    2. Longitudinal Stent Deformation: Precise Diagnosis With Optical Coherence Tomography

      Longitudinal Stent Deformation: Precise Diagnosis With Optical Coherence Tomography
      Longitudinal stent deformation (LSD), defined as the distortion or shortening of a stent in the longitudinal axis following successful stent deployment, has been recognized as an important complication of coronary angioplasty. It is caused by impact on a deployed stent by a device (such as a guide catheter or guide-catheter extension) or secondary devices (such as postdilation balloons) as a result of guidewire bias as well as the inherent mechanical ...

    3. RECURRENT ACUTE RETINAL PIGMENT EPITHELIITIS: SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY AND OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY FEATURES

      RECURRENT ACUTE RETINAL PIGMENT EPITHELIITIS: SPECTRAL DOMAIN OPTICAL COHERENCE TOMOGRAPHY AND OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY FEATURES

Spectral domain OCT and OCT angiography images were acquired with Cirrus 5,000 spectral domain OCT. Results: Although acute retinal pigment epitheliitis is described as a benign, self-limited pathology, as ...

    4. Optical Coherence Tomography for the Early Detection of Coronary Vascular Changes in Children and Adolescents After Cardiac Transplantation

      Optical Coherence Tomography for the Early Detection of Coronary Vascular Changes in Children and Adolescents After Cardiac Transplantation
      Download figure Open in new tab Download powerpoint Abstract Objectives This study sought to describe the initial findings from the International Pediatric Optical Coherence Tomography (OCT) registry in pediatric heart transplant recipients. Background Cardiac allograft vasculopathy (CAV) is a common cause of late graft failure and mortality in pediatric heart transplant recipients. Early diagnosis may improve outcomes. OCT is a high-resolution intravascular imaging technique that has the potential to identify ...

    5. Use of OCT Angiography in Choroidal Melanocytic Tumors

      Use of OCT Angiography in Choroidal Melanocytic Tumors
      Objective. To describe OCTA findings in choroidal melanocytic tumors, especially the microcirculation patterns, and to try to correlate with the histopathological studies. Methods. Cross-sectional, comparative, observational study. 70 cases, including 55 choroidal nevi and 15 choroidal melanomas. Three different observers evaluated specific variables in the choriocapillaris layer on AOCT images and searched for images which described histopathologic vascular patterns, and also, a general description of the images was made. Complementary ...

    6. OCT Angiography: Assessment of Retinal Ischemia in Susac's Syndrome

      OCT Angiography: Assessment of Retinal Ischemia in Susac's Syndrome
      Descriptive study of two patients affected by Susac's syndrome (SuS) focusing on the chronic retinal tissue damage assessed by optical coherence tomography (OCT) and OCT angiography (OCTA). To the authors' knowledge, this is the first case series reporting OCTA in SuS. OCTA imaging revealed secondary hypoxia due to branch retinal artery occlusion of the deep capillary plexus, with additional involvement of the superficial capillary network in one case. OCTA ...

    7. Visual Outcomes, Visual Fields, and Optical Coherence Tomography in Paediatric Craniopharyngioma

      Visual Outcomes, Visual Fields, and Optical Coherence Tomography in Paediatric Craniopharyngioma
      Ten patients with craniopharyngioma treated for the first time when younger than 18 were included. This study reviews the visual outcomes and provides information on visual field (VF) and optical coherence tomography (OCT) examination of craniopharyngioma. The best kappa concordance coefficients between VF and OCT parameters of atrophy were obtained for the ganglion cell (GC) thickness and the mean retinal nerve fibre layer (RNFL) thickness. The agreement between GC colour ...

