I have undergone mitral valve repair, and my surgeon didn't know if he could repair the valve until he had my heart open. I had to decide what I wanted him to do is the valve could not be repaired. I chose a mechanical valve, but I was luck and he was able to repair may valve. The surgery was almost 5 years ago, and the valve is still working fine, I had an echocardiogram just a couple of months ago and the valve, all valves, checked out as good.
To your first question, I do not know if a valve can be too damaged for a replacement to work but I doubt it. I say this because I believe a valve replacem, mechanical or organic is a complete replacemnet. I think valves are completely reactive, that is they open and close according to the direction of the flow/pressure. Thus if the valve opening is filled with a replacement valve, it would work.
I am not a doctor, and I have no experience beyond what I have stated.
Hello, I am guessing that once the infection is cleared up, your doctor may revisit the idea of a replacement valve. My experience has been that physicians will not place any kind of a device (like a heart valve) when there is an existing infection because the risk of that device then becoming infected is high. If a new heart valve were to become infected, its much more difficult to clear up an infection.
What kind of infection were you referring to?
