Safety and Efficacy Outcomes of Bioresorbable Scaffolds in Long Segment Coronary Lesions

Introduction: There is limited knowledge about the use of bioresorbable scaffolds (BRSs) in long segment coronary artery lesions. We aimed to evaluate the clinical outcomes of BRS-BRS and drug eluting stents (DESs)-BRS overlapping applications. Patients and Methods: Cross-sectional, single-center study between 2013 and 2016 enrolled 97 patients and 100 lesions scheduled for BRS placement in long segment lesions (> 28 mm). BRS-BRS overlap was performed in 30 patients and 30 lesions, DES-BRS overlap was performed in 67 patients and 70 lesions. Acute procedural success and major adverse cardiac events (MACE) (death, stent thrombosis, and target lesion reintervention) were assessed. Results: Acute procedural success was 97.1% in the overall group. MACE was observed in 6 patients (6.2%) in the entire group, 4 (5.9%) in the DES-BRS group, and 2 (6.6%) in the BRS-BRS group. Conclusion: BRS use might be a safe and effective option for the treatment of long segment lesions. Both BRS-BRS overlap and BRS-DES overlap may be performed with short overlap segment
