Echocardiography for transcatheter aortic valve implantation.

Transcatheter aortic valve implantation (TAVI) is a new technology that treats severe aortic stenosis. The technology has specific and mandatory technical requirements that must be met to allow safe and successful procedures. The echocardiographic method for diagnosis of aortic stenosis, anatomical case selection, procedural guidance and management of complications is discussed in this context. The role of the imaging specialist is defined within the TAVI team aiming to provide good outcomes for this high risk cohort of patients.
