Transcatheter aortic valve implantation (TAVI)
Transcatheter aortic valve implantation (TAVI) is a minimally invasive heart procedure to replace a thickened aortic valve that can't fully open (aortic valve 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 reduced. TAVI can help restore blood flow and reduce the signs and symptoms of aortic valve stenosis — such as chest pain, shortness of breath, fainting and fatigue. TAVI 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 TAVI is made after a discussion with a team of heart and heart surgery specialists, who work together to determine the best treatment option for you. Transcatheter aortic valve replacement may also be called transcatheter aortic valve replacement (TAVR).
