Multimodality imaging remains essential to determine anatomical suitability, bioprosthesis sizing, and vascular access in TAVI.
Multimodality imaging is crucial for patient selection, bioprosthesis sizing, and procedural guidance in transcatheter aortic valve implantation.
Supports multimodality imaging in TAVI planning; leaves open optimal modality combinations in prospective studies.
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.

Zamorano et al. (2014) conducted a review in Severe aortic stenosis. Multimodality imaging (Echocardiography, MSCT, angiography, CMR) was evaluated. Multimodality imaging, including echocardiography, MSCT, angiography, and CMR, is essential for determining anatomical suitability, bioprosthesis sizing, and vascular access in TAVI.
