Brenda,
At the age of 55 and after 17 years of living with porcine aortic valve, the yearly echo test uncovered a leak in the valve. Three weeks after the echo test I had the valve replaced with a new Hancock II porcine valve.
I didn?t wait to be symptomatic because of the valve failure (small tear in the base of one of the leaflets), being in good physical condition helped me recover from the surgery in record time, I was climbing steps after two day and return to work after 4 weeks.
My surgery was done last November, I feel just fine and back to my normal life style. I hope that the new valve will last at least 15 years and if at that time I have the same experience as I had this year, I wont heisted to do it again.
