Gisele-
I don't know how you feel about having that valve replaced.
If you ever come to the place in your mind when you have made your own decision about the direction you want to go in, and if it is to have the surgery, then why not press the issue with your cardiologist? It is really horrible to be living in such fear, worrying about getting a clot on your valve or having another neurological problem.
I know that when things are complicated, they like to wait until the risk of having surgery is less than the risk of waiting. Joe was in this kind of position when he had his mitral leak. He couldn't do anything at all, but sit on the sofa, and he wasn't even comfortable doing that. He could hardly walk around. His cardiologist found the decision very difficult to make because this would be Joe's third valve surgery and it would be risky for him. Joe finally made the decision for himself and decided to push hard to have it done. He really laid it on the line for the cardiologist and told him that he absolutely wanted to have it done, no matter what, that what he was doing wasn't living, and he wanted the chance to have a better life.
I believe that discussion took some of the burden off the cardiologist. But even at that, Joe still had to push hard to make it happen.
It was the right thing to do, and his mitral was repaired and although he has other cardiology and pulmonary problems, his valves are both fine.
I do believe the patient can have some influence in the decision making, if that is the direction you want to go in.
I'm not trying to influence you one way or the other, only giving you some food for thought.
Hugs,
