Hi Jack. I think the person you are referring to is a lady from England. I've seen her record in Guinness and, as I remember, her surgery was about 1-l/2 years after mine. I looked into trying for this record and had Guinness send me info for applying. I was not able to satisfy their documentation requirements after all these years so I didn't pursue it.......anyway, we already have a Guinness record holder in the family. My grandson-in-law holds the Guinness record for "fastest auto driven in reverse". I think it was a little over 100 mph . His name is Darren Manning, from England, who was an "open wheel" racing car driver before he married my grandaughter.
Here's what they say now.
"The longest surviving artificial heart-valve transplant patient is Doris Clare (b. 20 Sep 1926, UK), who received an aortic valve replacement on 30 April 1969, in Woolwich, London, UK, and as of 15 July 2013 has had it for 44 years, 76 days. "
Yep, that's the same lady. Her surgery was 4/69....mine was 8/67. If she is still around she is 92.....and that IS a big deal. These long term valve stories should comfort those of you with mechanical valves.
