Objectives To evaluate the effectiveness of CT before TAVI using variable helical pitch
(VHP) scanning and its diagnostic performance for coronary artery disease (CAD). Methods …

Objective: To evaluate feasibility, image quality and accuracy of a reduced contrast volume
protocol for pre-procedural CT imaging in transcatheter aortic valve implantation (TAVI) …

Abstract Objectives Transcatheter Aortic Valve Implantation (TAVI) is an alternative to
surgical valve replacement in high risk patients. Angiography of the aortic root, aorta and …

Objective: To evaluate the clinical value of 3D rotational angiography, as a tool for imaging
and measuring 3D anatomy, coupled with transesophageal echocardiogram (TEE) as …

The choice of preferred access route for transcatheter aortic valve implantation (TAVI) is
mainly guided by the minimal aorto-femoral tract diameter. Currently, projection angiography …

Purpose To evaluate the feasibility, image quality (IQ) and diagnostic performance of third
generation 192× 2 dual source computer tomography (DSCT) with ultra-high pitch …

Objectives Computed tomography angiography (CTA) is performed routinely in the work-up
for transcatheter aortic valve implantation (TAVI), and could potentially replace invasive …

Background Coronary CT has become the foremost noninvasive imaging modality for
detecting coronary stenoses in patients with suspected coronary artery disease …

Aims Repeated angiograms to achieve an exactly orthogonal visualization of the aortic valve
plane can substantially contribute to the total contrast amount required for transcatheter …

Background Computed tomography angiography (CTA) is used to plan TAVI procedures.
We investigated the performance of pre-TAVI CTA for excluding coronary artery disease …
