Aim. To establish efficacy and safety of endovascular correction of long coronary lesion with biodegradable scaffolds in comparison with everolimuseluting metallic coronary stents. Materials and methods. From 2013 to 2018 in Republican Scientific and Practical Centre «Cardiology», Minsk, endovascular correction of long (more than 25 mm) coronary artery lesions was performed on 80 patients. Randomly patients were divided into 2 groups: group 1 (n = 40) – endovascular correction with the biodegradable everolimus-eluting vascular scaffold Absorb BVS, and group 2 (n = 40) – endovascular correction with the everolimus-eluting metallic stent Xience V/Xience Pro. Results. In 12-month observational period there were no cases of death or myocardial infarction in both groups. One-year primary endpoint (death + myocardial infarction + target lesion failure) was 10% in group 1 (scaffolds BVS Absorb) and 8.75% in group 2 (Xience stents), 4 and 3 cases of target lesion failure accordingly (p > 0.05). As secondary endpoints there were 3 cases of target lesion revascularization registered and 4 cases of target vessel revascularization in each group, 5 cases of target vessel failure in group 1 and 4 cases in group 2 (p > 0.05). There was 1 case of confirmed and 1 case of probable scaffold thrombosis in group 1 (cumulative rate 5%), no cases of stent thrombosis in group 2 (p = 0.49). Conclusion. Long lesion correction with biodegradable scaffolds shows similar one-year clinical and angiographic results in comparison with everolimuseluting stents. Combined endpoint risk (all death cases + myocardial infarction + revascularization due to target lesion failure) statistically did not differ in one-year period in both groups.
