【摘要】 目的评价ASD患者术前及术后不同时间有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-3DE可较好评价继发孔型房间隔缺损患者手术后有心室收缩功能。更多还原

【Abstract】 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,l 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 6months after operation(P <0.01).Conclusions Real-time dimensional could be better estimated right ventricular systolic function of ASD patients after operation.更多还原
