%X Objective To evaluate the accuracy and influence factors during semi-quantization of valve regurgitation by the vena contracta width with the real-time tri-plane echocardiography.Methods The vena contracta width of the regurgitant orifice with the diameter of 2 mm,4 mm,6 mm,8 mm were observed and measured in the condition of different pressure gradient and the value with the real-time tri-plane echocardiography using the self-made valve regurgitation model was obtained.Results The vena contracta width did n...
