A Fractured Sirolimus-Eluting Stent With a Coronary Aneurysm

A 55-year-old man had undergone successful percutaneous intervention with a sirolimus-eluting stent, placed in the right coronary artery (2.5 × 33 mm) and distal left circumflex artery (3.0 × 28 mm) without high pressure ballooning. Twelve months later he presented with unstable angina. Angiography revealed two fracture sites on the right coronary artery–deployed stent, with a large aneurysm and an aneurysmal dilatation of the left circumflex artery without stent fracture. Due to the potential risk of aneurysmal rupture, he underwent coronary artery bypass grafting and ligation of the aneurysm.
