    1. Optical Coherence Tomography Findings of Non-ST Elevation Myocardial Infarction with Multivessel Disease

      Optical Coherence Tomography Findings of Non-ST Elevation Myocardial Infarction with Multivessel Disease

      A 48-year-old man with a history of current smoking presented to our department with sudden-onset chest pain at rest. Elevated high sensitivity troponin level led to urgent coronary angiography (CAG). CAG revealed intermediate stenosis with multiple linear filling defects in the mid right coronary artery (RCA) ( Figure 1A ). Cross-sectional ( Figure 1B-1D ) and longitudinal ( Figure 1F ) optical coherence tomography (OCT) demonstrated a honeycomb-like structure with multiple cavities of various size separated by tissue with high-signal intensity ( Supplementary Video 1 ). Three-dimensional OCT also showed multiple cavities communicating with true lumen ( Figure 1E , asterisks) and we concluded that this represented recanalized thrombus. Regarding ...

    2. Impact of Combination Therapy with Ezetimibe/Simvastatin Treatment on the Neointimal Response to Biodegradable Polymer Biolimus-Eluting Stent Implantation in Patients with Acute Myocardial Infarction: Serial Assessment with Optical Coherence Tomography

      Impact of Combination Therapy with Ezetimibe/Simvastatin Treatment on the Neointimal Response to Biodegradable Polymer Biolimus-Eluting Stent Implantation in Patients with Acute Myocardial Infarction: Serial Assessment with Optical Coherence Tomography

      The aim of this study was to compare the neointimal response at 12-month follow-up between ezetimibe/simvastatin (Vytorin, manufactured by Merck) 10/10 mg and Vytorin 10/40 mg after biodegradable polymer Biolimus-eluting stent (BP-BES) implantation in patients with acute myocardial infarction (AMI). A total of 20 patients requiring revascularization were randomly assigned to receive either Vytorin 10/10 mg (n = 9) or Vytorin 10/40 mg (n = 11). Baseline optical coherence tomography (OCT) was performed after stent implantation, and follow-up OCT was scheduled at 12 months. We performed follow-up OCT in 18 patients (Vytorin 10/10 mg (n = 9 ...

    3. Very late stent thrombosis derived from thin-cap neoatheroma and fibroatheroma with plaque rupture assessed by optical coherence tomography

      Very late stent thrombosis derived from thin-cap neoatheroma and fibroatheroma with plaque rupture assessed by optical coherence tomography

      A 49-year-old woman presented with sudden onset chest pain, at rest, evident of ST-segment elevation in the anterior leads of a 12-lead electrocardiogram. She received stent implantation with a 3.5 × 23 mm sirolimus-eluting stent at the proximal portion of left anterior descending artery (LAD) 10 years ago. Dual antiplatelet therapy, however, was discontinued 3 years ago. Urgent coronary angiography demonstrated a near total occlusion at the proximal portion of LAD, which was the same segment of the previous stent implantation (Fig. 1A). Optical coherence tomography
