摘　　要：目的应用三维超声心动图(3-DE)初步评价房间隔缺损(ASD)面积变化率的临床意义。方法应用三维超声心动图测量ASD最大面积和最小面积,并由此计算出面积变化率;同时应用三维超声进行左右心室容积及心功能测量,观察各指标间有无关系。结果三维超声心动图能精确进行ASD面积测量,ASD面积变化率与RVEDV和RVEF分别呈中度正相关和中度负相关,ASD最大面积与最小面积存在高度相关性。结论面积变化率的测量有助于评估ASD患者右心室功能,并可全面掌握ASD大小,有利于临床医生进行ASD封堵或手术。Objective Three dimensional echocardiography （3-DE） was applied to measure ASD area change percentage. Methods The maximum and minimum ASD areas were measured by 3-DE and the percentage change in the defected area was calculated. Then, the capacities and the functions of both ventricles were measured and the correlation between area change percentage and ventricular function indices were observed. Results 3-DE could precisely measure the ASD. ASD area change percentage correlated with RVEDV and 3-DE had negative correlation with RVEF. The maximum area correlated well with the minimum area. Conclusions The measurement of area change percentage is helpful to learn the RV function in ASD patients and the size of ASD which was beneficial to ASD occlusion or operation.
