Background There are limitations of using 2D imaging to accurately size the aortic annulus.
This article highlights the limitations of 2D technology and proposes a new 3D TEE method …

Background With the increasing use of transcatheter aortic valve replacement (TAVR) in
patients with aortic stenosis (AS), computed tomography (CT) remains the standard for …

Background Preprocedural 3-dimensional CT imaging of the aortic annular plane plays a
critical role for transcatheter aortic valve replacement (TAVR) planning; however, manual …

Objectives: We sought to compare 3 methods of measurements of the aortic annulus,
transthoracic echocardiography (TTE), transesophageal echocardiography (TEE), and …

Objectives: We compared the annulus diameters measured by transthoracic
echocardiography (TTE), transesophageal echocardiography (TEE), and dual‐source …

The success of transcatheter aortic valve replacement (TAVR) depends on the appropriate
evaluation of the aortic annulus because significant errors in sizing can lead to post …

Background Accurate preoperative assessment of the aortic annulus dimension is crucial for
successful transcatheter aortic valve implantation (TAVI). In this study we examined the …

Background Three-dimensional (3D) echocardiographic (3DE) imaging is an alternative to
multi–detector row computed tomography (MDCT) for aortic annular measurement before …

Objectives Sizing of the aortic valve is crucial for transcatheter aortic valve replacement
(TAVR). Multidetector computed tomography (MDCT) is used for sizing. Recently, three …

Aims: To evaluate the accuracy and reproducibility of aortic annulus sizing using a multislice
computed tomography (MSCT) based aortic root reconstruction tool compared with …
