先天性心血管疾病是胎儿时期心血管结构、心脏传导系统及心脏功能发育异常所导致的先天性心脏疾患,包括先天性心血管畸形(先天性心脏病CHD)、心律失常、心脏肿瘤、心肌疾病等。先天性心脏病(CHD)是最常见的出生缺陷,在欧洲国家中,先天性畸形的发病率为23.9/1000活产婴儿,心脏畸形在非染色体异常中最常见,占6.5/1000活产婴儿。胎儿CHD中约1/2为严重心血管畸形,在围生期因先天性畸形死亡的婴儿中约占40%。20%～30%心脏缺陷胎儿在
Congenital cardiovascular disease is a congenital heart disease caused by fetal cardiovascular structure, cardiac conduction system and cardiac dysfunction in the fetal period, including congenital cardiovascular malformations (CHD), arrhythmia, cardiac tumors, myocardial diseases Wait. Congenital heart disease (CHD) is the most common birth defect. In European countries, the incidence of congenital malformations is 23.9 per 1,000 live births. Heart malformations are the most common in non-chromosomal abnormalities, accounting for 6.5 / 1000 live births . About one-half of fetal CHD is a severe cardiovascular malformation, accounting for about 40% of infants who have died of congenital malformations during the perinatal period. 20% to 30% of fetal heart defects in the fetus
