Enhancing the Quality of Left Ventricular Ejection Fraction Assessment by Echocardiography

Abstract

IOV in the assessment of LVEF. Galema et al. showed that, in a cohort of patients who had recently undergone primary angioplasty for the treatment of acute myocardial infarction, both intra-observer variability and IOV in the assessment of LVEF were significantly reduced after left ventricular (LV) opacification through the administration of a bolus of contrast agent. 1 Comparison with the mean LVEF results of experienced cardiologists demonstrated that Abstract The assessment of left ventricular ejection fraction is a key clinical investigation guiding the diagnosis, management and prognosis of cardiology patients. Echocardiography is an inexpensive, safe, and portable method commonly used to provide this information. Improvement in the quality of assessment provided by echocardiography continues to be the subject of current clinical programs and investigations. Contrast-enhanced echocardiography is an established method to reduce both inter- and intra-observer variability in the echocardiography lab. The implementation of teaching interventions has also been shown to reduce variability in the qualitative and quantitative assessment of ejection fraction. Newer investigative methods, such as 3D imaging and speckle tracking, show promise as tools to further enhance the quality of left ventricular ejection fraction assessment in the echocardiography lab.
