Objective Assessment of aortic annulus dimensions prior to transcatheter aortic valve
implantation (TAVI) is crucial for accurate prosthesis sizing in order to avoid prosthesis …

Objective: We sought to determine the level of agreement and the reproducibility of trans‐
thoracic echocardiography (TTE), contrast aortography (CA) and multislice computed …

Aims To evaluate the effects of applying current sizing guidelines to different multislice
computer tomography (MSCT) aortic annulus measurements on Corevalve (CRS) size …

Background Annular dimensions, including cross-sectional area, perimeter and
subsequently derived diameters, are subject to dynamic changes throughout the cardiac …

Transcatheter aortic valve replacement is a new method to treat patients with symptomatic,
severe aortic stenosis who are at high surgical risk. Short-and midterm results have been …

Background In transcatheter aortic valve replacement, prosthesis oversizing is essential to
prevent paravalvular regurgitation. However, the estimated extent of oversizing strongly …

Objectives: This study compared cross-sectional three-dimensional (3D) transesophageal
echocardiography (TEE) to two-dimensional (2D) TEE as methods for predicting aortic …

Objectives: In the present study, the anatomy of the aortic root was assessed noninvasively
with multislice computed tomography (MSCT). Background: Transcatheter aortic valve …

OBJECTIVES The precise sizing of the aortic annulus is crucial in order to select the most
appropriate valve size for transcatheter aortic valve implantation (TAVI). Owing to the closed …

Objectives: The purpose of this study was to assess deformation dynamics and in vivo
mechanical properties of the aortic annulus throughout the cardiac cycle. Background …
