Multi-modality imaging of the aortic valve in the era of transcatheter aortic valve replacement: a guide for patient selection, valve selection, and valve delivery.
Aortic stenosis is a common condition traditionally treated surgically. Transcatheter aortic valve replacement (TAVR) is an exciting and new method allowing treatment of high risk and inoperable patients. Multimodality imaging is extremely important in the preprocedural evaluation, the performance of the procedure, and the post-procedural assessment and includes transthoracic echocardiography, transesophageal echocardiography, conventional angiography, multi-detector computed tomography, and cardiac magnetic resonance. This paper will review the role of various imaging modalities during the phases of the TAVR procedure with an emphasis on the advantages and limitations of each approach.
