    1. Intravascular modality‐guided versus angiography‐guided percutaneous coronary intervention in acute myocardial infarction

      Intravascular modality‐guided versus angiography‐guided percutaneous coronary intervention in acute myocardial infarction

      Background Few data are available for current usage patterns of intravascular modalities such as intravascular ultrasound (IVUS), optical coherence tomography (OCT), and fractional flow reserve (FFR) in acute myocardial infarction (AMI). Moreover, patient and procedural‐based outcomes related to intravascular modality guidance compared to angiography guidance have not been fully investigated yet. Methods We examined 11,731 patients who underwent percutaneous coronary intervention (PCI) from the Korea AMI Registry–National Institute of Health database. Patient‐oriented composite endpoint (POCE) was defined as all‐cause death, any infarction, and any revascularization. Device‐oriented composite endpoint (DOCE) was defined as cardiac death ...

    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. The role of optical coherence tomography in the setting of acute myocardial infarction

      The role of optical coherence tomography in the setting of acute myocardial infarction

      In recent years, intravascular imaging-guided percutaneous coronary intervention (PCI) has been increasing in patients with acute myocardial infarction (AMI). However, the role of optical coherence tomography (OCT) has not been established in the setting of AMI despite OCT providing superior resolution (10 μm axial resolution) and facilitating assessment of baseline lesion characteristics and post-intervention evaluation of the acute result of stent implantation, including visualization of procedural dissections, malapposition, tissue prolapse, and thrombus. We provide an overview of the potential benefits of OCT-guidance in various situations of AMI

    4. 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
