Nice to meet someone else with a unicuspid valve (well, I used to have one). Your surgery is a day before my AVR one year anniversary. My AVA was .9 at time of surgery. My results from stress echo made my surgeon opt for surgery (even though I was successfully able to run at top speed at the top incline setting with 20 pounds of wires on me- oh well). My dad got his SJM in 50’s. He’s had it over 15 years now. Valve looks great and no complications. I got an On-X. I keep INR above 2.5. He does too. Both options are great. Wishing you the best. You’ve got this. BTW- Just saw that you had first procedure at Cleveland Clinic. They are wonderful. That is where mine was replaced. Had a mini-thoracotomy.
