Scaling temporal resolution from mice to humans: Challenges and innovations in preclinical imaging of translational models

The Journal of Physiology, EarlyView.
Abstract figure legend Temporal scaling physiology differs significantly between mice and humans. Mice have higher metabolism, heart and respiratory rate, as well as faster blood flow rates, brain activity and physiological dynamics over time. These differences influence the temporal resolution needed in preclinical imaging of mouse models to ...

Speckle tracking echocardiography - Quo Vadis?

Circulation journal : official journal of the Japanese Circulation Society, 2015
Although echocardiography is a noninvasive means of visualizing the heart, quantitative and reproducible assessment of myocardial motion remains to be established. Tissue Doppler imaging (TDI) emerged in the early 1990 s as a tool to measure tissue motion velocity.

P2X3 receptor antagonism improves hindlimb blood flow during exercise in a conscious ovine model of hypertensive heart failure with preserved ejection fraction

The Journal of Physiology, EarlyView.
Abstract figure legend A preclinical large‐animal model of hypertensive heart failure with preserved ejection fraction (HFpEF) was used to examine the role of purinergic P2X3 receptor signalling during treadmill exercise. Animals were instrumented with either thoracic cardiac output and coronary flow probes or abdominal renal and hindlimb blood flow ...

Impact of mitral regurgitation on left atrial appendage functions: the efficacy of speckle tracking echocardiography

BMC Cardiovascular Disorders
Purpose We aimed to evaluate left atrial appendage functions (LAA) derived by speckle tracking echocardiography in patients with mild to severe mitral regurgitation (MR) and assess the relation between MR severity and LAA’s anatomical, structural, and ...

How do I do it? Speckle-tracking echocardiography

Indian Heart Journal, 2013
Speckle-tracking echocardiography (STE) is a recently developed technique for the characterization and quantification of myocardial deformation. By allowing measurement of the different components of myocardial deformation, it provides information which is not available with any of the currently used echocardiographic parameters, including left ...

Permanent Cardiac Pacing in Children: A 30‐Year Follow‐Up Retrospective Study in a Single Pediatric Asian Center

Journal of Arrhythmia, Volume 42, Issue 5, October 2026.
This 30‐year retrospective study of pediatric permanent pacing found acceptable long‐term device complication rates, with epicardial leads used predominantly. Pacing‐induced cardiomyopathy occurred only in children with congenital heart disease, highlighting the need for individualized pacing strategies in this cohort and long‐term echocardiographic ...

A novel speckle-tracking echocardiography parameter assessing left ventricular afterload

, 2023
BACKGROUND: Left ventricular stroke work index (LVSWI) and afterload-related cardiac performance (ACP) consider left ventricular (LV) afterload and could be better prognosticators in septic cardiomyopathy.
