چکیده

Background Imaging of the aortic annulus is paramount for the success of transcatheter aortic valve implantation (TAVI) to obviate prosthesis size mismatch. The aortic annulus is a dynamic structure with alterations of its ellipsoid shape during the cardiac cycle. The objective of this study was to investigate with cine-MRI the changes of the sagittal and coronal diameter of the aortic annulus and whether the point in time of measurement is relevant for prosthesis size selection.

Circumferential cyclic strain in the abdominal aorta: comparison of a phase-contrast magnetic resonance imaging vs. a FIESTA method

Introduction. Hemodynamic conditions such as low flow and wall shear stress are known to initiate and exacerbate vascular diseases; however, little is known about the circumferential cyclic strain experienced by the normal aorta. Circumferential strain is experienced by the vessel wall in response to stress from pulsatile blood flow and its attendant pressure wave and depends on wall constituen...

Left atrial aging: a cardiac magnetic resonance feature-tracking study.

Importance of left atrial (LA) phasic function evaluation is increasingly recognized for its incremental value in terms of prognosis and risk stratification. LA phasic deformation in the pathway of normal aging has been characterized using echocardiographic speckle tracking. However, no data are available regarding age-related variations using feature-racking (FT) techniques from standard cine ...

Measurement of vessel wall strain using cine phase contrast MRI.

PURPOSE To determine the feasibility of using magnetic resonance imaging (MRI) to non-invasively measure strain in the aortic wall. MATERIALS AND METHODS Cine phase contrast MRI was used to measure the velocity of the aortic wall and calculate changes in circumferential strain over the cardiac cycle. A deformable vessel phantom was used for initial testing and in vitro validation. Ultrasonic ...

Upper bound and numerical analysis of cyclic expansion extrusion (CEE) process

Deformation of the material during cyclic expansion extrusion (CEE) is investigated using upper-bound theorem. The analytical approximation of forming loads agrees very well with the FEM results for different amounts of chamber diameter, friction factor and also for lower die angles. However, the difference between analytical and numerical solution increases at higher die angles which are expla...

Numerical and Experimental Study on Ratcheting Behavior of Steel Cylindrical Shells with/without Cutout Under Cyclic Combined and Axial Loading

Ratcheting behavior of steel 304L cylindrical shell under cyclic combined and axial loading are investigated in this paper, numerically. Cylindrical shells were fixed oblique at angle of 20° and normal with respect to the longitudinal direction of the shell and subjected to force-controlled cycling with non-zero mean force, which causes the accumulation of plastic deformation or ratcheting beha...
