Key result
Computed tomography is the primary and most informative diagnostic method for comprehensive pre-operative planning of transcatheter aortic valve implantation.
Computed tomography is the cornerstone imaging modality for TAVI planning, and adherence to standardized scanning and measurement protocols is essential for optimal patient selection and procedural success.
Supports standardized pre-TAVI imaging protocols; leaves open need for updated consensus with post-2020 evidence.
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.

Bulanova et al. (2021) conducted a review in Aortic valve stenosis. Imaging modalities (Computed tomography, MRI, Echocardiography) was evaluated. Computed tomography is the primary and most informative diagnostic method for comprehensive pre-operative planning of transcatheter aortic valve implantation.
