it describes a significantly aneurysmal LCX which is very wide in diameter complicated with an intraluminal thrombus without a prior warning in this patient, all managed successfully. Literature provides limited information regarding optimal management of similar conditions. | |
