Background: Evaluation of left ventricle (LV) systolic function in patients with aortic stenosis (AS) undergoing transcatheter aortic valve implantation (TAVI) is challenging, as LV ejection fraction (LVEF) and global longitudinal strain are afterload ...

Anatomic reconstruction of recurrent aortic arch obstruction in children [PDF]
Objective: Anatomical reconstruction of the aortic arch following aortic arch surgery is challenging. The placement of an extra-anatomical aortic bypass has been proposed for these difficult cases.

4D Flow MRI Velocity and Turbulence Mapping in Mild Valvular Heart Disease
ABSTRACT Background Valvular heart disease (VHD) commonly leads to the development of turbulent blood flow. Turbulent kinetic energy (TKE), measured with 4D flow MRI, may be a complement to current metrics for early identification of VHD. Purpose To investigate TKE as a marker of VHD in relation to flow velocity and cardiovascular geometry.

ABSTRACT Background Carotid artery stenosis is a major cause of stroke. Non‐contrast MR angiography (MRA) using time‐spatial labeling inversion pulse (Time‐SLIP) may offer potential advantages over 3D time‐of‐flight (TOF)‐MRA for simultaneous visualization of carotid, vertebral, and subclavian arteries, but remains uninvestigated.

Abstract Purpose This study investigated the effect of bicuspid aortic valve (BAV) morphology and ascending aortic curvature (AAAc) bending angles on aortic hemodynamics, focusing on transvalvular jets and secondary helical flows that contribute to systolic hemodynamic stress linked to aortic complications.
