I'm sorry to hear your bad news. Don't give up. That is one doc's opinion and suggestion. Maybe you can get her in to see someone else and see what they have to say. They can do things to prep her for blood loss BEFORE surgery. They have a nice hormonal drug called epogen that causes the body to build blood at a much faster rate. This will sometimes eliminate or greatly reduce the chance that they will give her blood transfusions. There are also other blood conserving techniques that they can utilisize. It seems that her heart condition is the big limiting factor here. You need the BEST in both heart and spine care for her. I hope you can figure things out. My well wishes are with you both. Take care.
