Hello everyone. It's been a long while since I've been on the forum. In February 2021 I celebrated a 5 year anniversary with my St. Jude mechanical heart valve. Through hundreds of Warfarin tablets later and at home INR testing, I still don't regret my choice for a mechanical valve. For those of you who will soon join this distinguished club and are anxious about making a "wrong" decision on a tissue or mechanical valve, just be sure to learn all you can from those who have gone down this path (patients and surgeons) and choose the valve that you believe is right for YOUR circumstances. My heart was set (pun intended) on a tissue valve I but utlimately chose a mechanical. I was in my mid 40's and a mechanical valve made the most sense for me. Thanks everyone and God bless.
