Advances in the imaging techniques of the heart have fueled the interest in understanding of right heart pathology. Recently, speckle tracking echocardiography has shown to aid in understanding various right heart diseases and better management. Its role is well established in diagnosing right heart failure, pulmonary artery hypertension, arrhythmogenic right ventricular dysplasia and congenita...

recurrent syncope of obscure etiology, particularly in those with structural heart diseases, is associated with higher mortality rates. there are insufficient and conflicting data on prevalence and etiology of syncope in the urban middle eastern population. evaluating the etiologic basis of syncope can be an effective step in prevention of morbidities and sudden cardiac death in susceptible pop...

Today, echocardiography is an essential non-invasive diagnostic imaging tool used in clinics worldwide. However, the application of ultrasound to heart began only about 70 years ago. In early 1950s, Hertz and Edler described use for myocardial walls mitral valve diseases. Feigenbaum (1960s) expanded clinical M-mode echocardiography. The advent two-dimensional (2D) (1970s), spectral Doppler colo...

Echocardiography is considered the primary diagnostic tool for congenital heart diseases. The pediatric echocardiography diagnostic errors, consisting of false positive or discrepant diagnoses, picked up within a 2.5-year period in our pediatric echocardiography laboratory are presented herein. In this case report, the factors contributing to the diagnostic errors are categorized as cognitive s...

In the current era of expanding catheter-based and complex repair procedures to treat aortic valve (AV) diseases, growing consideration is being given to understanding the functional anatomy of the AV complex. Echocardiography is the primary imaging modality to assess and follow-up AV diseases, and the recent three-dimensional (3D) capabilities allow clinicians to appreciate the functional comp...

introduction: cardiac dysfunctions have been well known in patients with major thalassemia. some studies have focused on differences in blood pressure and heart rate between these patients and normal population, while this view has not been proven in other studies. given the importance of hemodynamic factors in the health of these individuals, we intend to test the hypothesis as to whether or n...

background: there is some evidence indicating improvement in myocardial performance after atrial septal defect closure, either device closure or surgical, but ventricular dyssynchrony has not been evaluated before and after surgical closure. the aim of this study was to evaluate ventricular mechanical dyssynchrony in patients with atrial septal defect before and after surgical closure. methods:...

background : left ventricular (lv) dyssynchrony is a prevalent feature in heart failure (hf) patients. the current study aimed to evaluate the prevalence of inter and intraventricular dyssynchrony in hf patients with regard to the qrs duration and etiology. methods: the available data on the tissue doppler imaging (tdi) of 230 patients with refractory hf were analyzed. the patients were divided...
