Left ventricular chamber quantification by real time 3D echocardiography

Indian Heart Journal 2011, 63 (5): 429-33
Accurate assessment of left ventricular (LV) function, LV volume, ejection fraction and segmental wall motion abnormalities is essential for clinical decision-making and follow-up assessment. Currently, two-dimensional echocardiography is the most widely used method to obtain this information. Three-dimensional echocardiography has shown to be an accurate and reproducible method for LV quantitation. In this review, we describe various methods to acquire a 3D-dataset for LV volume and wall motion analysis, including their advantages and limitations. We provide an overview of studies comparing LV volume and function measurement by various gated and realtime 3D echocardiography methods of acquisition compared to magnetic resonance imaging. New technical advances like online assessment and single beat acquisition of data have minimized the errors in assessment of LV function.
