    Coronary endoscopy using ultrathin fibre endoscopes shows promise for visualizing coronary vascular changes and atherosclerosis. While experimental, this technique offers a new dimension in morphological assessment of blood vessels.

    Area of Science:

    • Cardiovascular Medicine
    • Medical Imaging
    • Surgical Technology

    Background:

    • Atherosclerosis and vascular disease require accurate diagnostic methods.
    • Current imaging techniques may have limitations in visualizing intricate vessel morphology.
    • Minimally invasive endoscopic approaches are being explored for vascular assessment.

    Purpose of the Study:

    • To evaluate the feasibility and efficacy of ultrathin fibre endoscopes for coronary and peripheral vessel endoscopy.
    • To assess the visualization capabilities of this technique in different vascular beds and clinical scenarios.
    • To determine the potential of coronary endoscopy in morphological assessment of vascular changes.

    Main Methods:

    • Utilized two ultrathin fibre endoscopes (1.4 or 1.8 mm diameter, 120 cm working length).

  • Performed endoscopy on four groups: cadaver hearts, peripheral vessels in patients, during balloon-catheter dilatation, and intraoperatively.
  • Assessed visualization success, vessel pathology (stenosis, atheromatous changes), and procedural safety.

    • Main Results:

    • Successful visualization of normal and diseased vessels in cadaver hearts and peripheral arteries.
    • Endoscopy visualized stenosis or occlusion in 2 out of 5 successful coronary endoscopy cases during balloon dilatation.
    • Intraoperative visualization of vessels, including distal course and anastomosis sites, was achieved in 7 out of 9 patients.
    • No serious adverse events were reported.

    Conclusions:

    • Coronary and peripheral vessel endoscopy with ultrathin fibre endoscopes is a feasible experimental technique.
    • The method provides a new dimension for morphological assessment of coronary vascular changes.
    • Further research and development are needed to establish its clinical utility.
