Treatment of a giant coronary artery aneurysm: intravascular ultrasound and optical coherence tomography findings.

A giant coronary aneurysm (GCA) partially thrombosed was demonstrated in a 77-year-old patient evaluated for an inferior myocardial infarction. Primary angioplasty (balloon only) with suboptimal result was initially obtained. After triple antiplatelet and anticoagulation therapy (4 days), a new angiography was performed and a fusiform GCA was clearly delineated. A second percutaneous intervention was performed using a "scaffolding technique" with conventional stent and subsequent implantation of 2 polytetrafluoroethylene-covered stents to successfully exclude the aneurysm. This case demonstrates a novel technique to treat long GCA.
