This is slightly off track, but I thought might be worth mentioning. I was diagnosed with moderate to severe sleep apnea several years prior to my surgery. I gave CPAP a try a few nights, then gave up, thinking I couldn't handle the daily hassle, and still not too convinced by the local sleep center how necessary it really was (I wasn't symptomatic). I also later saw a specialist who normally would have recommended corrective jaw surgery, but when he found out I had BAV, would not even think about it, due to endocarditis risk.
Anyway, I basically just ignored it from then on. But when I found out I needed heart surgery, in only a few weeks, a cardiologist and pulmonologist both were firm in the belief that I needed to control the sleep apnea condition prior to the surgery. Intermittent low oxygen levels and heightened stroke risk during sleep may not be that big a deal in the normal life of a young person, but they become a lot more important concerns when facing heart surgery, short term recovery, then life in general with a prosthetic valve. So, I started back on CPAP a week before my surgery, used it in the hospital, and every night since. Nothing like a little extra motivation to take care of things in a timely manner.
