Thanks to everyone for all the good words. Someone asked about the valve, so I will share a little more info. I am 63 yrs old and have no health problems other than this. Have normal blood and normal blood pressure even though my dietary and exercise habits are horrible. I am probably 30 lbs overweight and smoked for 45 yrs. I am having the On-x mechanical valve. The surgery will be performed by Dr Marc Gerdisch at the St Francis Heart Valve Center in Indianapolis. I have had time to do a lot of research on my problem, and chose the surgeon and hospital. The credentials of the surgeon and the hospital are both top drawer. Still, this is a very serious surgery with a lot of things that can go wrong. Accordingly, I have a lot of anxiety. I hope that I will be able to resume a healthy active life where I will take the time to exercise, eat properly, and abandon the tobacco. Again, appreciate all the kind thoughts and I hope to make future post operative posts telling everyone how great I feel. Regards, Bud
