摘　　要：目的分析超声心动图与心脏MRI所获埃布斯坦畸形(EA)患者右心功能参数的相关性。方法回顾性分析经手术证实的32例EA患者的经胸超声心动图及心脏MRI资料,观察超声心动图所获心腔大小、右心功能及应变参数与MRI所测功能右心室(fRV)射血分数(EF)的相关性。结果MRI所测32例EA的fRV-EF为(23.20±7.61)%。超声心动图所获32例EA右心功能参数中,fRV面积变化分数(fRV-FAC)(r=0.347,P=0.015)与MRI fRV-EF呈低度、fRV整体纵向应变(GLS)(r=0.801,P<0.001)与MRI fRV-EF呈高度正相关,房化右心室(aRV)面积/fRV面积与MRI fRV-EF呈高度负相关(r=-0.730,P=0.007),aRV面积/左心室面积(r=-0.450,P=0.042)及右心室前后径(r=-0.650,P=0.022)与MRI fRV-EF均呈中度负相关,左心室偏心指数(r=-0.347,P=0.049)、扩展格拉斯哥预后评分(r=-0.336,P=0.024)均与MRI fRV-EF呈低度负相关。结论超声心动图与MRI所获EA患者右心功能参数存在相关性;其中,fRV GLS及aRV面积/fRV面积均与MRI fRV-EF呈高度正相关,对于评估EA患者右心功能具有重要价值。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.
