My Dad had a life long heart murmur, they discovered it after he enlisted in 1941. In 1974 they told him it needed to be replaced, and they gave him a pig valve. They said he was too old for a mechanical one.
He had the surgery, recovered just fine, and lived another 30 years.
I think you’re gonna be just fine.🙂👍
When I found out about my heart murmur when I was 50 years old, the Cardiologist told me it was hereditary, and I was born with it, that floored me because I know of no one in my family that has the same condition, unless it came from my grandparents, which I didn’t really know, 2 of them had died before I was born and a 3rd died with I was 3 years old and if they had the same condition, it wasn’t looked for that long ago.
