Bioresorbable Vascular Scaffolds in coronary chronic total occlusions. Clinical, vasomotor and optical coherence tomography findings at 3-year follow-up (ABSORB-CTO study)
Aims: Percutaneous treatment of coronary chronic total occlusion (CTO) is associated with important arterial remodelling after successful recanalization. Bioresorbable vascular scaffold (BVS) implantation in CTO has been shown feasible and can be of interest when the scaffold achieves complete bioresorption. We sought to evaluate the 3-year results in terms of clinical events, serial imaging outcomes and the vasomotion response in CTO lesions successfully treated with BVS. Methods and results: A total of 33 patients (35 CTO lesions) successfully treated with BVS were included in ABSORB-CTO study. Clinical outcomes, quantitative coronary angiography (QCA) and optical coherence tomography (OCT) assessment were analysed ...
