Abbreviations
Duplicate left anterior descending (LAD) coronary artery
Synonyms
Dual left anterior descending (LAD) coronary artery
Definitions
Rare congenital coronary artery anomaly with 2 LADs: 1 short, 1 long
Short LAD usually originates from LAD proper and terminates high in proximal anterior interventricular vein (AIV) groove
Long LAD has variable origin from either left or right coronary arteries, has variable course outside proximal AIV groove, and reenters distal part of AIV groove to reach cardiac apex
Note that normally, LAD originates from left main coronary artery (LMCA), courses in AIV groove, and gives off diagonal and septal perforators
