OBJECTIVE: Percutaneous aortic valve replacement is an emerging therapy for selected
patients with severe aortic stenosis. Preoperative imaging of the aortic root facilitates sizing …

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 aim of this study was to characterize aortic root dimensions of patients with
aortic valve stenosis undergoing transcatheter aortic valve replacement (TAVR) and to …

Detailed knowledge of aortic root geometry is a prerequisite to anticipate complications of
transcatheter aortic valve (TAV) implantation. We determined coronary ostial locations and …

Methods: The study included 32 patients referred for TEE for suspected cardiac sources of
emboli, but diagnosed as normal. Images of the aortic valve in long axis (100-120∞) and …

Background To enhance the reproducibility of aortic valve–sparing reimplantation and
annuloplasty, we analyzed the topographic relationship between the ventriculoaortic …

OBJECTIVE: Transcatheter aortic valve implantation is an emerging technique for the
treatment of aortic valve stenosis in high-risk patients. Detailed knowledge of aortic root …

The purpose of the present study was to compare the aortic valve area, aortic valve annulus,
and aortic root dimensions measured using magnetic resonance imaging (MRI) with …

The current transcatheter aortic valve implantation (TAVI) devices have been designed to fit
Caucasian and Latin American aortic root anatomies. We evaluated the racial differences in …

Methods Under cardiopulmonary bypass, sonomicrometry crystals were implanted in the
aortic root and valve of eight sheep. Crystals were sutured at each commissure (n= 3), the …
