	Eight years prior to his demise, this 48-year-old black male had a dissecting aortic aneurysm. The first portion of the aortic arch was dilated ~~with an~~ associated aortic valve insufficiency. The defect was repaired and a mechanical prosthetic valve was implanted. One year prior to his terminal admission, the patient experienced a catastrophic cerebrovascular accident (CVA) with left hemiparesis and obtundation. The patient experienced severe neurologic sequelae from this CVA and was eventually transferred to a nursing home where he was bedbound and required an indwelling urinary catheter. ~~The~~ patient developed a urinary tract infection and was transferred to the hospital. The patient's condition deteriorated ~~and he died 6 weeks after admission~~ with a urinary tract infection and pneumonia.
