This is a little late, however, I wish your BIL the best. I had open heart surgery when I was 17 and in high school, in 1960. Still going strong. WIll say prayers for him. Now days it is easier they say then in the 60's My Dr. at Mayo Clinic in ROchester, MN said 6 months after I had surg. and was there for a ck up, that I had survived "Pioneer Surgery" and to keep doing well.
