      Longitudinal extent of lipid pool assessed by optical coherence tomography predicts microvascular no-reflow after primary percutaneous coronary intervention for ST-segment elevation myocardial infarction

      Background Distal embolization during percutaneous coronary intervention (PCI) may deteriorate microvascular reperfusion in patients with ST-elevation myocardial infarction (STEMI). Reperfusion at the coronary microvascular level is important for STEMI and culprit plaque is associated with distal embolization and microvascular reperfusion. ST-segment resolution (ST-R) in the electrocardiogram reflects microvascular reperfusion after primary PCI. Longitudinal extent of lipid pool assessed by optical coherence tomography (OCT) may predict the risk of failure of microvascular reperfusion after primary PCI. Methods and results This study consisted of 39 patients with STEMI who underwent primary PCI within 24 h after the onset of chest pain. Immediately ...

    2. Correlation Between Plaque Color Classification by Coronary Angioscopy and Fibrous Cap Thickness by Optical Coherence Tomography

      Correlation Between Plaque Color Classification by Coronary Angioscopy and Fibrous Cap Thickness by Optical Coherence Tomography
      Background: Yellow color intensity of coronary plaque evaluated by coronary angioscopy (CAS) might be associated with plaque vulnerability. Pathological studies have reported that vulnerable plaque have the thin cap fibroatheroma (TCFA) with a cap thickness of 65 ┬Ám. Optical coherence tomography (OCT) permit us to evaluate fibrous cap thickness, because OCT has higher resolution than intravascular ultrasound (IVUS), which resolution is approximately 10 to 20 times higher than IVUS. Purpose: This study was undertaken to assess the relationship between plaque color evaluated by CAS and fibrous cap thickness estimated by OCT in patients with acute coronary syndrome (ACS). Methods: 84 ...
