How risky in a heart surgery that involves replacing a heart valve, and fixing two aneurysm?
We found out that some one I know needs to have an open heart surgery because she was born with only two heart valves. On top of that they discovered two aneurysm in her heart and need to operate on her within a week. I know that all surgery is risky, but if any one can shed some light on this situation and possibly show me some statistics, it would be much appreciated.
