    This study demonstrates the feasibility of in vivo coronary angioscopy, a new technique for directly visualizing coronary arteries. This innovative approach holds potential for diagnosing and treating cardiovascular diseases.

    Area of Science:

    • Cardiovascular medicine
    • Medical imaging
    • Surgical innovation

    Background:

    • Direct visualization of coronary arteries is limited.
    • Existing diagnostic methods have limitations in assessing intravascular anatomy and disease.

    Purpose of the Study:

    • To assess the feasibility of in vivo coronary angioscopy.
    • To evaluate a novel angioscopic technique for direct visualization of coronary arteries.

    Main Methods:

    • Utilized a 1.8 mm angioscope in optically clear liquid-filled vessels.
    • Conducted trials in postmortem canine and human coronary arteries.
    • Achieved in vivo intraluminal visualization in dogs and during open-heart surgery in patients.

    Main Results:

    • Demonstrated the feasibility of in vivo coronary angioscopy.
    • Showcased the potential clinical usefulness of direct intravascular visualization.
    • Established an analogy to endoscopy for other organ systems.

    Conclusions:

    • In vivo coronary angioscopy is feasible and clinically useful.
    • This technique offers direct visualization of intravascular anatomy and disease.
    • Coronary angioscopy represents a significant advancement in cardiovascular diagnostics.
