The human heart has four different valves – mitral, aortic, tricuspid and pulmonic valves. The function of these four valves is to ensure that the blood flows only in one direction. These valves are strategically located to control the flow of blood from one chamber of the heart to another and finally to the outside of the heart through the artery.
The mitral and the tricuspid valve control the flow of blood from the atria to the ventricles. The aortic and the pulmonary valve, on the other hand, control the flow of blood from the ventricles to the outside of the heart.
There are certain types of heart valve diseases that warrant the need for heart valve replacement. Aortic stenosis and mitral regurgitation are two such conditions that may prove deadly if not treated on time.
Aortic valve and mitral valve are the two valves that get damaged most commonly due to several reasons. The other two valves – tricuspid and pulmonary – rarely get damaged in a person’s lifetime. Heart valve replacement can treat both these conditions.
Depending on the heart disease that the patient has, the following types of heart valve replacement surgeries can be conducted in India:
This surgery is for patients with faulty or damaged aortic valve or aortic stenosis.
This surgery is for patients with faulty or damaged mitral valve or mitral regurgitation.
This surgery is for patients with problems in both the aortic and the mitral valve.
