    3. Intravascular imaging and guide catheter detection methods and systems

      Intravascular imaging and guide catheter detection methods and systems
      In part, the disclosure relates to computer-based methods, devices, and systems suitable for detecting a delivery catheter using intravascular data. In one embodiment, the delivery catheter is used to position the intravascular data collection probe. The probe can collect data suitable for generating one or more representations of a blood vessel with respect to which the delivery catheter can be detected.

    5. Method, apparatus, and system to identify branches of a blood vessel

      Method, apparatus, and system to identify branches of a blood vessel
      In part, the disclosure relates to an automated method of branch detection with regard to a blood vessel imaged using an intravascular modality such as OCT, IVUS, or other imaging modalities. In one embodiment, a representation of A-lines and frames generated using an intravascular imaging system is used to identify candidate branches of a blood vessel. One or more operators such as filters can be applied to remove false positives ...

    6. Morphological Parameters of In-stent RESTenosis Assessed and Identified by OCT

      Morphological Parameters of In-stent RESTenosis Assessed and Identified by OCT
      The statistical risk of intrastent stenosis has fallen considerably with the emergence of latest generation coated stents (drug-eluting stents: DES). The number and clinical lifespan of stents implanted over the last twenty-five years, however, explain the fact that restenosis remains a not unusual clinical problem which is expressed as a recurrence of angina or of an acute coronary syndrome (ACS). The mechanisms involved in this restenosis are multifactorial in nature ...

    7. Randomized Comparison Between Everolimus-Eluting Bioresorbable Scaffold and Metallic Stent Multimodality Imaging Through 3 Years

      Randomized Comparison Between Everolimus-Eluting Bioresorbable Scaffold and Metallic Stent Multimodality Imaging Through 3 Years
      Objectives The aim of this study was to investigate the vascular responses and fates of the scaffold after bioresorbable vascular scaffold (BVS) implantation using multimodality imaging. Background Serial comprehensive image assessments after BVS implantation in the context of a randomized trial have not yet been reported. Methods In the ABSORB Japan trial, 400 patients were randomized to a BVS (n = 266) or a cobalt-chromium everolimus-eluting stent (n = 134). Through 3 ...

    8. Guidewire detection systems, methods, and apparatuses

      Guidewire detection systems, methods, and apparatuses
      In part, the disclosure relates to methods of guidewire detection in intravascular data sets such as scan lines, frames, images and combinations thereof. Methods of generating one or more indicia of a guidewire in a representation of blood vessel are also features of the disclosure. A carpet view is generated in one embodiment and regions of relatively higher contrast are detected as candidate guidewire regions. In one embodiment, the disclosure ...

    9. Detection of and validation of shadows in intravascular images

      Detection of and validation of shadows in intravascular images
      In part, the disclosure relates to shadow detection and shadow validation relative to data sets obtained from an intravascular imaging data collection session. The methods can use locally adaptive thresholds and scan line level analysis relative to candidate shadow regions to determine a set of candidate shadows for validation or rejection. In one embodiment, the shadows are stent strut shadows, guidewire shadows, side branch shadows or other shadows.

    11. In-Stent Restenosis Lesion Morphology Related to Repeat Stenting Underexpansion as Evaluated by Optical Coherence Tomography

      In-Stent Restenosis Lesion Morphology Related to Repeat Stenting Underexpansion as Evaluated by Optical Coherence Tomography
      Aims: To use optical coherence tomography (OCT) to predict newly implanted stent expansion for treatment of in-stent restenosis (ISR). Methods and results: With OCT-guidance, 143 ISR lesions were treated with a new stent. Stent underexpansion was defined as minimum stent area (MSA) 4.5mm 2 and MSA/average of reference lumen area 70%. New stent underexpansion was found in 33 lesions (23%), had a smaller old stent MSA (4.13 ...
