Transcatheter aortic valve replacement (TAVR) is a minimally invasive procedure to replace the aortic valve in patients with severe aortic stenosis. The aortic valve is located between the left lower heart chamber (left ventricle) and the body's main artery (aorta). If the valve doesn't open correctly, blood flow from the heart to the body is impaired leading to congestive heart failure, chest pain, dizziness, passing out, and even death. 

TAVR may be an option for people who are at risk of complications from surgical aortic valve replacement (open-heart surgery). The decision to treat aortic stenosis with TAVR is made after a discussion with a team of structural heart specialists and heart surgery specialists, who work together to determine the best treatment option for you
