Koltowski L, Tomaniak M, Ochijewicz D, et al. - Since there exist limited data concerning long-term neointimal healing and neoatherosclerosis progression following primary percutaneous coronary intervention (PCI) with implantation of everolimus-eluting bioresorbable vascular scaffold (BVS) (ABSORB BVS 1.0, Abbott Vascular), thus, researchers undertook this single-center, prospective, longitudinal study to evaluate healing pattern and presence of neoatherosclerosis in 12 ST-segment elevation myocardial infarction (STEMI) patients who underwent serial optical coherence tomography (OCT) evaluation at baseline, 12, 24 and 60 months post-PCI. Participants were observed during a median follow-up of 59 months. Findings revealed that complete scaffold resorption, stable lumen area following period of neointima growth in the first two years post-PCI as well as a high incidence of neoatherosclerosis were indicated by serial OCT imaging performed up to 5 years post-implantation of BVS in STEMI.
