White Matter and Perivascular Imaging Changes in Alzheimer's Disease and Cerebral Amyloid Angiopathy

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Peak‐width of skeletonized mean diffusivity (PSMD) and diffusion tensor imaging–analysis along the perivascular space (DTI‐ALPS), reflecting white matter integrity and glymphatic function, are altered in Alzheimer's disease (AD).

Echocardiographic assessment of left atrial volume index in elderly patients with left ventricle anterior myocardial infarction

Heart Views, 2012
Introduction: Enlarged left atrium predicts outcomes in patients with heart failure, atrial fibrillation and stroke. Left atrial volume especially when corrected for body size, is a more accurate representation of true LA size.

Ventricular and Atrial Pressure—Volume Loops: Analysis of the Effects Induced by Right Centrifugal Pump Assistance

Bioengineering, 2022
The main indications for right ventricular assist device (RVAD) support are right heart failure after implantation of a left ventricular assist device (LVAD) or early graft failure following heart transplantation.

Quantification of left atrial volumes and left atrial function.

, 2016
Cine steady state free precession images are shown in the two- and four-chamber views at the point of maximum left atrial volume, before atrial contraction, and minimum left atrial volume. Length = Yellow, Area = Blue.

Protease‐Activated Theranostic Nanomedicine for Endometriosis Treatment

Advanced Functional Materials, EarlyView.
Endometriosis is a chronic gynecological disorder that affects a substantial proportion of reproductive‐aged women. In this study, we identify aberrant overexpression of matrix metalloproteinase‐9 (MMP‐9) in endometriotic lesions and develop a novel multifunctional nanomedicine that integrates MMP‐9‐targeted therapy, ratiometric photoacoustic (PA ...

Role of speckle tracking echocardiography in detecting early left atrial dysfunction in hypertensive patients

The Egyptian Heart Journal, 2018
Background: Arterial hypertension adversely affects left atrial (LA) size and function, effect on function may precede effect on size. Many techniques were used to assess LA function but with pitfalls.

Triplanar estimation of left atrial volume [PDF]

Journal of Cardiovascular Magnetic Resonance, 2011
Methods Consecutive atrial fibrillation (AF) patients referred for CMR to assess pulmonary veins and left atrial size prior to catheter based treatment were included. During the study period, patients without AF and minimal structural heart disease on CMR were also examined.
