Contrast echocardiography for left ventricular opacification
نویسندگان
چکیده
E chocardiography has been criticised of having only moderate reproducibility and of having a low sensitivity of changes in left ventricular ejection fraction (LVEF). Inadequate endocardial visualisation during echocardiography occurs in up to 20% of cases. Although image quality has been improved with the introduction of harmonic imaging, 2 there are still a number of studies remaining of inadequate quality, and it is here that the use of contrast agents comes into its own. A number of studies have now been performed looking at the effect of contrast on assessment of cardiac regional and global function. This paper reviews the current and future clinical use of ultrasound contrast agents for assessment of left ventricular function.

Contrast Enhanced Echocardiography for Detection of Intrapulmonary Shunts in Liver Transplant Candidates
Background: Intrapulmonary vascular abnormalities associated with liver cirrhosis may result in intrapulmonary right-to-left shunt and hypoxemia. The aim of this study was to use contrast enhanced echocardiography to detect intrapulmonary vascular abnormalities in patients with liver cirrhosis candidates for liver transplantation. Methods: One hundred and two adult patients underwent contrast e...
متن کاملContrast echocardiography for left ventricular opacification.
Intravenous contrast agents are clinically useful for objective assessment of left ventricular (LV) regional and global function in patients with sub-optimal echocardiography images. Recent concerns over the safety of second generation microbubble contrast agents have now been largely abated with the emergence of robust clinical data supporting its safety and clinical utility. With proper techn...

OBJECTIVES Myocardial contrast echocardiography is useful to assess myocardil perfusion, but myocardial opacification is affected by the setup of the ultrasonic equipment. The optimal setting of focus points for adequate opacification of the myocardium was examined in myocardial contrast echocardiography. METHODS Myocardial contrast echocardiography was performed in six dogs using triggered s...
متن کاملCombination of contrast with stress echocardiography: A practical guide to methods and interpretation
Contrast echocardiography has an established role for enhancement of the right heart Doppler signals, the detection of intra-cardiac shunts, and most recently for left ventricular cavity opacification (LVO). The use of intravenously administered micro-bubbles to traverse the myocardial microcirculation in order to outline myocardial viability and perfusion has been the source of research studie...
متن کاملTwo-dimensional contrast echocardiography in the detection and follow-up of congenital pulmonary arteriovenous malformations.
Pulmonary arteriovenous (A-V) malformation is frequently a manifestation of Osler-Weber-Rendu syndrome (hereditary hemorrhagic telangiectasia). We identified 14 patients (9 men and 5 women) with A-V malformation by contrast echocardiography; 10 patients with atrial right-to-left shunt served as control subjects. Agitated saline solution (10 ml) was injected through a peripheral vein during echo...
