| 摘 要： | 用桡动脉搏动图、心脏收缩间期、B型超声心动图和选择性心血管造影测定20例法乐四联症患儿的左心功能。结果:法四患儿CI,EF及LEDV/REDV明显低于同龄正常儿童,a波时间和LPEP/LVET明显高于同龄正常儿童。表明法四患儿左心功能明显降低,CI与升主动脉内径/主肺动脉内径值呈直线负相关,r=-0.8237。因此,升主动脉内径/主肺动脉内径值可作为评价法四患儿左心功能、预测手术效果的主要指标。

| Abstract: | The prognosis and result of operation of TOF is based onthe left ventricular function(LVF),20 cases of TOF were diagnosed accord-ing to cineoangiography,16 cases were operated.LVF were determined bysystolic time interval 2-D echoeardiography and radial pulsegraphy.Cardiacindex(CI),EF,LEDV/REDV were significantly lower than normal.Awave time and LPEP/LVET were significantly higher than normal.It meansLVF was significantly low in TOF.CI was close related to the ratio ofdiameter of ascending aorta to diameter of main pulmonary artery,r=-0.8237.According to our experience,if the ratio is less than 2,operationwill be sere,if the ratio is 2-3,the patient can be operated,butit is dangerous.If the ratio is larger than 3,radical operation should beavoided,it would be better to choose palliative operation. |
