Imaging to select and guide transcatheter aortic valve implantation.
Transcatheter aortic valve implantation (TAVI) is indicated for patients with severe aortic stenosis and high or prohibitive surgical risk. Patients' selection requires clinical and anatomical selection criteria, being the later determined by multimodality imaging evaluation. Echocardiography, multislice computed tomography (MSCT), angiography, and cardiovascular magnetic resonance (CMR) are the methods available to determine the anatomical suitability for the procedure. Imaging assists in the selection of bioprosthesis type, prosthetic sizing and in the decision of the best vascular access. In this review, we present our critical appraisal on the use of imaging to best patients' selection and procedure guidance in TAVI.
