Exclusion of a Giant Coronary Artery Aneurysm With Covered Stents Using a Long Drug-Eluting Stent Scaffold

Abstract

Coronary artery aneurysms (CAA) are a rare cause of acute coronary syndrome and there is little consensus as to the optimal treatment. Based on case series as well as expert opinion, surgery has been suggested as the optimal treatment for a giant CAA. Here, we present the case of a patient with recurrent myocardial infarction and severe angina due to a giant CAA, who was deemed a poor surgical candidate due to his multiple medical comorbidities. Given his intractable anginal symptoms despite medical therapy, he chose to pursue percutaneous intervention. However, the aneurysm was larger than available covered coronary stents and the patient had significant atherosclerotic disease proximal and distal to the aneurysm itself. Our approach used a long drug-eluting stent as a scaffold to overlap covered coronary stents to successfully exclude the aneurysm. The patient’s angina resolved and had no complications or readmissions after nearly 1 year of follow-up.
