Aims: The relationship between echocardiographic measures of left ventricular (LV) systolic function and reference-standard measures have not been assessed in children. The objective of this study was to assess the validity of echocardiographic indices of LV systolic function via direct comparison to a novel composite measure of contractility derived from pressure-volume loop (PVL) analysis. Methods and results: Children with normal loading conditions undergoing routine left heart catheterization were prospectively enrolled...

INTRODUCTION: Coronary microvascular dysfunction (MVD) may contribute to the pathogenesis of heart failure with preserved ejection fraction (HFpEF). Speckle-tracking echocardiography is a feasible and reproducible method for identifying abnormalities in left ventricular (LV) and left atrial (LA) function among HFpEF patients. By assessing myocardial flow reserve (MFR), positron emission tomography (PET) imaging enables quantitative assessment of coronary MVD. We hypothesized that, in patients with risk factors for HFpEF and normal epicardial perfusion on cardiac PET, abnormal MFR is associated with LV diastolic dysfunction (DD) and reduced LV and LA strain...

BACKGROUND: Although mechanical dyssynchrony parameters derived by speckle tracking echocardiography (STE) may predict response to cardiac resynchronization therapy (CRT), comparability of parameters derived with different STE vendors is unknown. METHODS: In the MARC study, echocardiographic images of heart failure patients obtained before CRT implantation were prospectively analysed with vendor specific STE software (GE EchoPac and Philips QLAB) and vendor-independent software (TomTec 2DCPA)...

Two-dimensional (2D) speckle tracking echocardiography represents a novel, simple and reproducible technique for the estimation of left ventricular myocardial deformation (strain) and the evaluation of left ventricular twist mechanics. During the last few years, its clinical and prognostic implications in cardiomyopathies and hypertrophic cardiomyopathy (HCM) in particular have been rapidly increasing. Reduced global longitudinal strain is associated with more severe disease and confers an increased risk for major cardiac events, independently of other clinical and echocardiographic risk factors...

Parameters using myocardial strain analysis may predict response to cardiac resynchronization therapy (CRT). As the agreement between currently available strain imaging modalities is unknown, three different modalities were compared. Twenty-seven CRT-candidates, prospectively included in the MARC study, underwent cardiac magnetic resonance (CMR) imaging and echocardiographic examination. Left ventricular (LV) circumferential strain was analysed with CMR tagging (CMR-TAG), CMR feature tracking (CMR-FT), and speckle tracking echocardiography (STE)...

AIMS: Diabetes is associated with higher arterial stiffness-an early marker of cardiovascular disease. The coupling between arterial stiffness and myocardial function is still unresolved. We investigate associations between arterial stiffness and early myocardial impairment assessed with advanced echocardiography. METHODS: In 305 type 1 diabetes (T1D) patients without known heart disease and with normal left ventricular ejection fraction (LVEF) (biplane LVEF > 45%), we measured arterial stiffness as pulse wave velocity (PWV) and performed conventional and speckle-tracking echocardiography assessing global longitudinal strain (GLS) as a measure of systolic myocardial function...

In chronic mitral regurgitation (MR) left atrium is one of the first cardiac structures that is involved in remodeling and ultrastructural changes for a progressive volume overload. Severe left atrial (LA) dilation on echocardiography and new onset of atrial fibrillation in asymptomatic patients with preserved Left Ventricular (LV) function, appeared as a Class IIb recommendation for consideration for surgical mitral valve repair in the actual guidelines. However, before atrial dilatation and dysfunction, several ultrastructural changes appear in the atrial muscle tissue that are difficult to identify with the standard echocardiography...

BACKGROUND: Asymptomatic left ventricular (LV) dysfunction is highly prevalent in type 2 diabetes patients. Unlike the other hypoglycemic drugs, SGLT2 inhibitors have shown potential benefits for reducing cardiovascular death and risk factors, aside from lowering plasma glucose levels. With this study we aim at determining whether the treatment with empagliflozin is associated with an improvement in LV functions in diabetic patients with asymptomatic LV dysfunction against Sitagliptin, which is presumably neutral on myocardial function...
