TAVR is percutaneous deployment of bioprosthetic valve in aortic root
Endovascular access point for delivery of valve is commonly femoral artery; however, other options include left ventricular transapical approach
It is treatment of choice for patients with aortic stenosis at high or intermediate surgical risk and as alternative for those at low surgical risk
