Good luck! Hope all goes great for you! I had just aortic valvle replaced with tissue one 2 weeks ago tomorrow. Onlly complication was I developed a-Fib; was in it 75% of the time a week ago; I think it is getting better and down to about 60% of the time now. Pain is mostly my back! Little pain in chest. 5 days in hospital. I would think replacing 1 or replacing 3 would be no different other than time in surgery! Once closed back up, all the stuff to hurt will be the same as a single valve replacement job I would think. They said I was in surgery 4.5-6.5 hours, depending on who you ask (crazy, I think some think in recovery afterwards counts). I would guess a valve replacement itself is about 30 minutes of the total surgery time, so for you just another hour. Have you seen the valve replacement? Pretty simple looking; cutout the old, stick this in then bend over the metal crimps to hold in place. I am sure it is much more complex, but I bet it is still just 30 m inutes each, so your surgery should be little different than the rest of us with 1 vale replaced. Hope my guessing helps you feel better about it!
