    Coronary angioscopy allows direct visualization of coronary arteries. However, technical limitations like scope flexibility and image distortion currently hinder its widespread clinical use for disease identification.

    Area of Science:

    • Cardiology
    • Medical Imaging
    • Interventional Cardiology

    Background:

    • Direct visualization of the coronary artery lumen can aid in disease identification.
    • Coronary angioscopy offers potential for direct inspection of luminal cross-sections.

    Purpose of the Study:

    • To assess the feasibility of introducing an ultrathin fiberscope into the coronary artery for angioscopy.
    • To evaluate the potential of coronary angioscopy for direct disease visualization.

    Main Methods:

    • A 5F Olympus Ultrathin fiberscope was introduced into the right coronary artery in five patients.
    • A modified 8.3F guiding catheter was used to facilitate coaxial passage of the angioscope.
    • Coronary lumen visualization was achieved using saline injection in three patients.

    Main Results:

    • White atheromatous plaque was visualized near obstructions in all successfully visualized cases.
    • Scope flexibility issues prevented passage to the catheter tip in two patients.
    • Image distortion and lack of angulation limited quantitative evaluation and proximal segment access.

    Conclusions:

    • Coronary angioscopy shows promise for direct luminal inspection and disease identification.
    • Technical challenges including scope flexibility, image quality, and angulation need to be resolved.
    • Further development is required before widespread clinical application of coronary angioscopy.
