Abstract
Implantation of drug-eluting stent can result a rare complication of coronary artery aneurysm. We report a case of giant coronary artery aneurysm presented with acute myocardial infarction, which was successfully treated by sequential implantation of two covered stents. At 2-month follow-up, the patient presented with mass effect of the thrombosis aneurysm compressing the right ventricle, improved with conservative management.
Highlights
Introduction of Drug-Eluting Stent (DES) proved to be an important step forward in reducing rates of restenosis and target lesion revascularization after percutaneous coronary intervention, but at the same time potentially causing serious complications
We report a case of giant Coronary Artery Aneurysm (CAA) after DES implantation presenting with acute myocardial infarction and cardiogenic shock, which was treated by percutaneous coronary intervention using two sequential covered stents
Coronary artery aneurysms after percutaneous coronary intervention are rare, with a reported incidence of 0.3% to 6.0%; and giant CAAs are very rare with a reported incidence of 0.02% [6]
Summary
Introduction of Drug-Eluting Stent (DES) proved to be an important step forward in reducing rates of restenosis and target lesion revascularization after percutaneous coronary intervention, but at the same time potentially causing serious complications. One of the rare complications of DES is coronary artery aneurysm. Coronary Artery Aneurysm (CAA), defined as localized dilatation of the coronary artery exceeding 50% of the reference vessel diameter is considered as very rare, with a reported incidence of 0.3-6% after percutaneous coronary intervention [1].
