摘　　要：目的：评价ASD患者术前及术后不同时间右心室容量及收缩功能。方法使用实时三维超声心动图（RT-3DE）对30例单纯继发孔型房间隔缺损患者术前及术后不同时期（7 d至6个月）测量右心室舒张末期容积（RVEDV）、收缩末期容积（RVESV）、右心室射血分数（RVEF），对比上述参数分析右心室收缩功能。结果术后7 d右心室RVEDV、RVESV略降低、RVEF略升高，但与术前无显著差异（ P＞0.05），术后3～6个月，RVEDV、RVESV及RVEF较术前明显增高（ P＜0.01）。结论 RT-3 DE可较好评价继发孔型房间隔缺损患者手术后右心室收缩功能。Objective To evaluate right ventricular ( RV) morphology and systolic function before and after different times in the patients with atrial septal defect ( ASD) by real-time three dimensional echocardiography ( RT-3DE).Methods RT-3DE was applied to measure right ventricular end diatolic volume (RVEDV),end systolic volume(RVESV)and ejection fraction(RVEF)before and after operation,7 d,1 month,3 months and 6 months, these parameters were compared to analyse right ventricular systolic function .Results RVEDV,RVESV and RVEF decreased slightly 7 d after operation ,and RVEF increased slightly too ,while those showed no significant difference ( P>0.05 ) .RVEDV and RVESV decreased obviously , while RVEF increased significantly from 3 months to 6 months after operation ( P<0.01 ) .Conclusions Real-time dimensional could be better estimated right ventricular systolic function of ASD patients after operation .
