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

Abstract

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.

Uzun Segment Koroner Lezyonlarda Biyoeriyebilen Stentlerin Güvenlik ve Etkinlik Sonlanımları

Abstract

Giriş: Uzun segment lezyonlarda biyoeriyebilen stentlerin (BRS) kullanımı ile ilgili sınırlı bilgimiz olduğundan hem BRS-BRS hem de İlaç salınımlı metal stent (DES)-BRS overlap uygulanan hastaların klinik sonuçlarını değerlendirmeyi planladık.

Hastalar ve Yöntem: Tek merkezli, kesitsel planlanan; Ocak 2013-Haziran 2016 tarihleri arasında uzun segment lezyonlara (> 28 mm) BRS yerleştirilmesi planlanan 97 hasta ve 100 lezyon çalışmaya alındı. Otuz hasta ve 30 lezyonda BRS-BRS overlap uygulanırken , 67 hasta 70 lezyona DES-BRS overlap uygulandı. Akut işlem başarısı ve MACE (ölüm, stent trombozu, hedef damara yeniden girişim) değerlendirildi.

Bulgular: Akut işlem başarısı %97.1 idi. Tüm hasta grubunda toplam MACE 6 (%6.2) hastada gelişirken, DES-BRS grubunda 4 (%5.9), BRS-BRS grubunda 2 (%6.6) hastada MACE gerçekleşti.

Sonuç: Uzun segment lezyonlarda BRS kullanımı seçenek olarak değerlendirilebilinir. BRS-BRS veya BRS-DES overlap yapacak şekilde yerleştiriken kısa segment overlap olacak şekilde gerçekleştirilmelidir.
