Application prospect of speckle tracking echocardiography in pacemaker implantation

Frontiers in Cardiovascular Medicine
More than 1 million permanent pacemakers are implanted worldwide each year, half of which are in patients with high-grade atrioventricular block. Pacemakers provide adequate frequency support in the initial stage, but traditional right ventricular (RV) pacing may lead to or aggravate left ventricular dysfunction and arrhythmia.

Left Atrial Reservoir Strain and Heart Failure Rehospitalization Burden in Acute Heart Failure With Atrial Fibrillation

Echocardiography, Volume 43, Issue 9, September 2026.
This graphical abstract summarizes 716 patients with acute heart failure and atrial fibrillation. The left atrial diameter analysis included 691 patients (189 rehospitalization‐first, 118 death‐first, 384 censored); volume index and reservoir strain were available in a 320‐patient single‐center subgroup.

Speckle Tracking Echocardiography of the Right Atrium: The Neglected Chamber

, 2015
The right atrium (RA) plays a pivotal role in electromechanical and endocrine regulation of the heart. Its peculiar anatomical features and phasic mechanical function make it distinct from ventricles. Various invasive and noninvasive techniques have been

Artificial Intelligence–Based Echocardiographic Assessment of Diastolic Dysfunction: A Systematic Review

Echocardiography, Volume 43, Issue 9, September 2026.
AI‐based echocardiographic assessment of diastolic dysfunction demonstrates moderate‐to‐high diagnostic discrimination against invasive and guideline‐based reference standards and consistently resolves indeterminate classifications. Prospective multicenter validation, calibration reporting, and clinical impact data are required before routine adoption.

Non‐Invasive Assessment of Endothelial Dysfunction and Arterial Stiffness in Fontan Circulation

European Journal of Clinical Investigation, Volume 56, Issue 9, September 2026.
The Fontan procedure is the definitive treatment for complex congenital heart disease, creating a circulation without a subpulmonary ventricle. This altered hemodynamic state negatively affects endothelial function, contributing to progressive organ dysfunction and long‐term morbidity.

Multidomain Arterial Afterload and Left Atrial–Left Ventricular Coupling in Hypertensive Phenotypes

The Journal of Clinical Hypertension, Volume 28, Issue 9, September 2026.
ABSTRACT Brachial blood pressure may not fully reflect the multidimensional arterial load associated with left atrial–left ventricular (LA–LV) coupling. In this cross‐sectional study, we examined local carotid pulse wave velocity (PWV), cuff‐derived arterial pressure–volume index (API), and arterial velocity–pulse index (AVI), separately and as a ...

Physiologically‐Guided Ultrafiltration: A Proposed Ultrasound Framework for Individualized Volume Removal During Hemodialysis

Nephrology, Volume 31, Issue 9, September 2026.
ABSTRACT Ultrafiltration during hemodialysis is the most hemodynamically stressful intervention dialysis patients endure, yet its prescription relies on interdialytic weight gain and clinical gestalt. Rates exceeding 13 mL/kg/h carry substantially higher cardiovascular mortality, and recurrent intradialytic hypotension drives myocardial stunning ...

Speckle tracking Echocardiography is a sensitive tool for the detection of myocardial ischemia : A pilot study from the catheterization laboratory during percutaneous coronary intervention

, 2007
Analysis of rotational myocardial motion has been reported to be a sensitive index of myocardial ischemia. In this study, circumferential and radial myocardial strain and displacement was monitored during angioplasty balloon-induced myocardial ischemia ...

Ultrasound‐based haemodynamic force trajectories in a murine model of reversible pressure overload

The Journal of Physiology, Volume 604, Issue 17, Page 7092-7111, 1 September 2026.
Abstract figure legend High‐resolution ultrasound anatomical imaging and speckle‐tracking analysis were used to compute left ventricular (LV) haemodynamic forces (HDF) in a murine model of transverse aortic constriction (TAC) followed by aortic debanding (deTAC).
