Hi Mary, I had quad bypass 3/2000. Mine were 95% blocked and I had a heart attack. The surgical going in and coming out are exactly the same as the going in and out for valve surgery. I have the same scar. Recovery time and activity are the same. The one difference is that you will have some new meds, probably and will have to learn to read labels when you grocery shop. Your cholesterol will have to be watched carefully. In hospital they will probably give you lots of information to teach you how. You will need to begin exercises. You may be put on a statin drug to lower your cholesterol. Listen to your muscles, especially the leg muscles and if you have weakness or pain, you will want to notify your doctor and ask for a change to another as, in some people, statins can do much damage (it did that to me). I finally refused to take any more statins so my dr put me on zetia and it is doing a good job. Statins don't harm most people. If you are on a cholesterol lowering drug you will have to get a lipids blood test every six months to be sure your liver and cholesterol (a few other things too) are ok and within proper limits.. I expect the dr will bypass the ones he finds that are blocked while he works on your valve. Some valvers in VR have had both done at the same time and might stop here to give their experience.
