Clinical Utility of Systolic Left Ventricular Ejection Fraction in Atrial Fibrillation: Role of Prospective ECG-Triggered Cardiac CT.
Heart Rhythm
January 2025
Division of Cardiology, University of Ottawa Heart Institute, Canada. Electronic address:
Background: The assessment of left ventricular (LV) systolic function and quantification of LV ejection fraction (EF) in patients with atrial fibrillation (AF) can be difficult. We previously demonstrated that LV volume changes over the 100 ms of systole (LVEF) can be used as a measure of LV systolic function.
Objective: We sought to evaluate the applicability of LVEF in AF patients.
A First Diastolic Function Evaluation in the Personalized Exercise Prescription Program for Solid Organs Transplanted Subjects: Is Atrial Strain Useful?

Sport Medicine Centre, Clinical and Experimental Medicine, University of Florence, 50134 Florence, Italy.
: Solid organ transplant recipients (OTR) have been recently involved in exercise prescription programs in order to reduce the high prevalence of cardiovascular diseases. The normal systolic and diastolic cardiac function is fundamental to personalizing the prescription. Diastolic dysfunction can be associated to a higher risk of cardiovascular events and left atrial (LA) strain is an emerging parameter in the evaluation of diastolic compromising, especially in subjects with preserved ejection fraction.

J Am Soc Echocardiogr
January 2025
Department of Medicine and Surgery, University of Milano-Bicocca, Milan, Italy; Department of Cardiology, Istituto Auxologico Italiano, IRCCS, Milan, Italy.
Background: In patients with secondary tricuspid regurgitation (STR), right ventricular ejection fraction (RVEF) may not accurately reflect the actual RV systolic performance since a considerable amount of the RV stroke volume (SV) is regurgitated back into the right atrium. To overcome this limitation, we explored the association with the outcome of the effective RVEF (eRVEF), which accounts for the tricuspid regurgitant volume (RegVol).
Methods: 513 patients with STR (mean age 75±13 years, 39% atrial STR, 58% severe) underwent complete two-, three-dimensional, and Doppler echocardiography.
Left Ventricular Hemodynamic Forces Changes in Fabry Disease: A Cardiac Magnetic Resonance Study.
J Magn Reson Imaging
January 2025
Department of Cardiology, West China Hospital, Sichuan University, Chengdu, Sichuan, China.
Background: Hemodynamic force (HDF) from cardiac MRI can indicate subclinical myocardial dysfunction, and help identify early cardiac changes in patients with Fabry disease (FD). The hemodynamic change in FD patients remains unclear.
Purpose: To explore HDF changes in FD and the potential of HDF measurements as diagnostic markers indicating early cardiac changes in FD.
Echocardiogram utilization in hospitalized adults with isolated traumatic brain injury: Propensity-matched analysis of the national inpatient sample 2016-2020.
J Clin Neurosci
January 2025
Departments of Anesthesiology and Neurological Surgery, Harborview Medical Center, University of Washington, 325 9th Ave, Seattle, WA, 98104, USA.
Background: Early left ventricular systolic dysfunction is common after moderate-severe traumatic brain injury (TBI). Echocardiography (Echo) can evaluate cardiac function across various clinical scenarios; however, its utilization in isolated TBI remains poorly understood. To address this gap, we aim to examine Echo utilization in hospitalized adults with isolated TBI.
