Objectives: This study sought to investigate pulsatile changes of the aortic annulus and their
impact on prosthesis selection by computed tomography (CT). Background: Precise …

BACKGROUND: Accurate aortic root measurements and evaluation of spatial relationships
with coronary ostia are crucial in preoperative transcatheter aortic valve implantation …

Sizing for transcutaneous aortic valve replacement (TAVI) relies on non-invasive imaging.
Incorrect sizing may result in adverse outcomes including paraprosthetic regurgitation …

Accurate annular sizing in transcatheter aortic valve implantation (TAVI) planning is
essential. It is now widely recognized that the annulus is an oval structure in most patients …

Background The aim of this study was to assess the accuracy of a comprehensive
multidetector computed tomography (MDCT) evaluation of the aortic annulus (AoA) …

Background The complex anatomy of the aortic annulus warrants the use of three
dimensional (3D) modalities for prosthesis sizing in transcatheter aortic valve implantation …

Aortic valve stenosis is the most common valvular heart disease in the Western world. When
symptomatic, aortic valve stenosis is a debilitating disease with a dismal short-term …

Background—3D transesophageal echocardiography (TEE) may provide more accurate
aortic annular and left ventricular outflow tract (LVOT) dimensions and geometries compared …

Background—Identifying the optimal fluoroscopic projection of the aortic valve is important
for successful transcatheter aortic valve replacement (TAVR). Various imaging modalities …

Objective: Accurate preoperative assessment of the aortic annulus dimensions is critical in
patients undergoing transcatheter aortic valve implantation (TAVI) for severe AS. Using …
