A Meshless Modeling of Dynamic Strain Localization in Quasi-Brittle Materials Using Radial Basis Function Networks [PDF]

, 2008
This paper describes an integrated radial basis function network (IRBFN) method for the numerical modelling of the dynamics of strain localization due to strain softening in quasi-brittle materials.

The use of deformation imaging in the assessment of patients pre and post transcatheter aortic valve implantation

Echo Research and Practice, 2023
Background Deformation imaging represents a method of measuring myocardial function, including global longitudinal strain (GLS), peak atrial longitudinal strain (PALS) and radial strain.

Three‐Dimensional Global Left Ventricular Myocardial Strain Reduced in All Directions in Subclinical Diabetic Cardiomyopathy: A Systematic Review and Meta‐Analysis

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021
Background Three‐dimensional (3D) speckle tracking echocardiography can identify subclinical diabetic cardiomyopathy without geometric assumption and loss of speckle from out‐of‐plane motions.

CMR-based right ventricular strain analysis in cardiac amyloidosis and its potential as a supportive diagnostic feature

International Journal of Cardiology: Heart & Vasculature, 2023
Background: Right ventricular (RV) strain has provided valuable prognostic information for patients with cardiac amyloidosis (CA). However, the extent to which RV strain and strain rate can differentiate CA is not yet clinically established.

Left ventricular strain patterns and their relationships with cardiac biomarkers in hypertrophic cardiomyopathy patients with preserved left ventricular ejection fraction

Frontiers in Cardiovascular Medicine, 2022
AimsThis study aims to assess left ventricular (LV) function in hypertrophic cardiomyopathy (HCM) patients with preserved left ventricular ejection fraction (LVEF) by LV strain patterns based on cardiac magnetic resonance feature tracking (CMR-FT) and to

Three-dimensional versus two-dimensional strain for the assessment of myocardial function: A case series

Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2017
Introduction: Two-dimensional (2D) strain assessment is an important diagnostic and prognostic tool in various clinical conditions, particularly coronary artery disease (CAD). However, these measurements are limited in that the information is obtained in

The additive effects of kidney dysfunction on left ventricular function and strain in type 2 diabetes mellitus patients verified by cardiac magnetic resonance imaging

Cardiovascular Diabetology, 2021
Background Patients with type 2 diabetes mellitus (T2DM) are susceptible to coexisted with chronic kidney disease (CKD), which may increase cardiovascular mortality in these patients.

Left ventricular radial strain impairment precedes hypertrophy in Anderson-Fabry disease

, 2020
In Anderson-Fabry disease (AFD), left ventricular (LV) radial function has been scarcely investigated. We hypothesized that LV function may be affected by disease specific mechanisms and sought to comprehensively evaluate LV radial, circumferential and ...

Characteristics and prognostic value of cardiac magnetic resonance strain analysis in patients with different phenotypes of heart failure

Frontiers in Cardiovascular Medicine
BackgroundStrain analysis of cardiac magnetic resonance imaging (CMR) is important for the prognosis of heart failure (HF). Herein, we aimed to identify the characteristics and prognostic value of strain analysis revealed by CMR in different HF ...
