Can the location of the large septal artery be predicted

The aim of this study is to establish anatomical landmarks for the trajectory of the large septal artery. Thirty hearts were dissected, 20 of which had no cardiac pathology and the remaining with different cardiac conditions. One large septal artery was located in 27 of these hearts, two large septal arteries in 2 and three large septal arteries in 1. For all cases there existed one large septal artery in the lower border of the anterior limb of the septomarginal trabecula. When more than one large septal artery was encountered, the first was located within the subendocardial outflow tract of the left ventricle, the second was in the lower border of the anterior limb of the septomarginal trabecula and the third 1.5 cm below the second.
