[Decision-making while implantation of biodegradable vascular scaffolds ABSORB based on methods of intravascular visualization].

A series of studies demonstrated comparability of the incidence rate of major adverse cardiac events (MACE) in the middle-term postoperative period following implantation of last-generation drug-coated stents and biodegradable intravascular scaffolds. It was noted observed that these complications may be associated with malposition and inadequate inappropriate preparation of the lesion. We carried out a total of 16 percutaneous coronary interventions (PCI) with implantation of absorbable vascular scaffolds (Absorb, Abbott Vascular) under the guidance of optical coherent tomography. Besides, a further 16 PCIs were performed without intravascular visualization (control group). As experience was gathered, the algorithm of carrying out optical coherent tomography was subjected to changes, resulting in proposal of an optimal algorithm for choice of intraoperative policy based on the findings obtained in optical coherent tomography.
