Greetings . My AVR surgery was a little over three years ago with a mechanical valve implanted. As such, I don't have any particular questions or concerns at the moment. Although I did not discover this forum at a time when it might have allayed some pre-surgery anxiety or addressed post-surgery recovery concerns, nevertheless I have found the site contents useful in gaining insight on certain perspectives as it pertains to anti-coagulation therapy, INR target management and self-testing, bridging, recollections of the valve-replacement experience, and other matters that have piqued my interest. After perusing the site for quite a while, I finally decided to switch from a lurker to become a participating member of the community forum. I extend my appreciation to those sharing their experiences and information sources on various topics.
