胎儿超声波检查在孕期12周即能对某些先天性心脏畸形作出诊断,如在20周时进行畸形纠正可以中止畸形向复杂转化、简化手术方法、增强疗效、避免胎儿夭折与生后复杂的心脏手术以及巨大的手术风险。成熟的体外循环支持技术是进行胎儿心脏手术成功的关键。从上世纪90年代起,Champsaur、Hanl- ley、Sakata等已预见了胎儿心脏外科时 Fetal ultrasound can diagnose some congenital heart malformations at 12 weeks of pregnancy. If the deformity is corrected at 20 weeks, it can stop the deformity to complex transformation, simplify the operation method, enhance the curative effect, and avoid the premature death and the complex heart after birth Surgery and great surgical risk. Mature cardiopulmonary bypass support technology is the key to successful fetal heart surgery. From the 90s of last century, Champsaur, Hanlly, Sakata, etc. have foreseen fetal cardiac surgery
