Objectives:
We sought to describe the outcomes of BVS use from a single-center experience in which scaffold implantation was guided by intravascular imaging (ultrasound and/or optical coherence tomography) to identify and treat mechanical factors potentially related to BVS failure.
Background:
The Absorb bioresorbable vascular scaffold (BVS) has been associated with an unexpectedly high incidence of thrombosis.
Methods:
Between 11/2014 and 10/2016, 100 patients were treated with BVS. Intravascular imaging assessment before and after BVS implantation was performed in all cases.
Results:
Mean age was 58.1 years; 88% were male, 31% had diabetes, and 28% presented with acute coronary syndromes. A total of 171 lesions in 141 vessels were treated with 190 BVS (mean 1.9 scaffolds/patient). Further intervention following intravascular imaging to optimize BVS implantation was required in 31% of patients. Procedure success was 100%. All patients completed a 1-year follow-up. The 1-year rate of target lesion failure was 4%, and there were no cases (0%) of scaffold thrombosis, myocardial infarction, or death.
Conclusions:
In this real-world experience, the use of intravascular imaging to guide BVS implantation was associated with a high 1-year event-free survival rate, with no scaffold thrombosis.
