Abstract:
Objective To evaluate the clinical value of real-time 3 dimensional echocardiography (RT-3DE) for measurement of right ventricular function in the repaired tetralogy of Fallot (TOF) compared to cine magnetic resonance imaging (c-MRI).Methods Thirty-seven randomly selected patients with repaired TOF from Jan.2000 to Jun.2007 in Children's Hospital,Fudan University underwent both RT-3DE and c-MRI for the data of right ventricular enddiastolic volume (RVEDV),right ventricular end-systolic volume (RVESV),right ventricular ejection fraction (RVEF),which were compared to evaluate the reproducibility and correlation of two ways on right ventricular function.Results All the patients completed both RT-3DE and c-MRI on the same day.The correlation for RVEDV,RVESV,RVEF measured by 2 methods was high (r =0.933,0.943,0.911,P =0.000,0.000,0.105),and it showed that consistency existed in RVEF,as difference was only (1.2 ± 4.5) ％.Comparison with c-MRI,RVEDV and RVESV measured by RT-3DE was underestimated,in which difference was (-17.4 ± 16.9) mL,(-9.3 ± 10.5) mL.Conclusions RVEF with RT-3DE can be assessed with acceptable accuracy,but it is not so good for RVEDV and RVESV.Further study needs to be performed to make sure the value of RT-3DE on the assessment of right ventricular function in repaired TOF.
