Hey Neil, many congratulations on your 8 year check-
Your reviews were very useful and informative when I went through my surgery in 2012, I also went for Porcine
Would it be ok to ask how hold you were at time of surgery, I was nearly 53, also do you know which model of valve you received.
My surgery was carried out at Derriford in the UK.
Once again congratulations from a fellow Brit!!!!
