摘    要:目的 用声学定量技术(AQ)评价小儿法乐氏四联症(TOF)根治术前后的左、右室收缩、舒张功能。方法 用AQ测定103名法乐氏四联症患儿根治术前、术后1W、3个月、半年、1年的左、右室心功能参数:舒张末期容积(EDV)、收缩末期容积(ESV)、心室每搏量(SV)、射血分数(EF)、峰值充盈率(PFR)、峰值射血率(PER)和峰值充盈时间(TPFR),将各时期心功能参数进行比较,并与正常组进行对照分析。结果 TOF根治术3个月以后,左心室的收缩、舒张功能已基本恢复正常;右心室的收缩、舒张功能于术后3个月亦逐渐恢复正常,但右心室于术后1年又有逐渐增大的趋势,这与手术切除右心室肥厚肌束的多少、肺动脉瓣返流的多少有关,需密切随诊。结论 AQ技术为定量评价小儿TOF根治术前后的左、右室收缩、舒张功能提供了一种新的方法。

Abstract:Objectives To evaluate systolic and diastolic function of the left and right ventricles before and after the total correction of tetralogy of Fallot(TOF) in children by Acoustic Quantification(AQ). Methods Using AQ, the parameters of left and right ventricle systolic and diastolic function in 103 patients were assaied, at pre-operation; 1 week, 3 months, 6 months and 1 year of the post-operation, respectively, the parameters included end-diastolic volume(EDV), end-systolic volume(ESV),stroke volume(SV), ejection fraction(EF), peak filling rate(PFR), peak ejection rate(PER) and time to peak filling rate(TPFR). We compared the parameters of each groups and contrasted them with the normal groups. Results Three months after the total correction of TOF, the systolic and diastolic function of left ventricle had recovered on the whole, systolic and diastolic function of right ventricle had also recovered gradually. But the right ventricle had a tendency of gradual enlargement one year later. It was concerned with how much the thickening muscles of right ventricle were cut and how much was the pulmonary regurgitation. Close follow-ups were needed after the operation. Conclusions AQ may be used as a new method to evaluate the systolic and diastolic function of left and right ventricles before and after the total correction of TOF in children.
