[Age characteristics of the projections of the heart and its foramina on the anterior thoracic wall in newborn infants and children younger than 7 years of age].

Projections of the heart borders and its orifices on the anterior thoracic wall have been studied in 122 corpses of newborns and children up to 7 years of age by means of visiography, dioptrography and preparation methods. In parallel with changes occurring in the cardiac borders, projections of the vena cava, the pulmonary trunk orifices, as well as projections of both atrioventricular orifices change, too. The level of their projections is gradually going down. For example, in the pulmonary trunk orifices from the II rib level drops down to the III rib, the aortic orifices--from the II rib level down to the IV rib, the right atrioventricular orifice--from the III rib level down to the V rib, and the left one--from the III rib level down to the IV intercostal level. While the child is growing, the heart is turning around the sagittal, vertical and frontal axis. Department of Operative Surgery and Topographic Anatomy, M. I. Kalinin Medical Institute, Andizhan.
