The challenge of assessing heart valve prostheses by Doppler echocardiography.
The assessment of prosthetic valve function remains challenging. Echocardiography has become the key diagnostic tool not only because of its noninvasive nature and wide availability but also because of limitations inherent in alternative diagnostic techniques. Invasive evaluation is limited particularly in mechanical valves that cannot be crossed with a catheter, and in patients with both aorti...
متن کاملDoppler echocardiography in the study of patients with mitral disc valve prostheses.
A combination of M mode and Doppler echocardiography was used to study patients with mitral disc valve prostheses. The probe used in these investigations consisted of a circular Doppler crystal mounted around the M mode crystal in the same plane. Because of the strong echoes produced by the prosthesis the transducer (probe) could be angled for optimum Doppler signals without losing the M mode e...
متن کاملTissue Doppler Imaging versus Conventional Echocardiography in Evaluation of Cardiac Functions in Diabetes Mellitus
Background: Conventional echocardiography and tissue Doppler imaging have been highlighted to diagnose diastolic and systolic heart dysfunction. We aimed to compare tissue Doppler imaging with conventional echocardiography to diagnose heart dysfunctions in diabetes mellitus type 1 (DMT1) patients. <s...
متن کاملEvaluation of Right Ventricular Function by Tissue Doppler Echocardiography in Asthmatic Children
BackgroundAsthma is the most chronic inflammatory disorder of the airways in children and asthmatic patients can experience cardiac dysfunction, pulmonary hypertension and finally cor pulmonale later in life. We aimed to investigate Right Ventricular (RV) functions in asthmatic children by conventional and tissue Doppler echocardiography (TDE).Materials and Methods Pulmonary function tests, con...
متن کاملDoppler Tissue Echocardiography and Electrocardiography in Children with Celiac Disease Compared to Controls
Background Celiac disease (CD) is an autoimmune mediated gluten sensitive enteropathy and characterized by a wide range of clinical manifestations. The study aimed to compare Doppler tissue echocardiography findings between children with celiac disease and healthy children. Materials and Methods This case-control study was performed on 186 celiac and healthy children aged 6- 19 years. Celiac d...
