What's wrong with the transposition of the great arteries?

summary

Transposition of the great arteries refers to the changes of the relationship between the great vessels caused by developmental malformations, including complete transposition of the great vessels, corrected transposition of the great vessels, double outlet of the right ventricle, transposition of the great vessels with single ventricle, etc. Let's share my experience with you.

What's wrong with the transposition of the great arteries?

Complete transposition of the great vessels is also called right transposition of the great vessels. At this time, the aorta comes from the right ventricle and the pulmonary artery comes from the left ventricle. The aorta is located in the anterior right of the pulmonary artery. Atrial septal defect (ASD), ventricular septal defect (VSD), patent ductus arteriosus (PDA), pulmonary artery stenosis, aortic stenosis, persistent atrioventricular common channel (avcc), tricuspid atresia, etc.

The complete dislocation of the great vessels makes the unoxygenated blood flowing back from the peripheral veins to the right atrium and right ventricle combine and spray directly into the aorta without passing through the lung; Oxygenated blood from the pulmonary vein flows back to the left atrium and left ventricle, then to the pulmonary artery and back to the lung. If there is no communication between large and small cycles, the patient will not survive. The combined existence of atrial septal defect, ventricular septal defect and patent ductus arteriosus is enough to communicate the two circulation, but the blood oxygen content of peripheral arteries is still low. The pathophysiological changes depend on the size of these communication and whether there is pulmonary artery stenosis at the same time.

Cyanosis occurs immediately after birth, feeding difficulties in infancy, slow weight gain, asthma, cough, respiratory tract infection, and heart failure often occurs within four months. In patients with patent ductus arteriosus, cyanosis of the lower body is mild, and pestle fingers (toes) often appear after half a year old.

matters needing attention

In the diet must also control the salt intake, do not eat spicy food such as coffee, strong tea, you can eat more cereals such as cereals, oats or soybeans, you can drink more water or milk, but do not drink carbonated drinks.
