    1. Neointima characteristics as a prognostic marker for drug-coated balloon angioplasty in patients with in-stent restenosis: an optical coherence tomography study

      Neointima characteristics as a prognostic marker for drug-coated balloon angioplasty in patients with in-stent restenosis: an optical coherence tomography study

      Background Research has shown that the prognosis of in-stent restenosis (ISR) lesions after drug-coated balloon (DCB) angioplasty can differ in relation to in-stent neointimal characteristics. However, changes in neointima characteristics after DCB have not been studied. This study sought to investigate changes in neointima characteristics after DCB for ISR. Methods From the Yonsei Optical Coherence Tomography (OCT) registry, data on DCBs performed in patients with ISR were collected. Neointima characteristics were categorized as homogeneous, heterogeneous, layered neointima , and neoatherosclerosis in each OCT procedure. Homogeneous and layered neointima were classified as a favorable neointima , while heterogeneous neointima and neoatherosclerosis were classified ...

    2. Comparison of zotarolimus-eluting stent and everolimus-eluting stent for vascular healing response: serial 3-month and 12-month optical coherence tomography study

      Comparison of zotarolimus-eluting stent and everolimus-eluting stent for vascular healing response: serial 3-month and 12-month optical coherence tomography study

      Background: Everolimus-eluting stents (EES) have shown favorable clinical outcomes. However, there have been no studies evaluating early vascular response after EES implantation. We designed a prospective study to compare the neointimal response between zotarolimus-eluting stents (ZES) and EES at 3 and 12 months using serial optical coherence tomography examinations. Methods and results: Sixty patients who underwent 3-month and 12-month follow-up optical coherence tomography (36 EES, 24 ZES) were included. Neointimal coverage and malapposition were evaluated using a strut-based analysis at both 3 and 12 months. Neointimal hyperplasia area and thrombus were assessed. ZES showed a higher incidence of covered struts ...
