This congenital heart disease is one of the most severe and most common of the defects of the heart, accompanied by cyanosis (blueness). Its frequency from 12 to 20% of all congenital heart defects. Chalice in newborn males.
Transposition of great arteries is a position of blood vessels, when the aorta moves away from the right heart and pulmonary artery from the left. Their normal location of the opposite. With the full transposition of the aorta outgoing from the right ventricle of the heart carries the venous blood, which, after passing through the arteries, capillaries, veins, returns to the right atrium and right ventricle. The pulmonary artery carries blood from the left ventricle to the lungs and back into the left atrium. Thus, large and small communities do not communicate with each other. In a large circulation circulating venous blood is not oxygenated.
Such a condition is incompatible with life. And the patient's life depends on the hole between the atria or between ventricles. Typically, this message is not enough. And the body tries to compensate by increasing the volume of blood ejected ventricles, leading to an overload of the heart and eventually to heart failure.
From the first days of life the child appears sharp cyanosis of the body. The general condition is satisfactory in the early days. Then gradually increase the size of the heart develops. There are shortness of breath, increased heart rate. Increased liver. There is swelling. Over the area of the heart auscultated systolic murmur. An electrocardiogram revealed the load on the right of the heart, at least on the left. On radiographs are changes in the lungs, enlarged heart size, heart in the form of "egg." Angiography is determined by the discharge of the aorta from the right ventricle and the pulmonary artery from the left.
Treatment. There are different types of surgical interventions with heart defects. At present, replacement is performed in some places of the aorta and pulmonary artery. The operation is called the arterial switch.
