Abstract:
Objective To explore the correlations of evaluations of right heart function parameters in patients with Ebstein anomaly(EA)using echocardiography and cardiac MRI.Methods Data of transthoracic echocardiography and cardiac MRI in 32 patients with EA confirmed by operation were retrospectively analyzed.The correlations of cardiac cavity size,right ventricular function and strain parameters obtained using echocardiography and the functional right ventricular(fRV)ejection fraction(EF)measured using MRI were explored.Results MRI fRV-EF in 32 cases of EA was(23.20± 7.61)％.Among echocardiographic parameters in 32 cases of EA,fractional area change(FAC)of fRV(r=0.347,P=0.015)was slightly,while global longitudinal strain(GLS)of fRV(r=0.801,P＜0.001)was highly positively correlated with MRI fRV-EF,respectively,whereas atrialized right ventricle(aRV)area/fRV area(r=-0.730,P=0.007)was highly negatively,aRV area/left ventricular area(r=-0.450,P=0.042)and right ventricular anterior-posterior diameter(r=-0.650,P=0.022)were both moderately negatively correlated with MRI fRV-EF.Both the left ventricular eccentricity index(r=-0.347,P=0.049)and Glasgow outcome scale extended(r=-0.336,P=0.024)obtained with echocardiography were slightly negatively correlated MRI fRV-EF.Conclusion Right heart function parameters in EA patients obtained with echocardiography were correlated with those of MRI fRV-GLS,among which aRV area/fRV area were highly positively correlated with MRI fRV-EF,hence having great value for evaluating right heart function in EA patients.
