    Accidental right coronary artery occlusion during arteriography can cause distinct venous filling patterns, mimicking disease. Awareness of these artifacts is crucial for accurate diagnosis and patient safety.

    Area of Science:

    • Cardiology
    • Interventional Radiology

    Background:

    • Coronary arteriography is a key diagnostic tool.
    • Accidental catheter-induced coronary artery occlusion can occur.
    • Recognizing artifacts is vital to avoid misdiagnosis.

    Purpose of the Study:

    • To analyze arteriographic findings of accidental right coronary artery occlusion.
    • To differentiate these findings from actual coronary artery disease.
    • To inform angiographers about potential artifacts.

    Main Methods:

    • Retrospective analysis of 18 studies with accidental right coronary artery occlusion.
    • Comparison with 25 normal and 20 coronary artery stenosis studies.
    • Detailed review of arteriographic images for specific filling patterns.

    Main Results:

    • Occlusion arteriograms showed early anterior cardiac vein filling.
    • Retrograde filling of the left circumflex artery was occasionally observed.
    • No serious complications were noted in the occlusion group.

    Conclusions:

    • Distinct venous filling patterns are artifacts of right coronary artery occlusion.
    • These patterns should not be mistaken for pathological conditions.
    • Angiographer awareness can prevent misinterpretation and ensure patient safety.
