Pulmonic Stenosis!

Pulmonary Stenosis or pulmonic stenosis is an inherited disease which a person gets from the birth. This disease is the outcome of the retarded development of the fetal heart. If the fetus of the child undergoes retarded heart growth in the first eight weeks of the pregnancy, the child suffers from pulmonary stenosis.

In the normal process, the circulation of blood is from the right ventricle. Blood is pumped from the right side of the heart to obtain oxygen. This pure blood goes to the left side from where it is pumped to the entire body. In the case of pulmonary stenosis, the flow of blood is obstructed and this obstruction is generally caused due to the problem in the functioning of the pulmonary valve. As a result of this obstruction, the heart experiences stress in pumping the blood and it has to labor more to carry on the normal processes. Due to this stress and exertion on the heart, pulmonary stenosis may be caused resulting in at times the failure of your heart. Pulmonary stenosis is generally caused in all the species. It is a congenital disease and can happen to anyone at the time of his fetal development.

Symptoms of Pulmonary stenosis:

The common symptoms of this disease include the jugular venous distention. Another symptom of this disease is cyanosis which causes nail bleeds. The general symptom of this disease is the lowering of the oxygen level of the blood. If your case is not severe, your disease may remain unnoticed for several years, however, in case of severity, it may cause fainting and dizziness.

The medical science has discovered four types of pulmonary stenosis states which are mentioned below:

* Valvar pulmonary stenosis: In this disease, the valve leaf lets of the pulmonary valve becomes thick and obstructs the free flow of the blood.

* Supravalvar pulmonary stenosis: In this disease, the pulmonary artery that is just above the pulmonary valve gets narrowed and it in turn obstructs the free functioning of the pulmonary valve and leads to stress on the heart.

* Subvalvar pulmonary stenosis: In this disease, the thickening of the muscles under the valve area restricts the free functioning of the heart which results in the narrow outflow of the blood from the right ventricle. The heart needs to work harder to pump the blood.

* Branch peripheral Pulmonary stenosis: In this disease, the narrowing takes place in wither the left or the right pulmonary artery. In some cases, both the arteries may get narrowed.

Pulmonary stenosis is an alarming disease which needs to be treated as soon as it is detected or else it may cause the patient's heart to fail. You need to consult a physician once you come to know the presence of this disease in your child.
