Because these vessels and their branches supply the heart, any dysfunction or disease that affects them can cause serious, sometimes fatal complications. Coronary arterial anastomoses occur throughout the heart and are especially numerous within the interventricular and interatrial septa, at the apex of the heart, at the crux, over the anterior surface of the right ventricle, and between the sinus-node artery and the other atrial arteries.
