    2. Deep neural networks for A-line-based plaque classification in coronary intravascular optical coherence tomography images

      Deep neural networks for A-line-based plaque classification in coronary intravascular optical coherence tomography images
      We develop neural-network-based methods for classifying plaque types in clinical intravascular optical coherence tomography (IVOCT) images of coronary arteries. A single IVOCT pullback can consist of 500 microscopic-resolution images, creating both a challenge for physician interpretation during an interventional procedure and an opportunity for automated analysis. In the proposed method, we classify each A-line, a datum element that better captures physics and pathophysiology than a voxel, as a fibrous layer ...

    3. Pre-infarction Angina and Culprit Lesion Morphologies in Patients with a First ST-segment Elevation Acute Myocardial Infarction: Insights from In Vivo Optical Coherence Tomography

      Pre-infarction Angina and Culprit Lesion Morphologies in Patients with a First ST-segment Elevation Acute Myocardial Infarction: Insights from In Vivo Optical Coherence Tomography
      Aims: This study aimed to evaluate the relationship between pre-infarction angina (PIA) and in vivo culprit lesion characteristics as assessed by intravascular optical coherence tomography (OCT) in patients with a first ST-segment elevation myocardial infarction (STEMI). Methods and results: A total of 305 consecutive patients with a first STEMI who underwent OCT imaging of culprit lesions during primary percutaneous coronary intervention (PCI) were prospectively enrolled. OCT findings of the culprit ...

    4. Intracoronary optical coherence tomography: Clinical and research applications and intravascular imaging software overview

      Intracoronary optical coherence tomography: Clinical and research applications and intravascular imaging software overview
      By providing valuable information about the coronary artery wall and lumen, intravascular imaging may aid in optimizing interventional procedure results and thereby could improve clinical outcomes following percutaneous coronary intervention (PCI). Intravascular optical coherence tomography (OCT) is a light-based technology with a tissue penetration of approximately 1 to 3 mm and provides near histological resolution. It has emerged as a technological breakthrough in intravascular imaging with multiple clinical and research ...

    5. Optical coherence tomography evaluation of intermediate-term healing of different stent types: systemic review and meta-analysis

      Optical coherence tomography evaluation of intermediate-term healing of different stent types: systemic review and meta-analysis
      Aims The intermediate-term incidence of strut malapposition (SM) and uncovered struts (US), and the degree of neointimal thickness (NIT) according to stent type have not been characterized. Methods and results All studies of 50 patients in which optical coherence tomography was performed between 6 and 12 months after stent implantation were included. The incidences of SM and US were the co-primary end points, while NIT was the secondary end point ...

    6. Is high pressure postdilation safe in bioresorbable vascular scaffolds? Optical coherence tomography observations after noncompliant balloons inflated at more than 24 atmospheres

      Is high pressure postdilation safe in bioresorbable vascular scaffolds? Optical coherence tomography observations after noncompliant balloons inflated at more than 24 atmospheres
      Objectives Optical coherence tomography (OCT) was used to investigate integrity and expansion of bioresorbable drug-eluting scaffolds (BVS) after high-pressure postdilation (HPPD). Background Because of concerns about the risk of BVS damage, postdilation was not recommended and applied in the existing randomized studies and most registries. Recent real world data suggest incomplete BVS expansion cause higher rates of thrombosis. In vivo confirmation of the safety of high pressure postdilation is of ...

    8. Volumetric assessment of lesion severity with optical coherence tomography: relationship with fractional flow reserve

      Volumetric assessment of lesion severity with optical coherence tomography: relationship with fractional flow reserve
      Aims: Frequency-domain optical coherence tomography (FD-OCT) provides a rapid tomographic scan of a coronary vessel, with an accurate reconstruction of its lumen profile. An FD-OCT-based metric that corresponds more closely with physiological significance of lesions may enable more precise guidance of interventional procedures. The aim of this feasibility study was to evaluate a new method for quantifying coronary lesion severity that estimates hyperaemic flow resistance of branched vessel segments imaged ...

    9. Association Between Proximal Stent Edge Positioning on Atherosclerotic Plaques Containing Lipid Pools and Postprocedural Myocardial Infarction (from the CLI-POOL Study)

      Association Between Proximal Stent Edge Positioning on Atherosclerotic Plaques Containing Lipid Pools and Postprocedural Myocardial Infarction (from the CLI-POOL Study)
      Postprocedural myocardial infarction is an ominous complication of percutaneous coronary intervention (PCI). Despite several patient, lesion, and procedural factors that may affect its occurrence and severity, it is unclear if implanting a stent edge on a coronary lipid pool, as appraised by optical coherence tomography (OCT), adversely affects outcomes. The aim of this study was to assess the association between postprocedural myocardial infarction and the implantation of a stent edge ...

      Transcatheter renal sympathetic ablation for resistant hypertension: in vivo insights in humans from optical coherence tomography
      Hypertension represents a major health problem, with resistant hypertension being defined as uncontrolled blood pressure despite the use of optimal doses of 3 antihypertensive agents . Patients with resistant hypertension often have an increased renal sympathetic nerve activity, and building upon the historical experience with surgical renal sympathetic denervation, transcatheter radiofrequency ablation has been recently proposed . The safety profile of this novel technique appears satisfactory , but there is still limited insight ...

    12. Early vessel healing of the Avantgarde cobalt-chromium coronary stent: the ON-GARDE OCT study

      Early vessel healing of the Avantgarde cobalt-chromium coronary stent: the ON-GARDE OCT study
      Introduction: Uncoverage and malapposition of stent struts at optical coherence tomography (OCT) have been associated with stent thrombosis. Stent uncoverage by OCT is being used as a surrogate to address the propensity of a stent to develop thrombosis. We aimed to appraise early vessel healing in patients with ST-elevation myocardial infarction (STEMI) treated with the novel Avantgarde stent. Methods: Patients with STEMI and multivessel disease were enrolled. The stent deployed ...

    14. Serial Assessment of Coronary Artery Response to Paclitaxel-Eluting Stents Using Optical Coherence Tomography

      Serial Assessment of Coronary Artery Response to Paclitaxel-Eluting Stents Using Optical Coherence Tomography
      Background—The paucity of longitudinal, serial high-resolution imaging studies has limited our understanding of in vivo arterial response to drug-eluting stents. We sought to investigate the human coronary response to paclitaxel-eluting stent implantation, using serial optical coherence tomography assessments. Methods and Results—Thirty patients with at least 2 significant coronary lesions in different vessels were treated with a paclitaxel-eluting stent. The most severe stenosis (lesion A) was treated at the ...
