@aSurgery is an option. I am 92 and although Northwestern Memorial in Chicago has turned me down without an option, I contacted Cleveland Clinic and another cardiac surgeon here and both will operate when the time comes. C.C. has even told me the type of surgery - "partial open!" I am in good health although about 20# overweight, walk a mile in the pool 3 days a week and maintain low b/p. Keep the faith!
