Objective:To explore application value of three-dimensional (3D) echocardiography in mitral insufficiency (MI). Methods:A total of 180 MI patients who admitted to The Affiliated Hospital of Xuzhou Medical University from January 2023 to November 2023 were selected,and they were divided into a severe group (n=130) and a mild group (n=50) based on the MI severity. Both groups received routine echocardiography and 3D echocardiography to compare the parameters of routine echocardiography,and analyze the diagnostic efficacy of echocardiography for left ventricular configuration and systolic function in MI patients. Results:The heart rate and QRS interval of patients in the severe group were respectively higher than those in the mild group (t=3.910,6.336,P<0.05),respectively. The left ventricular end diastolic diameter (LVEDD),LVEDD index,left ventricular (LV) length,LV length index,left ventricular end diastolic volume (LVEDV),LVEDV index,left ventricular end systolic volume (LVESV),LVESV index,LV mass index (LVMI),relative wall thickness (RWT),and two-dimensional echocardiogram sphericity index (2D-SI) in the severe group were all higher than those in the mild group (t=27.729,14.509,11.745,8.182,24.171,32.989,25.988,20.994,22.707,6.331,20.603,P<0.05). The three-dimensional left ventricular ejection fraction (3D-LVEF) of the severe group was lower than that of the mild group,and the three-dimensional end diastolic velocity (3D-EDV) of blood flow,3D-EDV index,and three-dimensional echocardiogram sphericity index (3D-SI) of the severe group were all higher than those of the mild group (t=2.855,24.320,10.409,36.056,P<0.05). The results of receiver operating characteristic (ROC) curve showed that the sensitivities of LVEDD index,LVEDV index,LVESV index,3D-LVEF,3D-EDV index,and 3D-SI were respectively 70.83％,68.47％,81.25％,71.58％,72.42％ and 90.38％ in diagnosing MI. The specificities of them were respectively 67.40％,65.06％,79.64％,68.10％,71.68％ and 90.38％. The area under curve (AUC) values of the ROC curve were respectively 0.658,0.612,0.814,0.726,0.799 and 0.852. 3D-SI had the highest sensitivity and specificity in diagnosing left ventricular remodeling of MI patients. Conclusion:3D echocardiography has higher application value in MI,which can reflect the remodeling and systolic function of left ventricle. Among of them,3D-SI can better describe the remodeling of left ventricle of patients,and can serve as a reference for the research progress of clinical observation for MI.
