anterior interventricular branch of left coronary artery

[TA]
terminal branch (with circumflex coronary artery of left coronary artery); descends in anterior interventricular groove close to apex, anastomosing with posterior interventricular artery. Supplies most of sternal aspect of ventricles and anterior two thirds of interventricular septum, including atrioventricular bundle of conducting tissue.
