Who is a candidate for transcatheter aortic valve replacement?

Because transcatheter aortic valve replacement is a relatively new technique, and because the very long-term outcomes of this form of valve replacement are somewhat unknown, surgical aortic valve replacement remains the standard of care for patients at low risk for surgery based on things like age and other medical conditions the patient might have. Patients at intermediate or high risk for surgery are candidates for transcatheter aortic valve replacement.
