先天性心脏病是在出生时发现的最常见的畸形。在无高危因素的活胎中,先天性心脏病的发生率是0.86%,若把死胎和自然流产计算在内,其发生率可能还要升高。在出生时诊断出的心脏病,大约50%有较大的或复杂的异常,其中一些人几乎不能用当前最先进的心脏手术进行治疗。因此,胎儿超声心动图在妊娠筛选、分娩处理和产后检查中均有重要的作用。为了评估在无高危因素人群中的胎儿超声心动图筛选的临床意义,作者观察了意大利Trieste地 Congenital heart disease is the most common deformity found at birth. The incidence of congenital heart disease in live births without risk factors is 0.86%, and the incidence of stillbirth and spontaneous abortion may increase. About 50% of those diagnosed at birth have larger or more complex abnormalities, and some of them are barely treatable with current state-of-the-art cardiac surgery. Therefore, fetal echocardiography in pregnancy screening, childbirth and postpartum examination have an important role. In order to assess the clinical significance of fetal echocardiography screening in non-at-risk populations, the authors looked at the geographical distribution of Trieste, Italy
