    1. Does spotty calcification attenuate the response of nonculprit plaque to statin therapy?: A serial optical coherence tomography study

      Does spotty calcification attenuate the response of nonculprit plaque to statin therapy?: A serial optical coherence tomography study
      Objectives The aim of this study was to determine if spotty calcification decreases the response of plaque progression to statin therapy. Background Previous studies showed that the presence of spotty calcification is a marker of vulnerable plaque. However, the relationship between spotty calcification and plaque progression is not clear. Methods Ninety-six nonculprit lipid-rich plaques in 69 patients who received serial optical coherence tomography (OCT) imaging were included. Plaques were divided ...

    2. EROSION Study (Effective Anti-Thrombotic Therapy Without Stenting: Intravascular Optical Coherence Tomography–Based Management in Plaque Erosion)

      EROSION Study (Effective Anti-Thrombotic Therapy Without Stenting: Intravascular Optical Coherence Tomography–Based Management in Plaque Erosion)
      Background The initial EROSION study (Effective Anti-Thrombotic Therapy Without Stenting: Intravascular Optical Coherence TomographyBased Management in Plaque Erosion) demonstrated that patients with acute coronary syndrome caused by plaque erosion might be stabilized with aspirin and ticagrelor without stenting for 1 month. However, a long-term evaluation of outcomes is lacking. The aim of this study was to assess whether the initial benefit of noninterventional therapy for patients with acute coronary syndrome ...

    3. Chronic kidney disease predicts coronary plaque vulnerability: an optical coherence tomography study

      Chronic kidney disease predicts coronary plaque vulnerability: an optical coherence tomography study
      Objective: The addition of cystatin C to creatinine in calculating the estimated glomerular filtration rate (eGFR) is known to improve the risk prediction for cardiovascular events. We sought to investigate the associations between eGFRs calculated by three Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations and coronary plaque phenotype by optical coherence tomography. Patients and methods: We analyzed 181 nonculprit plaques from 116 coronary artery disease patients. For each patient, the ...

    5. Impact of Age on Stent Strut Coverage and Neointimal Remodeling as Assessed by Optical Coherence Tomography

      Impact of Age on Stent Strut Coverage and Neointimal Remodeling as Assessed by Optical Coherence Tomography
      Abstract: While older age associates with adverse percutaneous coronary intervention (PCI) outcomes, detailed information relating age to stent strut coverage and neointimal characteristics is lacking. One hundred nineteen patients with 123 sirolimus-eluting stents (SESs) were divided into 3 groups: group A (55 years), group B (5665 years), and group C (65 years). At 6 and 12 months of follow-up, optical coherence tomography was performed to assess strut coverage and neointimal ...

    6. 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 ...

    7. 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 ...

      Aims To study in-stent tissue characteristics by optical coherence tomography (OCT) at long-term follow-up in patients with previous bare metal stent implantation. Methods and results Among 1636 patients who underwent bare metal stent (BMS) implantation between 1999 and 2006, 39 patients with 60 BMS who developed recurrent ischaemia underwent repeat catheterisation and OCT imaging between June 2008 and August 2009.

    17. In Vivo Optical Coherence Tomography (OCT) of Experimental Thrombosis in a Rabbit Carotid Model

      Background Plaque rupture with subsequent thrombosis is recognized as the underlying pathophysiology of most acute coronary syndromes. Thus, direct thrombus visualization in vivo may be beneficial for both diagnosis and guidance of therapy. We sought to test the feasibility of imaging acute thrombosis in vivo using OCT, in an experimental thrombosis animal model. Methods and Results Nine male New Zealand White rabbits (weight, ¡Ö3.0 kg) were made atherosclerotic with ...
