Objective To investigate the clinical application value of real-time three-dimensional echocardiography(RT-3DE)in the evaluation of right ventricular remodeling after correction of Ebstein anomaly(EA).Methods A total of EA patients who underwent surgical anatomical correction in our hospital were selected,according to the Carpentier classification,they were divided into type A-B group(10 cases),type C group(6 cases)and type D group(6 cases).The differences of RT-3DE and cardiac magnetic resonance(CMR)findings among groups before operation and 6 months after operation were compared.Pearson correlation analysis was used to analyze the relationship between right ventricular diastolic end volume index(RVEDVi)and right ventricular ejection fraction(RVEF)measured by RT-3DE and CMR.Results RT-3DE show that there were statistically significant differences in left ventricular ejection fraction(LVEF)and RVEF before operation and RVEF at 6 months after operation among groups(all P<0.05).Compared with the preoperative results,the degree of tricuspid regurgitation,RVEF and RVEDVi were decreased in 22 EA patients 6 months after operation,and the differences were statistically significant(all P<0.05).CMR showed that the RVEDVi was decreased in 22 EA patients 6 months after operation compared with the preoperative results,there was statistically significant difference(P<0.05).The correlation analysis showed that the RT-3DE value of preoperative RVEDVi was highly positively correlated with the CMR value(r=0.908,P=0.012),but there was no correlation between the two methods of postoperative RVEDVi(r=0.522,P=0.184),the RT-3DE value of preoperative and postoperative RVEF were highly and moderately positively correlated with the CMR value(r=0.818,0.564,both P<0.05).Conclusion RT-3DE could accurately evaluate the right ventricular volume and function in EA patients,and has important clinical application value in the evaluation of postoperative right ventricular remodeling.
