ABSTRACT
Objective To assess the accuracy and repeatability of real-time three-dimensional eehoeardiography (RT-3DE) for the measurements of left ventricular (LV) mass in elderly patients compared with magnetic resonance imaging (MRI).Methods A total of 31 patients (26 men) aged ≥60 years (72.1±6.6) years with various cardiovascular diseases were evaluated by MRI and RT- 3DE on the same day.RT-3DE was performed with a Philips iE-33 echocardiographic system, and LV mass was analyzed with the assistance of TomTec software.The results of LV mass obtained by manual tracing were compared with Signa 1.5-T MRI data.The acquisition of RT-3DE datasets was feasible in all 31 patients.Results A good correlation was observed between RT-3DE data with manual border detection and MRI for LV mass (r=0.869, y=0.943 x+11.69, SE= 19.09 g, P< 0.01), with a mean difference of (4.7±37.7)g.The average LV mass was (123.9±35.0)g (74.4-208.1 g) evaluated by MRI, and was (128.6±37.9)g (67.0-222.9 g) evaluated by RT-3DE.There was good inter- or intra-observer correlation between RT-3DE by two sonographers for LV mass.Conclusions The assessment of LV mass from RT-3DE data is feasible in elderly patients.The mass can be determined with high accuracy and low interobserver variability in elderly patients with adequate eehocardiographic image quality.
