Aortic root dimension changes during systole and diastole: evaluation with ECG-gated multidetector row computed tomography [PDF]
International Journal of Cardiovascular Imaging, 2011 Cardiac pulsatility and aortic compliance may result in aortic area and diameter changes throughout the cardiac cycle in the entire aorta. Until this moment these dynamic changes could never be established in the aortic root (aortic annulus, sinuses of ...

Diffusion MRI tractography of the human heart In Vivo at end-diastole and end-systole [PDF]
Journal of Cardiovascular Magnetic Resonance, 2012 Summary Diffusion Tensor MRI (DTI) of the human heart in vivo has to date been performed in 2D and at a single phase of the cardiac cycle. Here we perform 3D tractography of the human heart in vivo at both end diastole and end systole. We show that fiber

MDCT evaluation of dynamic changes in aortic root parameters during the cardiac cycle in patients with aortic regurgitation [PDF]
Scientific ReportsObjectives: To investigate the dynamic changes in multiple planes and parameters of the aortic root region at different phases of the cardiac cycle in patients with aortic regurgitation (AR) using multi-detector row computed tomography (MDCT). To provide

On the 2-Systole of Stretched Enough Positive Scalar Curvature Metrics on S2 times S2 [PDF]
Symmetry, Integrability and Geometry: Methods and Applications, 2020 We use recent developments by Gromov and Zhu to derive an upper bound for the 2-systole of the homology class of S 2 x { * } in a S 2 x S 2 with a positive scalar curvature metric such that the set of spheres homologous to S 2 x { * } is wide enough in ...

THE SIMPLE SEPARATING SYSTOLE FOR HYPERBOLIC SURFACES OF LARGE GENUS [PDF]
Journal of the Institute of Mathematics of Jussieu, 2020 In this note we show that the expected value of the separating systole of a random surface of genus g with respect to Weil–Petersson volume behaves like $2\log g $ as the genus goes to infinity.

Delineation and Analysis of Seismocardiographic Systole and Diastole Profiles [PDF]
IEEE Transactions on Instrumentation and Measurement, 2020 Precise estimation of fiducial points of a seismocardiogram (SCG) signal is a challenging problem for its clinical usage. Delineation techniques proposed in the existing literature do not estimate all the clinically significant points of an SCG signal ...
