Seq#7500 (Coronary Circulation Dominance)

Video Transcription

Video Summary

Coronary circulation dominance is determined by the origin of the posterior descending artery and posterolateral artery, affecting perfusion of the left ventricle's inferior surface. Variations in coronary anatomy are common in patients undergoing coronary catheterization. Dominance can be categorized as left, right, or codominant based on where these arteries arise. The coding for sequence 7500 reflects this information from medical records or physician documentation. In cases of heart transplant history, dominance should be based on the new heart's circulation. The registry accepts values consistent with records from over 30 days prior to the procedure.