    8. Optical Coherence Tomography in Thromboembolic Pulmonary Hypertension

      Optical Coherence Tomography in Thromboembolic Pulmonary Hypertension
      Thromboembolic pulmonary hypertension is caused by thrombotic obstruction of the pulmonary artery tree after a thromboembolic event. Ifthe thrombotic event does not resolve, fibrotic changes associated with vascular remodeling occur, leading to increased pulmonary resistance. An 80-year-old man was diagnosed with severe hypertension by echocardiography after signs and symptoms of acute pulmonary thromboembolism 2 years earlier. Cardiac catheterization found a pulmonary pressure of 80/30 mmHg (mean, 47 mmHg), with ...

    9. Neoatherosclerosis as the Cause of Very Late Bare-metal Stent Restenosis: Optical Coherence Tomography Evaluation

      Neoatherosclerosis as the Cause of Very Late Bare-metal Stent Restenosis: Optical Coherence Tomography Evaluation
      To the Editor, A man aged 49 years, ex-smoker with a family history of premature ischemic heart disease, attended the emergency department after 1 month with clinical symptoms of progressive angina following even minimal exertion. In 2001, he had presented non-Q wave acute myocardial infarction and undergone conventional bare-metal stent (BMS) implantation in the mid left anterior descending artery. In 2007, a coronary angiogram for exertional angina showed no stent ...

    10. Stent Thrombosis in Ostial Lesion: Diagnosis and Treatment Guided by Optical Coherence Tomography

      Stent Thrombosis in Ostial Lesion: Diagnosis and Treatment Guided by Optical Coherence Tomography
      To the Editor , Optical coherence tomography (OCT) is an intracoronary diagnostic technique of particular interest for characterization of the atheromatous plaque and assessment of the outcome of stenting by percutaneous coronary intervention. We present a case of stent thrombosis in which OCT provided very useful information for arriving at the diagnosis, understanding the thrombotic mechanism, deciding on the most appropriate therapeutic strategy, and guiding percutaneous coronary intervention. The patient was ...

    11. Usefulness of intracoronary imaging techniques in the percutaneous treatment of in-stent restenosis

      Usefulness of intracoronary imaging techniques in the percutaneous treatment of in-stent restenosis
      We report a case of very late bare-metal stent restenosis, in which assessment by two intracoronary imaging techniques (intravascular ultrasound and optical coherence tomography) revealed the underlying mechanism (neoatherosclerosis) and facilitated percutaneous treatment (direct bare-metal stent-in-stent). We also take the opportunity to briefly describe the advantages and limitations of both techniques in this pathology.

    12. Utility of optical coherence tomography and intravascular ultrasound for the evaluation of coronary lesions

      Utility of optical coherence tomography and intravascular ultrasound for the evaluation of coronary lesions
      Optical coherence tomography (OCT) and intravascular ultrasound (IVUS) are imaging methods used in the diagnosis of coronary lesions. IVUS is widely used in interventional cardiology laboratories, but OCT is now increasingly used. Conventional coronary angiography can identify different types of coronary lesions but sometimes is unable to diagnose them correctly. Both intravascular imaging methods are useful for better interpretation of these lesions, and can accurately diagnose ruptured plaques, thrombosis, stent ...

      Renal artery fibromuscular dysplasia: in vivo optical coherence tomography insights
      A 66-year-old woman with long-term essential hypertension presented with poorly controlled blood pressure in spite of six antihypertensive drugs. Percutaneous renal denervation was indicated as a treatment of resistant arterial hypertension. Renal angiography showed strings of beads appearance characteristic of fibromuscular dysplasia (FMD) in the mid-segment of the right

      Potential Use of Optical Coherence Tomography and High-Frequency Ultrasound for the Assessment of Nail Disease in Psoriasis and Psoriatic Arthritis
      Background: Psoriatic nail disease is increasingly recognised to be of major clinical and research relevance. Clinical assessment remains the current gold standard for its evaluation. Objective: We compared optical coherence tomography (OCT) and ultrasound (US) for nail disease assessment in psoriatic disease. Methods: 18 patients with at least one involved nail and 12 healthy controls were scanned using OCT; psoriatic patients also had an US scan (using a linear probe ...
