I have a mechanical valve and it has a leak around the outside of it. The Dr wants to "Plug" The leak in the valve. This is at UAB Birmingham. My cardiologist at the Cleveland Clinic did not eat to do this at this time. Im kinda confused as to what to do. Do it or don't do it. UAB said it would extend the life of the valve and make me less tired but Cleveland didn't think it was necessary at this time. Has anyone else had this done? Thanks.
