Three-dimensional echocardiography in evaluation of left ventricular systolic function after mitral valve replacement for chronic mitral diseases with preservation of mitral apparatus



Three-dimensional echocardiography in evaluation of left ventricular systolic function after mitral valve replacement for chronic mitral diseases with preservation of mitral apparatus



Zhonghua Yi Xue Za Zhi 76(7): 516-518



To assess the global left ventricular performance in 24 normal subjects, 24 patients suffered from mitral valve disease (MVD) with mitral valve replacement (MVR), and 20 patients with mitral valve replacement with preservation of mitral apparatus (MVRP). 3DE was used in comparion with the findings of radiography (RNA), two-dimensional echocardiography (2DE), and m-mode (MME). EF in 10 patients with MVD as compared with RNA, 3DE showed a higher connection coefficient than 2DE and MME. The EF estimated by MME and 2DE showed no difference between NS and MVD groups, there were significant differences when compared with those examined by 3DE. Two, three months after opertion, the VED and VES in group of MVRP were significantly lower than those in group of MVR (P < 0.01), the EF of MVRP group was remarkably higher than that of MVR group (P < 0.05). 3DE has the ability to estimate the EF of left ventricle more accurately than 2DE and MMe, especially in the patients suffered from chronic MVD with LV shape deformation. The MVR with preservation of mitral apparatus for chronic MVD is beneficial to maintaining the global systolic function after surgery.
