Hi jjwb-
Welcome to the site. It's a terrific place where everyone knows so much about valve surgeries and way beyond. Smart group of people and very nice as well. We all really care.
My husband has had 3 valve surgeries, 2 lung surgeries, has a pacemaker and has had a lot of other very serious things, some of which were worse than his valve surgeries.
He just had his last surgery, a repair on the mitral which was leaking, in July of 2001. That one was done with the Heart Port method through the side and was a much better deal, recovery-wise. Joe is 71 years old, and he's still chugging along. His valves are mechanical.
So your dad will be fine. It'll be a little longer recovery than the "young-uns", but he'll get there. It sure beats the alternative.
Please feel free to come here often and ask us any questions you want. You're bound to get a lot of answers.
And let us know the date of his surgery because we love to follow our family though the process. We'll put him on the calendar.
Nice to meet you.
