Very late scaffold thrombosis: insights from optical coherence tomography and histopathology

A 79-year-old male patient had a 2.5×12 mm bioresorbable vascular scaffold (Absorb™ BVS; Abbott Vascular, Santa Clara, CA, USA) implanted in the setting of the RIBS VI study protocol for in-stent restenosis of a 3×9 mm bare metal stent (AVE S670; Medtronic, Minneapolis, MN, USA) in January 2015, at which time point the patient presented with stable angina and positive exercise stress test (index procedure). The Absorb BVS was implanted with predilatation at 20 atmospheres (atm) accompanied by post-dilatation with a non-compliant balloon (2.5×10 mm) at 26 atm. The patient was maintained on dual antiplatelet ...
