Pulmonic stenosis is a heart condition which is usually congenital in nature. It refers to the narrowing down of the pulmonary valve as a result of which there is obstruction in the blood flow to the lungs from the heart. This condition can cause serious problems for your heart. It can result in the accumulation of fluids in the chest cavity or the abdomen and a shortage of blood supply to other parts of the body. On account of this condition people often faint while performing physical work as the body needs more oxygen and cannot obtain it on account of the poor blood supply.
Causes
Myxomatous plaques are formed in the right ventricles due to carcinoids which constrict the ring of the pulmonary artery, thus blocking the passage of the blood. Very rarely cardiac tumors can also be the reason for the disease of blood obstruction.
Symptoms
On severe conditions there will be a slight noise near the heart when one breathes because of the narrowing of the pulmonary valve. Other symptoms are pain the left part of the chest, difficulty in breathing and heaviness in the area of the chest.
There are three types of pulmonic stenosis. These are valvular PS, subvalvular PS, and peripheral PS. All of them affect the valves of the right chamber of the heart preventing blood flow to the right ventricles from where heart moves to other parts of your body.
Treatments
Pulmonic stenosis is generally treated by surgeries called valvotomy. Since 1982, balloon valvuloplasty has been carried out as a treatment for the problem. Another surgery called the valvular angioplasty is also used to treat more complex cases.
