Neda: I had the Bentall precedure done on May 3 of this year. This is what the surgeon said in his post-op report--"underwent modified Bentall aortic root replacement with a Number 23 St. Jude Valve conduit and replacement of ascending aorta with a number 28 Hemashield graft using right axillary cannulation". (The surgery was about 6 hours--on bypass for 3 1/2-4 hrs.) This does sound like what you will have done. I was 58 (just had a birthday and am now 59). I had no problems in surgery. The only problems I had after surgery was very bad upper back paid (heat packs helped) and some A fib. Everyone said the A fib was normal and I did convert a couple of days after I went home. I was in SICU less than 24 hours and went home from the hospital on the 6th day (I could have gone home on the 5th day but the A fib had me concerned.) I am doing cardiac rehab now and feel great! I drove 4 1/2 hours this past weekend to babysit the grandkids. Let me know if you think I can answer any questions for you or help with any of your concerns.
