Abstract
Echocardiography has an important role in the diagnosis, treatment, and management of patients who require transcatheter valvular interventions. Left ventricular ejection fraction (LVEF) is a very popular parameter for the assessment of LV function. Although several cut-off values of LVEF have been used for decision making in patients with valvular heart disease, less attention has been paid to its accuracy and reliability. Observer variability is a significant concern, and >10% differences in LVEF measurements between two sonographers could occur in the same two-dimensional echocardiography datasets. The adoption of fully automated LV quantification software with three-dimensional echocardiography (3DE) might be one potential solution to eliminate this problem. We will review the current status of fully automated software with 3DE for the assessment of LV volumes and LVEF.
