Hi Mark,
My valve was aortic, so maybe some mitral valve people will have more insights to offer you....
If you are truly close to surgery time, I would want confirmation from the cardio about the timing - can it wait, and why or why not. I would make sure that you've had tests at least within the last couple months - definitely an echo. See if you might need a TEE (transesophegeal echo) to get a real good picture of your valve. Ask what your numbers are - your ejection fraction (a measure of the output of blood from your heart) (diminished?), size of your ventricles (enlarged?). Talk to him about your symptoms, if any. From my experience, it seemed that these three items (EF, ventricle size, and symptoms) were main factors in determining whether or not surgery was needed. Ask if you can take any drugs to help prolong the need for surgery, or to help ease the strain on your heart, if it's looking that you could wait a while. I would also ask him what valve he would recommend - mechanical, tissue (human, bovine, porcine) - and WHY. Talk about risks and benefits of each valve - their longevity, drugs that you would need to be on, risks of repeat surgeries - as related to YOU in your current age, lifestyle (sports etc), current health status, etc.
If it's looking like the time is near, ask what surgeon would he recommend, does he do a lot of mitral valves (as opposed to aortics), does the surgeon do REPAIRS. From what I hear from the mitral folks, they have a better chance for repair than the aortics. And, if you can find a surgeon who does repairs (not all of them do), a repair (from what I am told) would be preferable over a replacement. I would insist that your cardio set you up for a consult with the surgeon, and discuss all this with him.
Ask the surgeon:
* what your possibilities might be for a repair
* how long such a repair might be expected to last
* what valve he would recommend if a replacement was necessary - mechanical, homograft, porcine, bovine
* time on the bypass pump
* options: full sternectomy, or minimally invasive procedure?
* how many does he do a year of each
* is the time is NOW or what?
If you're not convinced or satisfied with the answers you get (or don't get), move on and get a second opinion. You only get one go-around for this. You are the one who has to get up on the table, you are the one who has to live with your choices. If they recommend a particular valve, contact the valve manufacturer and get some literature, and read up. Do the same with Coumadin. Get on the board here and read up and ask questions. Unlike Gary, I found I had most of my questions before the surgery. That was almost the hardest part - doing the research, following my leads, pushing docs to get answers, and listening to myself to learn what risks I was willing to accept and what aspects of my life I was not willing to give up. Once I was settled in my mind and sure of my plan, the rest was go with the flow (relatively speaking!!!!!).
Best wishes, I hope this helps. Let us know how your visit goes.
