Q26: Congenital malformations of great veins
Q26.4: Anomalous pulmonary venous connection, unspecified
You need lungs to breath. When we breathe in, oxygen enters the lungs and accumulates in the blood. This blood then flows to the heart. The heart then pumps the oxygen-rich blood throughout the body. All of the organs are supplied with oxygen as a result. The blood vessels from the lungs to the heart are called pulmonary veins. Normally, blood flows from the lungs into the left side of the heart through the pulmonary veins. From there, it is pumped into the body.
Your pulmonary veins did not develop properly before you were born. With this defect, blood flows from the lungs through the pulmonary veins into the right side of the heart instead of the left side. From the right side of the heart, some of the blood is then pumped directly through the lungs again. This creates additional blood flow between the heart and the lungs. The body may not be adequately supplied with oxygen.
You may have various symptoms with this disease. It may inhibit normal growth during childhood. You may also feel weak or be short of breath. If the heart comes under a lot of strain as a result of the additional blood flow, you can become seriously ill.
