Erroneous Measurement of the Aortic Annular Diameter Using 2-Dimensional Echocardiography Resulting in Inappropriate CoreValve Size Selection: A Retrospective Comparison With Multislice Computed Tomography

Study Questions:

Does annular sizing using transesophageal echocardiography (TEE) and computed tomography (CT) result in differences in valve size selection and paravalvular aortic regurgitation (PAR) in patients treated with transcatheter aortic valve replacement (TAVR)?
