摘要
采用轴位心血管造影对14个心脏标本行各种角度投照,选择最佳角度准确测量右心室腔容量;并对34例法乐氏四联症(简称四联症)患者进行右心功能测定。结果表明:四联症术前右室功能低于正常,成年组较儿童组明显减低,提示四联症为一种后天进行性加重的先天心脏畸形,应尽早手术矫治。
Cardiac function of patients with congenital heart disease has rarely been studied by axial angiography. The present paper focused on the function of right heart in patients with tetralogy of Fallot by using this method with best angles for evaluation. In order to measure ventricular volumes accurately with axial cineangiography, 14 heart specimens were studied. 70 pictures were taken in various angles during angiocardiography. The right ventricular volume was calculated by Fisher'a prism method. The result demonstrated that the correlation was significant between biplane right ventricular axial views and real ventricular volume(r=0.95, p<0.01). Thirty four cases with tetralogy of Fallot were studied with axial right ventriculography. The results showed that the end-diestolic volume, end-systolic volume, and systolic stroke volume were lower than normal in all cases. The decrease was more significant in adults than that in children. This indicates that cardiacfunction is age-related in tetralogy of Fallot. Myocardial fibrosis and eardiac dysfunction become more marked with increasing age. Therefore, tetralogy of Fallot should be operated early.
