| Abstract: | Objective To investigate the feasibility of real-time three-dimensional echocardiography (RT3DE) in analysis of left ventricular regional diastolic function using regional volume-time curves. Methods In thirty-five healthy participants, regional volume-time curves (rVTC) and LV regional diastolic functional parameters were generated by three-dimensional echocardiographic databanks from analysis software of Tom Tec, regressed and compared by statistic software. Results RT3DE and 2DE images, data and dynamic rVTC in all the participants were satisfactory.Conclusion Generation of rVTC by RT3DE is feasible, and rVTC by RT3DE is a promising new approach providing access to quantitative information on LV regional diastolic function. |
