Abstract Introduction The left atrium (LA)’s essential function is modulating ventricular (LV) filling via its different reservoir, conduit, and contractile functions. This could be accurately achieved now by dedicated speckle-tracking echocardiography software. Methodology We included in this prospective cohort study 200 subjects with structurally normal hearts, who present for elective echoca...

AIMS To evaluate the impact of acoustic window on the feasibility and accuracy of longitudinal global strain (global-ε) by speckle tracking for assessing left ventricular (LV) systolic function. METHODS AND RESULTS The study included 70 patients (57 ± 17 years, 64% men), 28 selected patients with a suboptimal image quality (IQ) defined by three or more segments (4 ± 3 segments/patient) with w...

OBJECTIVE The aim of the present study was to evaluate left atrial (LA) volume and functions using real-time three-dimensional echocardiography (RT3DE) and speckle tracking in systemic sclerosis (SSc) patients. METHODS The study was designed as a cross-sectional observational study. We studied 41 consecutive SSc patients (38 females, mean age: 49.5±11.6 years) and 38 healthy controls (35 fema...

The strain and strain-rate measures are commonly used for the analysis and assessment of regional myocardial function. In echocardiography (EC), the strain analysis became possible using Tissue Doppler Imaging (TDI). Unfortunately, this modality shows an important limitation: the angle between the myocardial movement and the ultrasound beam should be small to provide reliable measures. This con...

BACKGROUND Sickle cell disease (SCD) is a hemoglobinopathy that is common worldwide. It usually presents with cardiac involvement, although data on systolic function are somewhat controversial. The aim of this study was to investigate the value of speckle-tracking strain, a deformation index, in detecting ventricular dysfunction in SCD. METHODS Ninety adult patients with SCD were compared wit...

BACKGROUND Recently, genetic studies have suggested a causal relationship between cholesterol remnants and ischemic heart disease. We aimed to determine whether cholesterol remnants and its marker, triglyceride levels, are associated with cardiac function as determined by sensitive echocardiographic measures in a population of patients with type 2 diabetes. METHODS Comprehensive echocardiogra...

AIMS Although dipyridamole is a widely used pharmacological stress agent, the direct effects on myocardium are not entirely known. Diabetic cardiomyopathy can be investigated by 2D-strain echocardiography. The aim of this study was to assess myocardial functional reserve after dipyridamole infusion using speckle-tracking echocardiography. METHODS Seventy-five patients referred for dipyridamol...

Background: The left ventricular (LV) chamber size and its systolic function is the most common quickest assessment made by echocardiography, either in intra operative or intensive care setting, being pressure generator for blood supply to body .Congenital cardiac defects come two main types: atrial septal (ASD/VSD). Regression spontaneous closure may be natural course of minor defects.
