Imaging modalities in the planning of transcatheter aortic valve implantation (standardization of scanning, measurements and reporting protocols)

This review describes the state of the art on the role of various imaging modalities in pre-operative preparation to transcatheter implantation of biological aortic valve prosthesis, based on the literature data published from 2012 to 2020. One of the key source documents is the consensus of the European Society of Cardiovascular Radiology (ESCR) from 2019, providing the standardized protocols for scanning, measurements and description of the abnormalities identified. The final decision on the procedure of transcatheter aortic valve implantation should be based on the combination of all available diagnostic methods, clinical data and results of imaging by different modalities. Given the most comprehensive information content, the main diagnostic method is computed tomography. The radiologist and the multidisciplinary team should form a single entity, combining clinical and technical knowledge, discussing all the images and conclusions with other team members.
