    1. Very late stent thrombosis lacking findings of the typical causes on optical coherence tomography in a patient with SARS-CoV-2

      Very late stent thrombosis lacking findings of the typical causes on optical coherence tomography in a patient with SARS-CoV-2

      A 50-year-old male was admitted to our hospital with sudden-onset chest pain. He was a current smoker with severe obesity and diabetes. He had a history of drug-eluting stent (DES) implantation in the left anterior descending artery (LAD) and had continuously taken clopidogrel. Eight days prior to admission, polymerase chain reaction testing confirmed that he was positive for severe acute respiratory syndrome coronavirus type 2 (SARS-CoV-2). Emergent coronary angiography revealed total occlusion of previously implanted DES in LAD. Optical coherence tomography (OCT) images demonstrated the presence of large white thrombus within the well-expanded DES with homogenous neointima. There were no ...

    2. Impact of underlying plaque type on strut coverage in the early phase after drug-eluting stent implantation

      Impact of underlying plaque type on strut coverage in the early phase after drug-eluting stent implantation

      Background The aim of this study was to investigate whether the underlying plaque type affects the neointimal coverage after drug-eluting stent implantation. Methods A total of 1793 struts in 22 zotarolimus-eluting stents were assessed using optical coherence tomography imaging within 3 months of implantation. Neointimal coverage was evaluated within 5 mm from each stent edge on cross-sectional optical coherence tomography images at every 1-mm interval. The percentage of struts covered by neointima was compared among the normal segment group, the fibrous plaque group, and the lipid plaque group on the basis of the underlying plaque type. Results The percentage of ...

    3. Neointimal coverage of zotarolimus-eluting stent at 1, 2, and 3 months' follow-up: an optical coherence tomography study

      Neointimal coverage of zotarolimus-eluting stent at 1, 2, and 3 months' follow-up: an optical coherence tomography study

      Incomplete neointimal coverage and malapposed struts after stenting are associated with increased risk of stent thrombosis. We aimed to evaluate neointimal coverage early after Resolute zotarolimus-eluting stent (R-ZES) implantation using optical coherence tomography (OCT). A total of 20 patients with de novo native coronary lesions with R-ZES were enrolled. Among these patients, 20 stented lesions in 19 patients were evaluated at 1, 2, and 3 months after R-ZES implantation. The strut apposition and neointimal coverage were evaluated by OCT. Neointimal hyperplasia (NIH) thickness and percentage of covered struts and the proportion of incompletely apposed struts were measured at 1-mm intervals ...

      Neoatherosclerosis 16 years following bare-metal stent implantation: Different tissue components in different underlying lesions observed with optical coherence tomography

      A 61 years old male with a history of multiple treatments of percutaneous coronary intervention (PCI) with bare-metal stents (BMS) was admitted for the treatment of acute coronary syndrome (ACS). Sixteen years prior to this admission when he was 45years old, he experienced inferior ST-elevation myocardial infarction. He received one Palmaz-Schatz Stent (PS) for the treatment of lesion in distal right coronary artery (RCA).
