Our objective was to describe the appearance of atresia of the left-sided atrioventricular valve on the four-chamber view of the fetal heart. Twenty-four cases of atresia of the left-sided atrioventricular connection were detected over a 2-year period. Cases were analyzed according to the appearance of the four-chamber view and the connections of the great arteries. All cases were referred because the left-sided ventricle was smaller than the right. There were five different groups of cardiac anomaly detected. Associated findings varied according to the diagnostic group. It was concluded that it is possible to identify atresia of the left-sided atrioventricular connection accurately during obstetric ultrasound examination by evaluation of the four-chamber view. However, the appearance of this view varies with the diagnosis. Each diagnostic group has different implications in terms of associated extracardiac malformations and postnatal management.
我们的目的是描述胎儿心脏四腔心切面左侧房室瓣闭锁的表现。在两年时间里共检测到24例左侧房室连接闭锁病例。根据四腔心切面的表现和大动脉的连接情况对病例进行分析。所有病例均因左侧心室小于右侧心室而被转诊。共检测到五种不同类型的心脏异常。相关发现因诊断组不同而有所差异。得出的结论是，在产科超声检查中，通过评估四腔心切面能够准确识别左侧房室连接闭锁。然而，该切面的表现会因诊断不同而有所变化。每个诊断组在相关心外畸形和产后管理方面都有不同的意义。
