1987年3月至1989年8月,328例先天性心脏病患者在体外循环前后常规应用超声心动图和彩色多普勒血流图象(Echo-DCFI)检查。术前所有病人均经胸壁行 Echo-DCFI 检查。271例(83％)接受心导管检查,其中52例受检距手术时间超过三个月。病人年龄从1天到59岁,平均5.9岁。最小的病人体重仅1.8kg。术中检查一次时间为3.6±1.7分钟。经心外膜途径获得的图象质量优于经胸壁途径。体外循环前检查,发现60例(18％)病人有原先未被认识到的解剖情况,如房缺、多发 March 1987 to August 1989, 328 patients with congenital heart disease before and after cardiopulmonary bypass routine use of echocardiography and color Doppler flow imaging (Echo-DCFI) examination. All patients underwent preoperative Echo-DCFI chest wall examination. 271 patients (83%) underwent cardiac catheterization, of which 52 had an inspec- tation of more than three months. The patient’s age ranged from 1 day to 59 years with an average of 5.9 years. The smallest patient weighs only 1.8kg. Intraoperative examination for a time of 3.6 ± 1.7 minutes. The quality of the image obtained via the epicardial route is superior to the transthoracic route. Pre-cardiopulmonary bypass examination found that 60 patients (18%) patients had previously not been aware of the anatomy, such as atrial septal, multiple
