Dual left anterior descending artery with anomalous left anterior descending artery from pulmonary artery: double trouble


 Anomalous origin of left anterior descending artery (LAD) from pulmonary artery (PA) with dual LAD from left sinus is an extremely rare coronary anomaly. The diagnostic challenge lies in differentiating this from a coronary cameral fistula. Surgical reimplantation of the anomalous LAD is recommended to prevent risk of myocardial ischaemia and ventricular arrhythmias.
