Dual left anterior descending artery - a clinical entity in search of an identity: A novel classification.

A dual left anterior descending artery (LAD) is not an uncommon anomaly of the coronary arterial system. The earlier classifications by various authors lacked standardization and uniformity and are too complex for clinical usage. Therefore, a new classification in the form of coding system is proposed to facilitate the identification and reporting of the anomaly by the cardiologists to maintain uniformity in reporting, which aids in adequate planning of the revascularization strategies in patients with symptomatic coronary artery disease involving the dual LAD system.
