coronary artery anomaly classification
Systematic categorization of congenital coronary artery variations based on origin, course, and hemodynamic significance.
Full Definition
Coronary artery anomaly classification systems organize congenital coronary variations into standardized categories to facilitate communication, risk assessment, and management decisions. The most widely used classification divides anomalies into: 1) anomalies of origination and course (including anomalous aortic origin, single coronary artery, and coronary arising from pulmonary artery); 2) anomalies of intrinsic coronary anatomy (myocardial bridges, coronary fistulae); and 3) anomalies related to congenital heart disease. Further subcategorization considers whether the anomalous vessel courses between the great vessels (potentially malignant) or takes a benign pathway. This classification helps determine clinical significance, need for further evaluation, and appropriate management strategies.
Usage
Usage note: Specify the classification system used (e.g., Angelini, ACC/AHA) when applicable.
