Aim

The aim of this long-term registry data was to evaluate 2-year clinical and angiographic outcomes after implantation of everolimus-eluting bioresorbable scaffolds (Absorb) from the Latvian Centre of Cardiology Real-life Registry.

Material and methods

Between November 2012 and December 2014 in the Centre of Cardiology Real-life Bioresorbable Vascular Scaffold Registry, 187 patients with stable angina or acute coronary syndrome and available 2-year follow-up were selected. All patients had percutaneous coronary intervention (PCI) following bioresorbable scaffold (Absorb) implantation. At 2 years, clinical parameters were analysed in stable angina and acute coronary syndrome subgroups: all-cause death, cardiac death, non-cardiac death, myocardial infarction (MI), target lesion revascularization (TLR), target vessel revascularization (TVR), scaffold thrombosis (ST), cerebral infarction, in-scaffold restenosis and bleeding.

Results

The clinical follow-up rate at 2 years was 96.2%. In-hospital death occurred in 2 (1.1%) patients, and 1 (0.5%) patient had in-hospital MI. At 2 years, the rate of all-cause death was 3.9% (n = 7), MI 1.6% (n = 3), TLR 3.9% (n = 7), and TVR 8.4% (n = 15). Between hospital discharge and 2-year follow-up scaffold thrombosis occurred in 2 (1.1%) patients. In-hospital scaffold thrombosis occurred in 1 (0.5%) patient due to clopidogrel resistance, and 1 additional case of scaffold thrombosis occurred at 5 days after implantation (0.5%).

Conclusions

Bioresorbable scaffolds showed acceptable efficacy (target lesion revascularization) and safety (cardiac death, myocardial infarction, and scaffold thrombosis) results at mid-term follow-up in stable angina and acute coronary syndrome patients.
