Long-term clinical outcomes of late stent malapposition detected by optical coherence tomography after drug-eluting stent implantation
Journal of the American Heart Association Mar 29, 2019
Im E, et al. - Researchers examined 351 patients who received drug-eluting stents to determine long-term clinical outcomes of late stent malapposition (LSM) detected by optical coherence tomography (OCT). In 99 patients (28%), LSM was detected. They focused on the cumulative rate of composite events (cardiovascular death, target-vessel–related myocardial infarction, target-vessel revascularization, and stent thrombosis). Participants were followed long-term (>5 years), during which, no occurrence of very late stent thrombosis was found in patients with OCT-detected LSM. Patients with LSM vs those without LSM were found to have comparable rates of adverse clinical events. No link was found between the presence of OCT-detected LSM and unfavorable clinical results.
