Mitral Valve In Valve Implantation

 

About

Mitral valve is one of the four valves present in the heart. The main function of mitral valve is to regulate the flow of blood from the upper left chamber into the lower left chamber. It is considered as the heart’s main pumping chamber. It allows the blood to flow in one direction and prevents the leakage backwards through the valve.

Mitral valve implantation is an open heart surgical procedure. In this procedure, the diseased mitral valve is replaced by a new valve. There can be two types of replacement valve. It can either be in the form of a mechanical valve which is made of plastic or metal or a bioprosthetic valve made from human or animal tissue.

Why it’s done

  • Mitral valve stenosis
  • It is the condition which occurs when the opening of the mitral valve is narrowed. The abnormal valve doesn’t open properly and blocks the blood flow into the main pumping chamber of the heart. Rheumatic fever is the main cause of mitral valve stenosis. It causes the flap to thicken or fuse.
  • Mitral valve regurgitation
  • It is the condition in which mitral valve does not close properly when the blood is pumped out of the heart. This allows the blood to flow backward in your heart. It is most commonly caused by mitral valve prolapse, damaged tissue cords, rheumatic fever, endocarditis, heart attack, cardiomyopathy, congenital heart defects etc.
  • Other causes of this condition include infection, calcification, inherited collagen disease. In calcification, calcium deposits build up around the ring around the mitral valve.

Procedure

  • You will have to shave off the hair at the location of the body where the procedure will take place. You will receive anesthesia which will make you unconscious during the procedure.
  • To maintain the flow of blood, you will be connected to a heart-lung bypass machine.
  • An incision will be made under the upper left side of the body or vertically through the sternum. To expose the mitral valve, an incision will be made in the left atrium.
  • The valve is then replaced by implanting either a biological or mechanical valve.
  • The left atrium is then closed and the patient is taken to Intensive Care Unit.
