This paper examines the evidence for contrast echocardiography, both for improving assessment of left ventricular structure and function compared with unenhanced echocardiography and for the identification of myocardial perfusion. Based on the evidence, recommendations are proposed for the clinical use of contrast echocardiography.

background : hepatopulmonary syndrome (hps) refers to arterial hypoxemia caused by pulmonary vasodilation, which is a consequence of portal hypertension. hps is associated with increased morbidity and mortality; thus, it is important to diagnose this entity as soon as possible for treatment to be administered. materials and methods: in a cross-sectional study, 40 children (6 months to 14 years ...

AIMS To assess the agreement of left ventricular ejection fraction (LVEF) determinations from unenhanced echocardiography, contrast-enhanced echocardiography, magnetic resonance imaging (MRI), and cineventriculography as well as the inter-observer agreement for each method. METHODS AND RESULTS In 120 patients, with evenly distributed EF-groups (> 55, 35-55, < 35%), cineventriculography, unenh...

Myocardial contrast echocardiography is a new method for evaluating myocardial perfusion. However, it relies on the marriage of two evolving technologies; ultrasound contrast agents and ultrasound imaging instrumentation. To date, these technologies have only been available to a limited number of researchers throughout the world. Within the next 12 months, both agents and specialised ultrasound...

Patent foramen ovale (PFO) is a potential separation between the septum, primum and septum secundum located in anterosuperior portion of atrial septum. PFO one main factors causing cryptogenic stroke which fifth leading cause death United States. For diagnosis, contrast transthoracic echocardiography (cTTE) preferred as being more robust method compared with others. However, current diagnosis t...

OBJECTIVE The objective of this report is to assess the ability of microbubble contrast agents to enhance the visualization of cardiac structures in patients with suboptimal echocardiography results. CONTRAST ECHOCARDIOGRAPHY: The most common use of contrast echocardiography is the enhancement of the endocardial border. Left ventricular (LV) opacification with contrast echocardiography has the...
