Hello Elina1 and Betty,
TAVR is not used for Bicuspid Valve replacement. It is designed to replace a standard Tricuspid Valve only. I went thru the Aortic Valve replacement surgery on early 2018, and they would not do a TAVR on the Bicuspid Valve. My requesting a TAVR wan't going to happen. A tissue valve is probably what they will want to use. You should discuss the Replacement Valve options very carefully with the surgeon. For folks older than 70 they usually do a Tissue Valve. I was 52 so they opted for a Man Made Valve. If a Man Made Valve is what they will use, ask for the On-X Aortic valve. Has the lowest blood thinner approval by the US Government. Less meds.

For me Valve Replacement Surgery was a breeze compared to the 2 prior Bi-pass and Aneurysm Surgeries. Those were many weeks in the hospital. Cut openen from the side. Don't join that club. I understand there is an age difference, but his body will tolerate it very well. His recovery will just be longer than someone younger. Tell him to keep his chin up! An you keep his spirits up and yours too!! Keep us all informed on the outcome.

All the best!
