Objectives Computed tomography (CT) provides excellent anatomy assessment of the aortic
annulus (AoA) and is utilized for pre-procedural planning of transcatheter aortic valve …

Background The purpose of this study was to quantify and characterize aortic valve leaflet
and aortic annular calcification with computed tomography angiography (CTA) and to define …

BACKGROUND: We compared the midterm outcome after aortic valve replacement with the
Freestyle stentless bioprosthesis for the full-root or subcoronary implantation technique …

Catheter-based aortic valve implantation is increasingly being performed in high-risk
patients with symptomatic aortic valve stenosis. For successful planning of the procedure …

Purpose To prospectively determine whether cardiac-gated multidetector computed
tomography (CT) allows visualization of aortic valve leaflets after bioprosthetic aortic valve …

Objective It is intuitive to suggest that knowledge of the variation in the anatomy of the aortic
root may influence the outcomes of transcatheter implantation of the aortic valve (TAVI). We …

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

Background Significant paravalvular aortic regurgitation (PAR) after transcatheter aortic
valve implantation (TAVI) is associated with negative clinical consequences. We …

OBJECTIVE. The objective of our study was to investigate the feasibility, image quality, and
clinical implications of a combined dual-source CT angiography (CTA) protocol to assess …

Objectives: Using multislice computed tomography (MSCT), we sought to evaluate the
geometry and apposition of the CoreValve ReValving System (CRS, Medtronic …
