Sonovue improves endocardial border detection and variability in assessing wall motion score and ejection fraction during stress echocardiography

摘要

Background Stress echocardiography is useful for assessing patients with coronary artery disease unable to undergo formal exercise testing. Considerable skill is required to avoid large intra- and inter-observer variability due to poor endocardial definition. Intravenous ultrasound contrast agents are now available which may improve this variability.
