What are the risks for an 80 yearold with chf having an aortic valve replacement?

Variable: Much of the risk lies on underlying medical conditions and if the CHF is due to the aortic valve dysfunction. If the person is otherwise healthy and the CHF is thought primarily due to the valve problem, the bigger risks of surgery (bleeding, stroke, infection, anesthesia) would relate primarily to the patient age. We do bypass surgery and valve surgery on 80 yo patients quite routinely.

Depends: 80 is not the risk. Other systemic issues? Smoker, anemic, hypertensive obese, dementia, strokes if the valve is the cause of the heart failure, the patient will benefit! major morbidity/mortality in 30 days about 5% or so depending.

Chf: The other major factor for peri operative risk is the heart failure. The more severe the heart failure the higher the risk.

STS risk calculator: You can estimate the risk with the sts risk calculator. Search "sts risk calculator" on your favorite search engine. Based on many factors; age, comorbodities, renal function, ect... It will estimate the risk of having a avr.
