Abstract

Coronary pseudoaneurysm is a rare complication of percutaneous coronary intervention with a drug-eluting stent. Neither precise incidence of the complication has been known, nor there has been any established therapeutic approach for it. A 69-years-old male with effort angina underwent percutaneous coronary intervention to his left main coronary artery (LMCA). After pre-dilatation with a balloon, Endeavor zotarolimus-eluting stent (E-ZES) was successfully implanted into the lesion that extended from his LMCA to left anterior descending artery. At 6 months after stenting, coronary angiography (CAG) and intravascular ultrasound (IVUS) revealed coronary pseudoaneurysm at the stented segment. Follow-up CAG at 13 months after stenting showed the spontaneous and complete resolution of the pseudoaneurysm. Subsequent IVUS, optical coherence tomography, and coronary angioscopy visualized complete neointimal coverage of stent struts. This is the first case report of E-ZES-related pseudoaneurysm with relatively rapid resolution. Our patient suggests that E-ZES might incidentally contribute to this favorable outcome.
