Key result
Echocardiography guides patient selection, sizing, procedure, and follow-up in TAVR.
Why the study?
Echocardiographic imaging is critical for patient selection, valve sizing, procedural guidance, and follow-up in transcatheter aortic valve replacement for degenerative aortic valve stenosis.
This review highlights the critical role of transthoracic echocardiography in all stages of TAVR, from patient selection to post-implant follow-up.
Echocardiography guides TAVR workflows; leaves open standardization of protocols and prospective outcome validation.
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.
