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,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 .关键词
