<h3>What is pulmonary artery stenosis? </h3>
The pulmonary artery is responsible for carrying the deoxygenated blood from the right ventricle of the heart to the lungs to get oxygenated.
Pulmonary artery stenosis is a condition in which the pulmonary artery gets narrowed or blocked. Therefore, blood flow from the heart to the lungs is hampered.
This creates pressure on the walls of the heart. Also, if blood flow towards the lungs is hampered, the heart will not receive the required amount of oxygen. All of this will lead to damage to the heart muscles over the course of time.
