Convolutional Neural Network for the Detection of End-Diastole and End-Systole Frames in Free-Breathing Cardiac Magnetic Resonance Imaging

open access: yesComput. Math. Methods Medicine, 2017
Free-breathing cardiac magnetic resonance (CMR) imaging has short examination time with high reproducibility. Detection of the end-diastole and the end-systole frames of the free-breathing cardiac magnetic resonance, supplemented by visual identification,

A Pilot Study Evaluating LV Diastolic Function with M-Mode Measurement of Mitral Valve Movement in the Parasternal Long Axis View

open access: yesDiagnostics, 2023
This pilot study aimed to develop a new, reliable, and easy-to-use method for the evaluation of diastolic function through the M-mode measurement of mitral valve (MV) movement in the parasternal long axis (PSLA), similar to E-point septal separation ...

Analysis of left ventricular behaviour in diastole by means of finite element method [PDF]

open access: yes, 1979
The human left ventricle in diastole can be modelled as a passive structure with incremental internal pressure change being considered as the load. Recent developments in engineering stress analysis provide techniques for predicting the behaviour of ...

The diastolic dilemma. [PDF]

open access: yesBMJ, 1976
There is hopeless confusion in the English-speaking world about the determination of the diastolic blood pressure by sphygmo manometry. In Britain generations of students have been taught that the point of muffling of the Korotkow sounds (often referred to as the fourth phase) should be taken as the index of diastolic pressure, and until recently all ...

Effects of anesthesia on conventional and speckle tracking echocardiographic parameters in a mouse model of pressure overload [PDF]

open access: yes, 2015
Genetically‑modified mice are widely applied in cardiovascular studies as model organisms. Echocardiography is a key tool for evaluating cardiac and hemodynamic functions in mice.

Changes in left atrial deformation in hypertrophic cardiomyopathy: Evaluation by vector velocity imaging. [PDF]

open access: yes, 2012
OBJECTIVES: Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We assessed the global and regional left atrial (LA) function and its relation to left ventricular (LV) mechanics ...

Impaired coronary blood flow at higher heart rates during atrial fibrillation: investigation via multiscale modelling [PDF]

open access: yes, 2019
Background. Different mechanisms have been proposed to relate atrial fibrillation (AF) and coronary flow impairment, even in absence of relevant coronary artery disease (CAD). However, the underlying hemodynamics remains unclear.

Heart-like fair queuing algorithms (HLFQA) [PDF]

open access: yes, 2006
We propose a new family of fair, work conserving traffic scheduling mechanisms that imitate the behavior of the human heart in the cardiovascular system.

Comparison of diastolic function in children with transfusion dependent beta thalassemia major by tissue and conventional doppler imaging indices and its correlation with serum ferritin levels

open access: yesThe Turkish Journal of Pediatrics, 2019
Regular blood transfusions for children with beta thalassemia major (β- TM) results in iron overload cardiomyopathy/cardiac failure. Mortality in these children is most often because of heart failure.
