He also has Ehlers Danlos syndrome, connective tissue disorder. He was told if it was not for his pacemaker and difibulator he would not be alive! Trust me we are all scared to death. What I need to know is he a candidate for such a serious surgery considering he has Ehlers Danlos Syndrome. Please let me know what you know.
