Im new here today....but having AVR surgery in 8 days.....im very fortunate to have an excellent surgeon....He recommends me having a St Jude valve since i am only 55 and could need one or more resurgeries if i live as long as my parents and grandparents...Ive been reading for days and days everything i can find of others experiences to help me make my final decision on the St Judes or an Edwards Pericardial Valve. I think I could handle one more pill a day and would be diligent to keep tabs on my INR #s. My other concern, altho it may seem trivial, is that i am one of those people who needs quiet to be able to sleep. If those of you who have gotten a mechanical valve could tell me how you are affected by any of the possible sounds your mechanical valves make when trying to fall asleep, i would REALLY appreciate it....thanks a lot...ill be monitoring this site hourly if not more frequent till my surgery on the 9th of june..2010.....thanks all and God bless......PS....I am Address removed for members safety .....id love any info
