Q24: Other congenital malformations of heart
Q24.3: Pulmonary infundibular stenosis
Major, important blood vessels branch out of the heart. The main artery (aorta), originating from the left lower chamber (ventricle) of the heart, supplies the whole body with oxygen-rich blood. The right ventricle pumps oxygen-poor blood through the pulmonary artery to the lungs, where the blood is then enriched with oxygen.
The muscular wall of the heart has thickened at the exit of your right lower heart chamber (ventricle). This means that blood is not able to flow properly into your pulmonary artery and that your heart has to work harder to pump blood into the lungs.
You don’t often get many symptoms with this defect. When the heart has to work a lot harder, fluid can build up in the body. This may result in the liver being damaged or the legs swelling up, for example. When less blood can flow to the lungs, some of the areas of the body may not get enough oxygen. You may then become tired quickly or have shortness of breath. It may also sometimes cause you to experience chest pain or dizziness.
