Can you define stenosis of a heart valve?

Valve. The valve opens to allow flow out of the heart to the body. If it doesn't open properly we call this stenosis. It has to close properly to keep blood flowing in a forward direction. If it doesn't we call this insufficiency. Either or both abnormalities can exist in the valve.

Overall good. It is impossible to be precise about your individual situation without knowing the details of your medical situation. As a general rule if the heart function is normal ( as with an ejection fraction of 55% it sounds like it probably is) this is a good sign. Read more...
Unknown. There is no real answer to this, impossible to predict. It is a really important question. I empower you to have open discussions with your mds. Better question how long will my valve last? What is the risk of my next operation? Read more...

How do heart valve replacements work?

Remove/Replace. The heart is stopped. The patient is placed on bypass which pumps blood and breathes for the patient while the heart and lungs are not being used. The old valve is removed and a new valve is stitched in place. This can be either a "tissue valve" from a pig or cow, or a mechanical valve which is completely artificial. Read more...
Valve replacement. The surgery replaces the valve with either a mechanical or animal tissue valve. This is done on a heart lung machine. The valve takes the place of the damaged valve and the patient lives their life with a new disease 'artificial valve' with its own set of problems. The obstruction or valve leak of the diseased valve is corrected by the artificial valve. Sometimes blood thinners are needed. Read more...

How is a heart valve surgically repaired?

Depeds which valve. Repair most commonly is done on mitral valve, especially when mitral prolapse is present. The excess, "floppy" tissue causing the valve to prolapse is excised to make leaflets more taught. Sometimes an artificial ring is inserted around the base of the leaflets to cinch the whole apparatus together, if it has become dilated, preventing leaflets from closing up against each other.
