4 Aortic Surgeries any one else ?

I have had four open heart surgeries, first I was 11 in 1973 . Only thing they could do is was a valve ectomy slices in the valve . 1978 had an aortic pigs valve installed . 1984 had a St Jude’s aortic installed . Took to blood thinners very well. In 2023 I had my 4th aortic Bovine valve installed. My heart was too damaged to receive another St Jude’s mechanical valve . After my 4th surgery I no longer have the energy and or stamina like I had before. I am not complaining because I’m as healthy as can be in my situation. Thank God for family. What I am asking are there anyone else out there that has ha the same or more. Just curious. I will be 64 this year
