My 89-year-old French mother-in-law moved in with us about three years ago. Because she has aortic stenosis/ congestive heart failure, the cardiologist is recommending that she have transcatheter aortic valve replacement surgery (TAVR). He mentioned that they would have to use general anesthesia. She is legally blind and very hard of hearing; besides heart issues she doesn't have major health problems such as diabetes or kidney. She is a smoker though. My big concern is that MIL has moderate dementia and I fear that the procedure could make things worse on this front. As I mentioned in previous posts, she does not qualify for Medicare/Medicaid and we would have to pay for skilled nursing care if she needs it. It's not open heart, but it's still a delicate surgery with associated risks such as stroke and requiring a pacemaker. Do any of you have thoughts or experiences with surgery on elderly folks with dementia?
