Progression of calcification after implantation of a fully bioresorbable scaffold: A serial and combined IVUS-OCT follow-up of 5 years
A 72-year-old female enrolled in the ABSORB Cohort B2 trial underwent successful percutaneous coronary intervention of the proximal left anterior descending artery with a 3 × 18 mm Absorb everolimus-eluting Bioresorbable scaffold (Absorb BVS, Abbott Vascular, CA). Optical coherence tomography (OCT) and intravascular ultrasound (IVUS) images after the procedure showed optimal scaffold expansion without any mechanical complication (Fig. 1: Post-A, C). As protocol mandated, follow-up invasive coronary imagings (angiography, OCT, IVUS) were scheduled at 1-, 3- and 5-year, respectively.
