Strain Imaging and Ventricular Arrhythmia

Diagnostics, 2023
Ventricular arrhythmia is one of the main causes of sudden cardiac death. Hence, identifying patients at risk of ventricular arrhythmias and sudden cardiac death is important but can be challenging.

Left ventricular strain and strain rate in a general population [PDF]

European Heart Journal, 2008
Strain and strain rate (SR) are measures of deformation that reflect left ventricular (LV) function. To our knowledge, no previous study described these indexes in a general population. We therefore described peak-systolic strain and SR of the LV in the general population and derived diagnostic thresholds for these measurements in a healthy subgroup.In

Right ventricular involvement in anterior myocardial infarction: a tissue Doppler-derived strain and strain rate study [PDF]

Clinics, 2013
OBJECTIVE: Strain and strain rate imaging is currently the most popular echocardiographic technique that reveals subclinical myocardial damage. There are currently no available data on this imaging method with regard to assessing right ventricular ...

Structure-based finite strain modelling of the human left ventricle in diastole [PDF]

, 2013
Finite strain analyses of the left ventricle provide important information on heart function and have the potential to provide insights into the biomechanics of myocardial contractility in health and disease. Systolic dysfunction is the most common cause

Straining With the Ventricular Assist Device and Right Ventricular Function

Journal of the American College of Cardiology, 2013
We read with great interest the paper by Grant et al. ([1][1]) in which they provide an analysis to support the use of strain imaging as a unique echocardiographic measure to predict right ventricular (RV) failure in patients undergoing left ventricular assist device (LVAD) placement.

Left Ventricular Strain and Left Atrial Strain Are Impaired During Hemodialysis in Children [PDF]

The International Journal of Cardiovascular Imaging, 2021
Abstract Purpose We aimed to investigate intradialytic changes in ventricular and atrial function using speckle tracking echocardiography (STE) in pediatric hemodialysis (HD). Methods Children with HD vintage > 3 months were enrolled, and echocardiography was performed prior to, during, and after HD. STE was analyzed using GE EchoPAC. Left

Right ventricular strain in Fabry disease: Prognostic implications

International Journal of Cardiology, 2023
Left ventricular (LV) hypertrophy is the main feature of cardiac involvement in Anderson-Fabry disease (FD), but the right ventricle (RV) is also frequently affected. Previous studies failed to demonstrate an independent association between conventional parameters of RV performance and outcomes in FD.
