    2. Insights into the spatial distribution of lipid-rich plaques in relation to coronary artery bifurcations: an in-vivo optical coherence tomography study

      Insights into the spatial distribution of lipid-rich plaques in relation to coronary artery bifurcations: an in-vivo optical coherence tomography study
      Objectives: The aim of this study was to investigate the spatial location of vulnerable plaques at coronary artery bifurcations using frequency domain-optical coherence tomography. Background: In-vivo data on geometric location of vulnerable plaques in relation to coronary bifurcation are limited. Materials and methods: A total of 40 patients with left anterior descending artery bifurcation were studied. Plaque characteristics in five regions in relation to a side branch were compared: opposite ...

    4. Pancoronary Plaque Vulnerability in Patients with Acute Coronary Syndrome and Ruptured Culprit Plaque: A Three-Vessel Optical Coherence Tomography Study

      Pancoronary Plaque Vulnerability in Patients with Acute Coronary Syndrome and Ruptured Culprit Plaque: A Three-Vessel Optical Coherence Tomography Study
      Background Recent studies described different clinical and underlying plaque characteristics between patients with and without plaque rupture presenting with acute coronary syndrome (ACS). In light of the systemic nature of atherosclerosis, we hypothesized that non-culprit plaques might also express different morphological features in these two groups of patients. Methods Thirty-eight patients with ACS who underwent 3-vessel optical coherence tomography (OCT) imaging were identified from the Massachusetts General Hospital OCT Registry ...

    5. Feature Of The Week 8/4/13: MGH OCT Registry Reports on In Vivo OCT Studies of Plaque Erosion and Calcified Nodule In Acute Coronary Syndrome

      Feature Of The Week 8/4/13: MGH OCT Registry Reports on In Vivo OCT Studies of Plaque Erosion and Calcified Nodule In Acute Coronary Syndrome
      Pathology studies reported that three most common causes of acute coronary syndrome (ACS) or sudden cardiac death are plaque rupture, plaque erosion and calcified nodules. The morphological and clinical characteristics of the underlying pathology of ACS, especially plaque erosion and calcified nodule, have never been well studied in vivo. Using optical coherence tomography, we found that plaque erosions are the substrate for ACS in 31% of patients and calcified nodules ...

    7. In Vivo Diagnosis of Plaque Erosion and Calcified Nodule in Patients with Acute Coronary Syndrome by Intravascular Optical Coherence Tomography

      In Vivo Diagnosis of Plaque Erosion and Calcified Nodule in Patients with Acute Coronary Syndrome by Intravascular Optical Coherence Tomography
      Objectives To characterize the morphological features of plaque erosion and calcified nodule in patients with acute coronary syndrome (ACS) by optical coherence tomography (OCT). Background Plaque erosion and calcified nodule have not been systematically investigated in vivo . Methods One hundred and twenty-six patients with ACS who had undergone pre-intervention OCT imaging were included. The culprit lesions were classified as plaque rupture (PR), erosion (OCT-erosion), calcified nodule (OCT-CN), or others using ...

    8. Angiographically silent very late stent thrombosis detected by optical coherence tomography in association with peri-stent staining and multiple interstrut cavities

      Angiographically silent very late stent thrombosis detected by optical coherence tomography in association with peri-stent staining and multiple interstrut cavities
      A 56-year-old-man had unstable angina 7 years previously, which was treated with two sirolimus-eluting stents (SESs) in the proximal and mid-left anterior descending artery (LAD) and one SES in a diagonal branch. Five years later, he developed stent thrombosis in the mid-LAD SES that required treatment with two additional everolimus-eluting stents ( Panel A , lines outline stents). Intravascular ultrasound confirmed that all
