2 Cases of Dual Left Anterior Descending Coronary Artery

ABSTRACT

"Dual LAD" was defined as the early bifurcation of the proximal LAD into two vessels a short LAD which remained in the anterior interventricular sulcus and does not reach the apex, and a long LAD which leaves the anterior interventricular sulcus only to return to the distal sulcus and continue to the apex. Recognition of "Dual LAD" is essential to prevent errors of interpretation of the coronary arteriogram and for planning of optimal surgical therapy. We report 2 cases of "Dual LAD" with the review of the literatures.
