Detailed explanation-1: -Transcatheter aortic valve replacement (TAVR) substantially improves survival and quality of life (QOL) in the majority of patients with severe aortic stenosis. Nonetheless, a substantial minority of patients continue to have poor QOL or die soon after undergoing TAVR.
Detailed explanation-2: -TAVR is approved for extreme-risk, high-risk, and intermediate-risk patients with symptomatic severe aortic stenosis.
Detailed explanation-3: -One reason TAVR is currently restricted to patients at higher risk is that it’s a pretty new procedure, so we don’t have established data for how it compares over the long term to traditional surgery. One of the questions up in the air surrounds the durability of the valves used in TAVR.
Detailed explanation-4: -The low-risk patient population is the final surgical risk category to be approved for TAVR, a minimally invasive alternative to open-heart surgical valve replacement (SAVR), and includes patients who may be younger and more active than higher-risk patients.
