PULMONARY ATRESIA WITHOUT VSD FOR CHILDREN

Pulmonary atresia is a condition in which the heart lacks a pulmonary valve. This surgery improves blood flow through the heart and out to the lungs.

In pulmonary atresia, the pulmonary valve doesn’t form right. So there is no link between the right ventricle and the pulmonary artery. As a result, only a little blood can get to the lungs through an extra blood vessel. Instead of going to the lungs, blood that is low in oxygen travels through a hole in the wall between the right and left atrium. That causes the blood going out to the body to be very low in oxygen.
