摘　　要：本文应用多巴酚丁胺负荷三维超声心动图研究法洛氏四联症(TOF)根治术前左心室舒张末期容积(LVVd),收缩末期容积(LVVs)、射血分数(LVEF).研究对象:患儿组25例(男14、女11),年龄1.00～11.50(4.50士2.69)岁;对照组8例(男6、女2),年龄1.29～14.83(8.39土4.14)岁.结果:TOF根治术前左心室舒张末期容积指数(LVEDVI)小于正常,静息状态LVEF正常;多巴酚丁胺负荷试验(DST)中,LVVd最大增大率、LVVs最大缩小率、LVEF最大增高率TOF组明显低于正常.结论:TOF根治术前左心室发育不良,静息状态射血功能正常,DST揭示出TOF根治术前潜在的左心功能贮备减低.Three-dimensional dobutamine stress echocardiography was employed to evaluate the left ventricular end-diastolic volume (LVVd), end-systolic volume ( LVVs), ejection fraction (LVEF) before total correction of Tetralogy of Fallot (TOF). 25 patients (14 male, 11 female) aged 1.00-11. 50 (4. 50±2. 69) years, and 8 normal controls (6 male, 2 female) aged 1.29-14. 83 (8. 39±4.14) years were examined in this study. Results showed diminished LVVd, but normal LVEF at rest in TOF; during step-wise dobutamine infusion, the maximal changings of LVVd, LVVs, LVEF were smaller in TOF than that in controls, which revealed poor left ventricular cardiac reserve before total correction of TOF.
