Measurements obtained were significantly different between those venders, and hence, may not be used interchangeably. Normal left ventricular indices obtained from 3-dimensional echocardiography datasets were established, using Philips QLAB and TomTec 4D LV ANALYSIS software. Mean indexed left ventricular diastolic, and systolic volumes measured with QLAB were significantly higher as compared to TomTec with insignificant difference in the ejection fraction. Mean left ventricular diastolic, and systolic volumes indexed to body surface area and ejection fraction were: 24.7 ± 3.6 ml/m 2, 9.2 ± 1.3 ml/m 2 and 62 ± 3.8% using TomTec and 26.6 ± 3.8 ml/m 2, 10.4 ± 2 ml/m 2 and 63 ± 3.1% using QLAB, respectively. Left ventricular dimensions, volumes and ejection fraction were measured using Philips QLAB version 9.0 and results were compared to results of the same datasets, analysed using TomTec 4D LV software. 38 babies underwent full Echocardiographic evaluation, including the acquisition of several 3-dimensional datasets, while naturally sleeping. Fifty consecutive newborns or neonates coming to their first newborn visit within the first 3 weeks of live, were recruited. The aim of this study was to compare left ventricular dimensions and ejection fraction obtained from the same 3-dimensional echocardiography datasets using 2 commercially available applications: Philips QLAB and Tomtec 4D LEFT VENTRICLE-ANALYSIS. The validity and normal values have been established in a large group of normal adults, children and neonates.
