Blood passes through a valve before leaving each chamber of the heart. There are four valves within your heart. The heart valves make sure blood flows in only one direction through your heart.

The mitral valve is located between the left upper and lower chambers of the heart. It has two leaflets that open and close similar to a double door.

Stenosis means narrowing of an opening, such as a heart valve. Stenosis of the mitral valve limits the forward flow of blood from the left atrium to the left ventricle. This may cause a back-up of blood and fluid in the lungs. in percutaneous procedure we enter through minimal incision and open the valve using special balloons.
