    Aortic Stenosis (AS) is by far the most prevalent form of VHD in the elderly. The contemporary etiologies of AS are due to degenerative mechanisms rather than rheumatic diseases, especially in the western world. Transcatheter aortic valve implantation (TAVI) has evolved dramatically as an alternative treatment to surgical aortic valve replacement (SAVR) in patients with severe AS. The fast development of TAVI can be linked to the rising competence of interventionists and the improvements in technology and imaging techniques. In order for the TAVI procedure to be successful, multiple imaging modalities (TTE/TEE, MDCT, etc.) must be utilized. These imaging modalities are utilized for a variety of purposes, including but not limited to guiding pre and post-procedural evaluation and planning, intra-procedural imaging, and follow up.
