background many types of cardiovascular complications such as; cardiac arrhythmias, impaired cardiac function, myocardial ischemia and decreased left ventricular function, have been attributed to interferon therapy. objectives the aim of this study was to evaluate the effects of combination therapy pegylated interferon and ribavirin on left ventricular systolic and diastolic functions in patien...
The objective of the VES project is the research and development of innovative techniques and solutions for the achievement of a virtual examination environment in echocardiography. One crucial point is the development of realistic geometric models representing the diseased human heart. For this purpose we decided to use real echocardiography findings as a starting position. The modelling and v...
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...
L'echocardiographie trouve de plus en plus une place importante dans L'evaluation des diverses cardiopathies tant acquises que Congenitales. Cette technique, non sanglante et atraumatique a surtout l'intcrrct de Pouvoir etre repete a volonte. Ainsi l'echoc'.lrdiographie rend de servic-:: certains dans L'etablissement du bilan preoperatoin: des cctrdiooathies valvulaires sifrequente en Ir...
conclusions these studies will enable physicians to diagnose and follow up many cardiac diseases when this software is interfaced within echocardiographic machines. results myocardial fibers initiate from the posterior basal region of the heart, continue through the left ventricular free wall, reach the septum, loop around the apex, ascend, and end at the superior-anterior edge of the left vent...
Objective- The purpose of this study was to investigate the feasibility of performing echocardiography in apparently healthy pigeons, and measurement of the quantitative cardiac indices using B-mode and Doppler techniques. Design- Experimental study Animals- Ten apparently healthy pigeons Procedures- Echocardi...
Introduction: Among malignant pericardial tumors, which appear to be scarcely seen, primary pericardial angiosarcoma is considered as one of the rarest ones. Case Report: A 51-year-old female presented with dyspnea on exertion and edema of lower limbs. Echocardiography showed pericardial effusion. Aspiration and biopsy of pericardium were reported as chronic pericarditis as well. In her thi...
Abstract Background: Impedance cardiography (ICG) is a simple and inexpensive technique for non-invasive and continues measurement of stroke volume. Due to non-invasive nature, ICG is becoming increasingly used in research and clinical applications. With regard to lack of domestic impedance cardiograph and limited similar imported products in the country, an inexpensive and portable protot...
