What Is The Prognosis After A Bentall Procedure In An Elderly Patient?

My brother age 74has endured the bentall procedure barely escaping dying......he is in icu now for 3 weeks having suffered various setbacks. His vocal chord was damaged by a trach, he s been lying still the whole time, is just now staring pt, has a nasal feeding tube, can t swallow n is incoherent and not making sense when he tries to speak n we can barely hear him as the vocal chord doesn t close.....what does his future look like. He s a lawyer n walked golf course 2xs a week, one week before he wound up with emergency cardiac surgery.....was opened up 3 times for bleeding n then an aortic stitch had to be repaired...been thru the mill!
