Coronary Artery Aneurysm After Everolimus-Eluting Bioabsorbable Vascular Scaffold Implantation.

A mong the rare complications after percutaneous coronary intervention, coronary artery aneurysms (CAA) reportedly have an incidence of 0.3% to 6.0%. The detection of CAAs vary from 3 days to up to 4 years after drug-eluting stent (DES) and from 6 days to up to 6 years after baremetal stents (BMS) implantation. Associated factors include residual dissection and deep arterial wall injury caused by oversized balloons or stents, highpressure balloon inflations, atherectomy, and laser angioplasty (1,2). Though the pathogenesis of CAA after DES, as well as after BMS, implantation has been studied, there seems to be neither sufficient literature nor adequate evidence of CAA after a
