. DISTRIBUTION OF GROWTH OF THE MAIN BRANCHES OF CORONARY ARTERY IN MONGOLIAN CHILDREN AGED FROM 0-16. .

The finer details may be appropriate for the interest of anatomists and radiologists, In clinical practice, however, surgeons need only to be concerned with some of the more constant and important features. The branching characteristics of the coronary arterial tree plays an important role in cardiac surgeries, such as a heart pacemaker implantation, angioplasty, and even in stent placement. [1, 2]. We assessed the branching of arteria coronaria dextra (right coronary arteries), ramus circumflexus (circumflex branches of coronary artery), ramus interventricularis anterior (anterior interventricular branches of left coronary artery). In newborns lateral branches of the right coronary artery were short, scattered and curved. The main branch of the right coronary arteries was short at the base of the heart. Left, left dominant, right, right dominant, identical those 5 types of heart blood supply was consisted gradually in children aged from 3 to 16. The estimated measurements of coronary artery was permanent in children aged from 4 to 16. In newborn, the elastic membrane of the vessels was not occured in all branches of the coronary artery. Five type /Left, left dominant, right, right dominant, identical/ of heart blood supply was predominantly in adolescents. The measurements were resemble of the left and right coronary in adolescents. - See more at: .
