Heart disease is the leading cause of hospitalization and death worldwide, severely affecting health care costs. Aging is a significant risk factor for heart disease and the senescent heart is characterized by structural and functional changes including diastolic and systolic dysfunction as well as left ventricular (LV) dyssynchrony. Speckle-tracking based strain echocardiography (STE) has been shown as a non-invasive, reproducible and highly sensitive methodology to evaluate LV function in both animal models and humans...

Speckle tracking echocardiography offers a unique opportunity to evaluate myocardial function, and global longitudinal strain (GLS) is currently recommended as a measurement of global left ventricular function. To facilitate clinical applicability of the method, collective efforts have been made to standardise strain measurements and to raise awareness of the potential sources of variability. The purpose of this review is to familiarise the reader with the most common sources of variability of longitudinal strain measurements and detail the possible measures to increase the accuracy and reproducibility of strain parameters...

Background and objectives: Right ventricular (RV) pacing can lead to progressive ventricular dysfunction over a certain period. This pacemaker-induced cardiomyopathy (PiCMP) may be more common than previously reported. Speckle tracking imaging is a recent development in echocardiography that can identify left ventricular (LV) dysfunction even before the LV ejection fraction (LVEF) value decreases. Three-dimensional (3D) echocardiography has made more accurate assessment of LVEF possible...

Speckle tracking echocardiography (STE) is increasingly used during functional assessments. However, reproducibility and dependence on echocardiographic image quality for speckle tracking stress echocardiography in pediatric patients have not been studied to date. 127 consecutive normotensive children without structural heart disease (mean age 13.4 ± 3.0 years, 50.4% female) underwent a stepwise semisupine cycle ergometric protocol. Left ventricular (LV) myocardial peak strain and strain rate were assessed at rest and during exercise...

BACKGROUND: Late after tetralogy of Fallot (TOF) repair some patients exhibit aortic dilatation and stiffness. Noninvasive assessment of aortic stiffness could contribute to understand this aortopathy and may be important in risk stratification for major aortic event. METHODS: We included prospectively 82 adults after TOF repair and 41 age- and sex-matched normal controls. Aortic diameters were measured by two-dimensional transthoracic echocardiography and the aortic z-score was estimated...

AIM: Left atrial (LA) fibrosis promotes atrial fibrillation (AF), may predict poor radiofrequency catheter ablation (RFCA) outcome, and may be assessed invasively using electroanatomical mapping (EAM). Speckle tracking echocardiography (STE) enables quantitative assessment of LA function. The aim was to assess the relationship between LA fibrosis derived from EAM and LA echocardiographic parameters as well as biomarkers of fibrosis in patients with AF. METHODS: Sixty-six patients (64% males, mean age 56 ± 10) with nonvalvular AF treated with first RFCA were prospectively studied...

Background: Cardiotoxicity is one of the most serious chronic complications of anthracyclines therapy. Assessment of the left ventricular ejection fraction (LVEF) fails to detect subtle cardiac dysfunction of left ventricular (LV). This study aimed to detect and evaluate new parameters of subclinical anthracyclines' cardiotoxicity in children with solid tumor. Methods: A detailed echocardiographic examination was performed in 36 children with hepatoblastoma or rhabdomyosarcoma after receiving anthracyclines' chemotherapy and 36 healthy controls from January 2015 to December 2016...

BACKGROUND AND AIMS: Few studies have shown the direct effect of familial hypercholesterolemia (FH) on myocardial systolic function. Studies focused on heterozygote FH patients but not homozygote ones, and they did not perform genetic analyses. We aimed to evaluate all types of patients with FH using the potentially more sensitive speckle tracking echocardiography (STE) technique to identify early left ventricular (LV) dysfunction. METHODS: Genetic analyses of patients with FH were conducted for LDL-receptor, PCSK9, and ApoB100...

The etiology of dilated cardiomyopathy (DCM) can be grouped as either genetic or nongenetic. More than 50 pathogenic genes have been described, with sarcomeric and lamin A/C mutations being the most common. Mutation carriers for genetic DCM are often asymptomatic until cardiac disease manifests with heart failure, arrhythmias, or sudden cardiac death. Preventive strategies are promising but can only be applied and tested adequately if genetic DCM can be diagnosed at an early stage. Early diagnosis of mutation carriers that may develop overt DCM requires advanced imaging techniques that can detect subtle structural and functional abnormalities...
