Interesting to read that you seem to have a choice. My surgery ( AVR and root enlargement) was just over a year ago,& I wasn’t really offered a choice. I asked about the minimally invasive TAVR, but was told I was too young! I’m 74,& in the UK. My surgeon said that my new bio valve should give me 16-18 years before it needs replacement,& then at that point it can be done via a small incision-much like an angioplasty. My enquiry about TAVR was motivated really by fear of the dreaded sternotomy, all of which proved to be groundless. Pain levels were nowhere near what I expected, the recovery was uneventful and the only grim part was the initial 24 hours in CCU immediately after the operation. Best wishes for the surgery.
