Coronary disease & ACSCohort study
Factors Associated With Chronic Stent Recoil and its Impact on Revascularization
- Observational study
- serial optical coherence tomography (OCT)
Authors' conclusion
Chronic stent recoil after second- or new-generation drug-eluting stent implantation occurred in 1 of 5 lesions undergoing TLR and was associated with TLR.
Study context
- Population
- Patients with second- or newer-generation drug-eluting stents undergoing clinically indicated serial OCT (baseline and at target lesion revascularization (TLR) or after >6-month follow-up)lesions
- Participants
- 163 vs 102
- Exposure
- Lesions undergoing TLR vs lesions not undergoing TLR
- TLRn = 163
- No TLRn = 102reference
- Outcome
- Incidence of chronic stent recoil (>10% stent volume reduction without fracture/deformation or >10% stent area reduction with fracture/deformation) and its impact on TLR
- Follow-up
- Median 16.1 (Q1-Q3: 10.1-29.4) months
Main finding
As reported in the abstract
