Multimodality imaging in transcatheter aortic valve implantation: key steps to assess procedural feasibility.
Transcatheter aortic valve implantation (TAVI) has been an important breakthrough in the treatment of patients with symptomatic, severe aortic stenosis and contraindications for surgical aortic valve replacement. Accurate aortic root measurements and evaluation of spatial relationships with the coronary ostia are crucial in pre-operative TAVI assessment. In addition, characterisation of the peripheral artery anatomy and aorta is an important key step in the procedural feasibility evaluation. The present review article provides a practical approach, based on multimodality imaging, to select candidates for TAVI and to evaluate the procedural feasibility.
