The more surgeries the more scar tissue in there. Also, some of us have had endocarditis after 2 surgeries requiring a 3rd we weren’t expecting. Be open for another surgery or 2 down the road. You never know. Taking warfarin is just another pill and a self test once a week.
Plus, I got chronic a-fib after 3rd surgery so i would’ve ended up on warfarin. I choose not to call it poison because that’s pretty negative.
