Transcatheter aortic valve replacement ( TAVR ) has been a revolutionary technique in the treatment of degenerative aortic valve stenosis. Selection of appropriate patients and appropriate valve size is crucial for improved patient outcome. Echocardiographic imaging is a critical component for patient selection and plays an important role in the selection of valve size, procedural guidance, and patient follow‐up. This review discusses role of echocardiography in patient selection, device implantation, and postimplant follow‐up for the first‐generation CoreValve as used in pivotal trial. Same TTE imaging principles apply to the second‐ and third‐generation self‐expandable valves as well as the balloon‐expandable valves. Multiple case examples are used to illustrate imaging principles pre‐ and post‐ TAVR . In addition, case examples to demonstrate complications post‐ TAVR are shown.
