    2. Segmentation and quantification of blood vessels for OCT-based micro-angiograms using hybrid shape/intensity compounding

      Segmentation and quantification of blood vessels for OCT-based micro-angiograms using hybrid shape/intensity compounding
      Optical coherence tomography (OCT) based microangiography is capable of visualizing 3D functional blood vessel networks within microcirculatory tissue beds in vivo. To provide the quantitative information of vasculature from the microangiograms such as vessel diameter and morphology, it is necessary to develop efficient vessel segmentation algorithms. In this paper, we propose to develop a hybrid Hessian/intensity based method to segment and quantify shape and diameter of the blood vessels ...

    3. Nonangiographic assessment of coronary artery disease: a practical approach to optical coherence tomography and fractional flow reserve

      Nonangiographic assessment of coronary artery disease: a practical approach to optical coherence tomography and fractional flow reserve
      In an era of increased scrutiny of the appropriateness and safety of revascularization, interventional cardiologists must evolve by adding key tools to their armamentarium. This review highlights the utility of optical coherence tomography and fractional flow reserve in the catheterization lab and provides a practical guide for using these technologies during coronary intervention in various lesion subsets. We propose that fractional flow reserve informs the decision to intervene and optical ...

    4. Prevalence and Characteristics of TCFA and Degree of Coronary Artery Stenosis An OCT, IVUS, and Angiographic Study

      Prevalence and Characteristics of TCFA and Degree of Coronary Artery Stenosis An OCT, IVUS, and Angiographic Study
      Background The relationship between features of vulnerable plaque and angiographic coronary stenosis is unknown. Objectives The purpose of this study was to systematically investigate the absolute number, relative prevalence, and characteristics of thin-cap fibroatheroma (TCFA) at different degrees of stenosis using optical coherence tomography (OCT), intravascular ultrasound, and coronary angiography. Methods We identified 643 plaques from 255 subjects who underwent OCT imaging in all 3 coronary arteries. They were divided ...

    5. Morphologic Characteristics of Eroded Coronary Plaques: A Combined Angiographic, Optical Coherence Tomography, and Intravascular Ultrasound Study

      Morphologic Characteristics of Eroded Coronary Plaques: A Combined Angiographic, Optical Coherence Tomography, and Intravascular Ultrasound Study
      Plaque erosion accounts for about one-third of acute coronary syndrome (ACS) [1]. Systemic milieu such as high inflammatory and/or thrombogenic status may be an essential precondition for the occurrence of plaque erosion [2]. However, ACS patients frequently have multiple lesions and not all plaques develop erosion resulting in occlusive thrombus formation. Since the systemic milieu is the same, we hypothesized that plaque morphological features would be different between eroded ...

    7. Comparison by Optical Coherence Tomography of the Frequency of Lipid Coronary Plaques in Current Smokers, Former Smokers, and Non-smokers

      Comparison by Optical Coherence Tomography of the Frequency of Lipid Coronary Plaques in Current Smokers, Former Smokers, and Non-smokers
      Smoking is associated with high incidence of cardiovascular events including acute coronary syndrome (ACS). We sought to characterize coronary plaques in patients with ongoing smoking using optical coherence tomography (OCT) compared to former smokers and nonsmokers. We identified 465 coronary plaques from 182 subjects who underwent OCT imaging for all three coronary arteries. Subjects were divided into 3 groups: current smokers (n=41), former smokers (n=67) and nonsmokers (n ...

      Interpretation of optical coherence tomography images : The Lancet
      We read with great interest the Clinical Picture reported by Dennis Wong and colleagues (Feb 8, p e11) 1 who took advantage of the unprecedented resolution of optical coherence tomography (OCT) to identify the culprit lesion and guide coronary stenting in a patient with acute myocardial infarction. Over the last decade, OCT has become the method of choice to investigate the mechanisms responsible for acute coronary syndromes. 2 In this ...

    10. Distinct Morphological Features of Ruptured Culprit Plaque for Acute Coronary Events Compared to those with Silent Rupture and Thin-Cap Fibroatheroma: a Combined Optical Coherence Tomography and Intravascular Ultrasound Study

      Distinct Morphological Features of Ruptured Culprit Plaque for Acute Coronary Events Compared to those with Silent Rupture and Thin-Cap Fibroatheroma: a Combined Optical Coherence Tomography and Intravascular Ultrasound Study
      Objectives To identify specific morphological characteristics of ruptured culprit plaques (RCP) responsible for acute events, and compare them with ruptured non-culprit plaques (RNCP) and non-ruptured thin-cap fibroatheroma (TCFA) in patients presenting with acute coronary syndromes (ACS). Background Non-ruptured TCFA and multiple ruptured plaques are detected in the same patients with ACS. It remains unknown whether certain morphological characteristics determine rupture of TCFA and subsequently result in ACS. Methods We analyzed ...

      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 ...
