I looked to see if this is listed somewhere but didn't find it (its from 09) but there is a pretty good PDF put together by the "The Society of Thoracic Surgeons to help answer some questions that patients and their families often ask after heart surgery or, sometimes, before their surgery so that they are better prepared for recovery. Remember: If your doctor's instructions differ in any way from those listed here, always follow your own doctor's specific instructions"
I thought it was pretty good and mentions alot of things people ask about that doctors don't think to mention, like the lump /bump at the top of the incision (yes it is normal) your taste may be off, trouble sleeping ect
