Just curious because it seems to me that the majority of the threads I have read on valvereplacement.org, ARV candidates have chosen ON-X. Even though I really value the advice and experience of patients, I want to be as open as I possibly can to making the right informed choice for me as I possibly can. BTW, I posted in this forum instead of valve selection forum because I'm assuming most of you have already decided versus those that are still considering their options.
