I have done a lot of reseach on TVR as of late as I recently had my mitral valve repaired and was left with an increase in residual TR. Prior to MVR, my TR was "trace", given my surgeon absolutely no reason to repair it. However, my two month post-op echo indicated moderately-severe TR with moderate PH. I just spoke with my surgeon and he said this should subside by 6 months post-op, however, it may not. I guess I just have to wait and see? From my research, TR is common, especially with MVR. It was thought that IF you repaired the left-sided lesion (MV or AV), the TR would improve. THIS isn't necessarily the case. In fact, many centers/surgeons advocate for cocommitant repairs (fixing the TV at the same time as MV or AV) despite the level of regurgitation IF the TV annulous is 3.5 cm or greater as if there is dilitation, it's been found that TR will presist in 40% of patients. Late TR after MVR or AVR has a poor prognosis and this is why many surgeons are becoming much more agressive with this. My first question to your surgeon/cardiologist would be, "What is my TV annulous dialated to?" Again, if it's equal to or greater than 3.5cm many surgeons will repair it at the same time regardless of the level of regurgitation. Very interesting stuff. I urge you to go on line and type in "progression of TR after mitral valve repair." Again, there was no reason for my surgeon to repair my TV as the level of regurgitation was only trace and my TVA didn't meet the 3.5cm or greaqter criteria my surgeon uses. However, I find it interesting that it went from trace to moderately-severe post MVR. Again, this can improve, as it often does, but there really is no way of knowing for certain. Let me know if you need any information. I have a lot of articles from various medical journals on the subject as my brother is a physician and has access to them...many of these you have to pay for...which sucks and adds up. Good luck to you!
