Hi Cindy-
And welcome to this great site. It's a wonderful place to come for support, friendship and education on all the subjects surrounding valve replacement. There is a ton of information in all the threads here.
Valve choice is a tough decision, and the more you can learn about the different valves, the better. An informed patient is a good thing.
My husband has 2 mechanical valves, and has been on Coumadin for 25 years. He has never had a bleeding incident that can be attributed to Coumadin. His Coumadin is very well managed by his doctors.
Unfortunately, Coumadin has gotten a very bad rap that it doesn't deserve. I believe that the bad rumors are generated by ill-informed people who know nothing about the drug. And most of the bleeding incidents that everyone hears about are the result of either poor management by the doctor, or poor compliance by the patient, not taking the right dose or not testing the patient often enough.
You are young and will probably opt for a tissue valve. But later on when you have that valve replaced, you might want to go with a mechanical valve, and I just wanted you to know that Coumadin is not the big baddie that lots of people think.
It is truly the least of my husband's medical problems.
Best wishes to you.
