Some anatomical aspects of the anterior interventricular artery (anterior descending) of the human heart

The coronary arteries of 50 human hearts were studied. Muscular overbridging appeared in 19 (38 per cent) of the anterior interventricular arteries and was more frequent on the proximal third of the artery (52.6 per cent) which is usually 11.13 n 2.96 cm long. The middle length of the bridges was 2.8 n 1.6 cm. The number of collateral branches of the interventricular artery in both ventricular chambers varied widely from 2 to 20 with a mean of 8.53 n 4.39. The main septal branch emerged 3.85 n 1.12 cm from the origin the anterior interventricular artery. The other septal branches were 9.9 + 1.55 in number. Anastomosis between anterior and posterior interventricular arteries was observed in 76 per cent of the cases studied. Based on our results, we speculate about the behaviour of coronary arteries in terms of their course. (AU).
