title: How to assess aortic annular size before transcatheter aortic valve implantation (TAVI): the role of echocardiography compared with other imaging modalities.
abstract: After reading this article, the reader should be able to: Recognise the complex 3 dimensional anatomy of the aortic annulus. Select appropriate cardiac imaging modalities for measurement of aortic annulus size and distinguish the different measurements which may be made. Describe the advantages & limitations of different imaging modalities with reference to clinical outcomes and complications.
