    1. Comparison of optical coherence tomography and intravascular ultrasound for the assessment of in-stent tissue coverage after stent implantation

      Comparison of optical coherence tomography and intravascular ultrasound for the assessment of in-stent tissue coverage after stent implantation
      At present there exists no direct comparative data for the detection of in-stent tissue coverage as assessed by intravascular ultrasound (IVUS) and optical coherence tomography (OCT) in clinical settings. To explore this subject, we investigated the correlation between the IVUS and OCT measurements derived from a contemporary population.

    2. Optical Coherence Tomographic Results at Six-Month Follow-Up Evaluation of the Catania Coronary Stent System With NanoThin Polyzene-F Surface Modification (from the Assessment of The LAtest Non-Thrombogenic Angioplasty Stent [atlanta] Trial)

      Drug-eluting stents were devised as an answer to restenosis, but research has shown that the eluting drug can interfere with the blood vessel's healing process, thus increasing the risk of stent thrombosis. A stent coated with the new proprietary polymer Polyzene-F, is a novel technical solution that promises to decrease in-stent restenosis and tackle the risk of thrombosis. Fifty-five patients were enrolled in the first clinical human study (ATLANTA registry), addressing the short-term follow-up results of the CATANIA stent with Polyzene-F. As a part of the study protocol, 15 patients were randomly assigned to optical coherence tomographic (OCT) examination ...

    3. From Bench to Bedside - A Novel Technique of Acquiring OCT Images

      Background Optical coherence tomography (OCT), a high resolution intravascular imaging technique, requires blood displacement for reliable image acquisition and the current technique uses a soft occlusion balloon plus saline injection in the coronary artery. A non-occlusive technique based on manual infusion of a viscous iso-osmolar solution has been developed and tested and validated through a 2-phase study. Methods and Results OCT assessment was performed with the M2 LightLab OCT (LightLab Imaging, Westford, MA, USA) image-wire in 3 swine by infusing 30 ml of each of 3 solutions differing in viscosity, osmolarity and electrolytic composition (A: iodixanol 320 and Lactated Ringer ...

    4. Safety and feasibility of a new non-occlusive technique for facilitated intracoronary optical coherence tomography (OCT) acquisition in various clinical and anatomical scenarios

      Safety and feasibility of a new non-occlusive technique for facilitated intracoronary optical coherence tomography (OCT) acquisition in various clinical and anatomical scenarios
      To facilitate OCT images acquisition we developed a novel, simplified, non-occulsive technique based on manual infusion of a viscous isosmolar solution. The aims of the present study was to address the safety and efficacy of non-occulsive OCT images acquisition modality in a patient population with comples coronary lesions, and in various clinical sceanarios.
