    The fate of incomplete stent apposition with drug-eluting stents: an optical coherence tomography-based natural history study

    Aims To assess the fate of incomplete stent apposition (ISA) after deployment of sirolimus-eluting stents (SESs). Methods and results Thirty-two patients having intravascular ultrasound (IVUS)-guided PCI with SESs underwent assessment of stent deployment with quantitative coronary angiography, IVUS, and optical coherence tomography (OCT) pre-procedure, post-procedure, and at 10 months follow-up. Incomplete stent apposition was defined as separation of a stent strut from the inner vessel wall by >160 µm. At follow-up, 4.67% of struts with ISA at deployment failed to heal and 7.59% which were well apposed did not develop neointimal hyperplasia even after 10 months. Lesion ...
