title: Types of interventricular septal branches of the anterior interventricular branch of the left coronary artery in human hearts.
abstract: The study aimed at determining types of interventricular septal branches stemming from the anterior interventricular branch of the left coronary artery. The studies were performed on 28 preparations of human heart aging 29 to 88 years. The technique of direct preparation was applied using a dissecting microscope. The conducted observations indicate that septal vessels of the anterior interventricular branch follow one of the three main patterns. Type I involves a dominant septal trunk, exhibiting its own branching and few fine septal branches, type II exhibits a single dominant unbranched ramus and multiple fine branches, while type III includes two dominant, unbranched septal rami of the septum and small number of fine septal branches. In the cases examined by us type III pattern was most frequent. No relationship was detected between the type of coronary vessels of the heart and the type of septal vessels of the anterior interventricular branch.
