Abstract：Objective To explore the feasibility of real-time three-dimensional echocardiography in mitral stenosis .Methods Twenty-three healthy volunteers were included as control group .The mitral stenosis group consisted of 21 patients.They were di-vided into two groups:2D group and RT-3DE group.Mitral valve orifice area (MVA) was calculated.Receiver-operating charac-teristic ( ROC) courve was drawn to assess the diagnostic efficiency .Interobserver agreement for MVA was calculated using the Kappa statistic .Results There were significant differences of the MVA between patient group and volunteer group ( P <0.001).The area under the curve (AUC) of MVA indicated that 2D was higher than RT-3DE in diagnosis of mitral stenosis (AUC>0.8).No significant difference of diagnostic value was found between 2D and RT-3DE ( P >0.05).Interobserver a-greement was good ( k =0.789, 0.777, 0.787, 0.786).Conclusion RT-3DE showed its feasibility in mitral stenosis evalua-tion.It could be used to assess the MVA and may be a supplement method for clinical diagnostics .
