Abstract

Late-acquired incomplete stent apposition (ISA) is frequently observed after drug-eluting stent (DES) implantation. Most incidences of late-acquired ISA induced by positive vascular remodeling were of the focal type and occurred in a single vessel. We present an unusual case of a 45-year-old male subject diagnosed with late-acquired ISA that occurred in multiple vessels.

Keywords: Drug-eluting stent; Ultrasonography, interventional.
