- W2373397997 abstract "Objective To explore the value of assessing stenotic mitral valve orifice area by real-time three-dimensional echocardiography in clinical applications. Methods Twenty-four inpatients with rheumatic mitral stenosis were studied, and all of them were undergone mitral valve replacement surgery. Before the operation, the maximal mitral valve orifice area (MVA) in diastole was recorded by three echocardiographic methods respectively: MVA by two-dimensional echocardiographic planimetry(MVA_ 2DE ), MVA by Doppler pressure half-time method(MVA_ PHT ), and MVA by real-time three-dimensional echocardiographic planimetry (MVA_ RT3DE ). The maximal mitral valve orifice area of mitral specimen(MVA_ OP ) was calculated after the surgery, and it was compared with MVA acquired from above-mentioned echocardiographic methods. Results ①The correlation coefficients of MVA_ RT3DE , MVA_ PHT , MVA_ 2DE and MVA_ OP were 0.85 , 0.78 and 0.74 . ②No statistical difference was found in MVA_ RT3DE , MVA_ PHT , MVA_ 2DE and MVA_ OP ( P 0.05 ). ③Bland-Altman analysis demonstrated that MVA_ RT3DE was well consistent with MVA_ OP . Conclusions RT3DE provides a simple, exact and reliable approach in the quantification of mitral stenosis." @default.
