Cardiovascular diseases are the most common cause of mortality in world. Currently, type 2 diabetes mellitus (T2DM) is one main risk factors for major adverse cardiovascular events. T2DM patients have a four-fold higher developing heart failure and 10 to 12 times mortality. Echocardiography all its modalities best clinical tool diagnosis, since it provides static dynamic images that allow ident...
Two consecutive series of patients with a T wave asymmetry ratio of 2.0 or greater have been studied. Patients with bundle-branch block or who were on digoxin or a similar drug were excluded. In 50 of the 69 patients, the heart was examined either by echocardiography or by direct inspection. Sixty-one of the 69 patients had diseases commonly associated with left (or right) ventricular hypertrop...

A unique and highly versatile technique, stress echocardiography (SE) is increasingly recognized for its utility in the evaluation of non-ischaemic heart disease. SE allows for simultaneous assessment of myocardial function and haemodynamics under physiological or pharmacological conditions. Due to its diagnostic and prognostic value, SE has become widely implemented to assess various condition...
Our understanding of the molecular and pathophysiological mechanisms underlying the disease process in patients with b-thalassemia intermedia has substantially increased over the past decade. Earlier studies observed that patients with b-thalassemia intermedia experience a clinical-complications profile that is different from that in patients with b-thalassemia major. In this article, a variety...
background: increasing frame rate is a challenging issue for better interpretation of medical images and diagnosis based on tracking the small transient motions of myocardium and valves in real time visualization. methods: in this paper, manifold learning algorithm is applied to extract the nonlinear embedded information about echocardiography images from the consecutive images in two dimension...
Background Iron chelation treatment has increased life expectancy of patients with beta thalassemia major. Accurate assessement of heart iron overload is essential for managing chelation therapy. Nowadays, MRI-based iron overload quantification became the gold standard technique. However it remains too expensive in countries that cannot afford such technology, which ironically are endemic count...
TEE applications for children and infants with congenital heart disease are now clinically established and TEE is being used in most major pediatric cardiovascular centers. This technology has evolved to the point that it is capable of providing diagnostic quality imaging, even for small infants. With expanding technology and increasing experience, new and more sophisticated applications will b...
Echocardiography has become the primary imaging tool in the diagnosis and assessment of congenital and acquired heart disease in infants, children, and adolescents. Transthoracic echocardiography (TTE) is an ideal tool for cardiac assessment, as it is noninvasive, portable, and efficacious in providing detailed anatomic, hemodynamic, and physiologic information about the pediatric heart. Recomm...
