背景：本研究的目的是评价三维（3D）超声与标准磁共振成像方法在确定成人先天性心脏病和慢性严重肺反流（PR）患者右心室（RV）体积和功能方面的准确性。方法：采用三维超声和MRI对25例肺动脉瓣切开术或法洛四联修复后继发的严重PR进行评价。结果：左心室射血分数平均3D超声为42 +/- 8%，MRI为44 +/- 7% （r = 0.89, P < 0.0001）。三维超声和MRI显示舒张末期平均容积分别为249 +/- 66和274 +/- 82 mL，收缩期末期平均容积分别为147 +/- 50和159 +/- 60 mL。同样，3D超声和MRI显示舒张末期容积和收缩末期容积有很强的相关性（r = 0.88和r = 0.89）。结论：三维超声与MRI在确定大多数复杂先天性心脏病患者右心室大小和功能方面具有可比性。在更大的TOF患者群体中研究3D超声非常重要，这只有通过多中心合作才能实现。（中华医学会心脏科杂志，2010;23:127-33）
Background: The aim of this study was to evaluate the accuracy of three-dimensional (3D) ultrasound compared with the standard magnetic resonance imaging method in determining right ventricular (RV) volumes and function in adult patients with congenital heart disease and chronic, severe pulmonary regurgitation (PR).Methods: Twenty-five patients with severe PR secondary to either pulmonary valvotomy or tetralogy of Fallot repair were evaluated using 3D ultrasound and MRI.Results: The mean RV ejection fractions were 42 +/- 8% on 3D ultrasound and 44 +/- 7% on MRI (r = 0.89, P < .0001). The mean end-diastolic volumes were 249 +/- 66 and 274 +/- 82 mL and the mean end-systolic volumes 147 +/- 50 and 159 +/- 60 mL on 3D ultrasound and MRI, respectively. Similarly, there were strong correlations of both end-diastolic volume and end-systolic volume on 3D ultrasound and MRI (r = 0.88 and r = 0.89, respectively).Conclusions: Three-dimensional ultrasound was comparable with MRI in determining RV size and function in most patients with complex congenital heart disease. It will be important to study 3D US in a larger population of patients with TOF, which will be possible only through multi-center collaboration. (J Am Soc Echocardiogr 2010;23:127-33.)
