Abstract Background Global longitudinal strain (GLS) derived from two-dimensional speckle-tracking echocardiography is feasible and accurate. However, in 2013, the landmark first Inter-Vendor Comparison Study showed significant differences of GLS results among vendors, providing a baseline for ongoing standardization efforts. In order to make tracking-based imaging clinically accepted useful parameter, it utmost importance have interchangeable accurate measurements all vendors. This report...
Abstract Background Hidden cardiotoxicity in adult survivors of childhood cancer may carry significant prognostic implications. Many these are asymptomatic at rest but show impaired cardiorespiratory fitness during exercise. Stress echocardiography combined with cardiopulmonary exercise testing (CPET) can reveal hidden diastolic dysfunction, although it presents major challenges. High frame rate (HFR) natural shear wave (SW) imaging is emerging as an innovative method for assessing...
Abstract Background Shear wave elastography (SWE), by measuring the propagation velocity of naturally occurring myocardial shear waves after mitral valve closure (MVC), provides real-time insights into stiffness. Previous studies have focused solely on patients with regular heart rhythm and investigated impact steady state loading conditions velocities (SWV). However, effect beat-to-beat variations in due to changes cardiac cycle length (CL) remains unknown. Purpose To investigate if SWV are...
Abstract Background Diastolic dysfunction with elevated end-diastolic pressures is a key component of Fontan circulatory failure. However, conventional echocardiographic parameters diastolic function do not correlate invasive in patients. Natural shear waves (SW) are emerging as novel parameter myocardial stiffness, determinant function. Purpose We investigated the relationship between natural SW velocities and Methods patients were prospectively recruited from single center. They underwent...
Abstract Background Current conventional echocardiographic assessment of diastolic function relies on predicting left ventricular (LV) filling pressure as a surrogate function. However, the current guidelines algorithm for estimation LV pressures is complex. High frame rate (HFR) Shear wave (SW) imaging emerging novel parameter assessing myocardial stiffness, key determinant Natural SW can be induced, e.g., by mitral valve closure (MVC) and their propagation speed directly related to...
Abstract Introduction Cardiac Shear Wave Elastography utilizes ultrafast echocardiographic imaging to assess myocardial stiffness through the propagation velocities of shear waves (SWs). Despite advancements, variability in SW speed measurements remains a challenge. Current assessment lacks gold standard method and still relies on subjective visual with manual leading inherent variability. Purpose Manual nine semi-automatic algorithms for measuring were systematically tested, aiming reduce...
Abstract Background Myocardial fibrosis has important clinical and prognostic implications. Cost-effective imaging tools for screening to enable personalized therapies are thus of major interest. Echocardiographic shear wave (SW) elastography is an emerging approach measuring myocardial stiffness (MS). SWs occur after mechanical excitation the myocardium, e.g. mitral valve closure (MVC,i.e natural SW), their propagation velocity directly related MS. Purpose To investigate if SW velocities...
Abstract Background Cardiac shear wave elastography (SWE) allows for the non-invasive assessment of myocardial stiffness via detection waves (SW) travelling through heart after e.g. mitral valve closure (MVC). The propagation speed these is directly related to stiffness. Myocardial operational depends on intrinsic properties myocardium as well loading conditions heart. Therefore, changing conditions, example volume unloading under diuretics, could influence SW speed. Purpose To evaluate...
Radiofrequency ablation (RFA) appears effective for the treatment of hepatocellular carcinoma (HCC). Evaluation prognostic factors is imperative patient selection and improving efficacy. This study aimed to assess sarcopenia as a predictor outcome RFA in patients with HCC.This prospective included all HCC on top HCV-related cirrhosis who underwent followed up minimum two years. CT scan was used determine skeletal muscle index at psoas, erector spinae, quadratus lumborum, transversus...
The objective of the study was to translate Sino-Nasal Outcome Test 22 (SNOT-22) into Arabic and check its reliability validity in Arabic-speaking patients. included 178 patients with confirmed chronic rhinosinusitis (CRS) 95 asymptomatic individuals as a control group. All participants completed SNOT-22 (A-SNOT-22) questionnaire. scores two groups were compared for analysis. Eighty-two questionnaire twice, 1 week apart, test-to-test A-SNOT-22 60 CRS correlated Lund–Mackay criterion...
Adipose tissues synthesize and secrete various proinflammatory anti-inflammatory mediators, termed cytokines. This work aims to assess different serum urinary cytokine levels before 12 months after laparoscopic sleeve gastrectomy (LSG).This prospective study was performed on 61 obese non-diabetic patients who underwent LSG. All were followed up postoperatively at with the assessment of arterial blood pressure, microalbuminuria, inflammatory cytokines (macrophage migration inhibitory factor...

Abstract Introduction Cardiac Shear Wave Elastography is an emerging non-invasive technique using ultrafast echocardiographic imaging. Natural shear waves (SW) occur after mitral valve closure (MVC) and aortic (AVC), their propagation velocities are directly related to myocardial stiffness. However, the current assessment of SW lacks a gold standard method, relies on manual measurements with inherent variability. Purpose To explore new automated methods for wave velocity estimates, aiming...

Abstract Background Diastolic dysfunction is thought to be the earliest cardiotoxic sequel after cancer therapy among childhood survivors. Despite many survivors do exhibit reduced cardiorespiratory fitness (CRF) potentially due cardiotoxicity, current echocardiographic parameters fail detect hidden diastolic early (1).
