Valvular heart disease

 Valvular heart disease:
Valves are flap-like structure present at the openings of the atria into the ventricles, and at the openings into the large blood vessels arising from the heart. They prevent the back-flow of the blood as it passes (or is pumped) through the heart chambers. Any structural abnormalities of these valves bring about multifold changes in the dynamics of blood flow.
Common terms for valvular defects seen are:
a) Stenosis: or narrowing of the lumen because the valves do not open properly. This means that the heart has to pump with added force to make the blood pass through the lumen.
b) Atresia: this defect means that the valves do not develop correctly. They are ill-formed and mostly the lumen appears completely closed. So there is no opening from which the blood can pass through.
c) Regurgitation: here the valves do not close properly. Hence, there is regurgitation or back-flow of the blood pumped, into the cambers.
The most common valvular defect encountered is: Pulmonary valve stenosis.
Through this valve, the blood flows from the right ventricle to the lungs where it picks up oxygen. When the valve is stenosed, the severity ranges from mild to severe. Mild forms require no treatment. Just occasionally, an abnormal heart sound (murmur) can be heard. Correction of the condition when necessary, it done by a catheter procedure.
