The role of TTE in assessment of the patient before and following TAVI for AS

Transcatheter aortic valve implantation is now accepted as a standard mode of treatment for an increasingly large population of patients with severe aortic stenosis. With the availability of this technique, echocardiographers need to be familiar with the imaging characteristics that can help to identify which patients are best suited to conventional surgery or transcatheter aortic valve implantation, and what parameters need to be measured. This review highlights the major features that should be assessed during transthoracic echocardiography before presentation of the patient to the 'Heart Team'. In addition, this review summarises the aspects to be considered on echocardiography during follow-up assessment after successful implantation of a transcatheter aortic valve.
