CV ASC Registry Education-Seq#7500 (Coronary Circulation Dominance)

Video Transcription

Coronary circulation dominance is looking to capture the greater contributor to the perfusion distribution of the inferior surface of the left ventricle.  Patients that arrive for a coronary catheterization will more often than not have different coronary anatomy.  This data element can reflect that concept by looking at the posterior descending artery origin and distribution.  If the posterior descending artery and posterolateral artery arise from the left circumflex, you would capture this as left and vice versa.  Codominant captures a distribution where the posterior descending artery arises from the right and the posterolateral artery arises from the left, creating an equal distribution  of the inferior surface of the left ventricle. Sequence 7500 coronary circulation dominance can be coded based on descriptive documentation  that meets the definitions found in the data dictionary or on physician documentation alone, such as the patient is left dominant, decoded as left.  Because dominance does not change, the registry will accept the value that is acceptable to code sequence 7500 from information found in a medical medical record that is greater  than 30 days prior to the procedure. The only exception to this rule is that if the patient has a history of a heart transplant,  we want sites to ensure that they're reflecting dominance as reflected in the new heart.

Video Summary

Coronary circulation dominance focuses on identifying the main supplier to the inferior left ventricle surface during coronary catheterization. Patients usually present with diverse coronary anatomy, reflected through the origin and distribution of the posterior descending artery. This can be categorized as left, right, or codominant based on where these arteries arise from, influencing perfusion distribution. The registry codes this information using detailed documentation from the data dictionary or physician notes. Dominance remains constant unless the patient has had a heart transplant, in which case the new heart's dominance determines the coding. This approach ensures accuracy in capturing coronary circulation dominance for medical records.
