Multimodal Imaging Evaluation of Aortic Stenosis.

Transthoracic echocardiography (TTE) plays the primary role in the assessment of patients with aortic stenosis (AS). Alternative imaging modalities are important for the confirmation of AS severity in patients with discordant AS or inadequate assessment by TTE. Multimodality imaging can inform prognosis in patients with AS. In this article, we discuss the role of multimodality imaging for accurate diagnosis of AS severity and assessment of prognosis to inform patient management. We provide an overview of the use of computed tomography for procedural planning for transcatheter aortic valve replacement.
