[Total isolated anomalous pulmonary venous return: Are there any clues for prenatal screening?].

Total anomalous pulmonary venous connection (TAPVC) is a serious congenital anomaly. TAPVC with obstruction of pulmonary venous return is an emergency requiring urgent intervention. Before 2010, very few isolated TAPVC were diagnosed prenatally. It has been suggested in the past literature that the use of Color flow Doppler is particularly useful for the screening of TAPVC prenatally. In fact, although color-Doppler is often useful to confirm a TAPVC diagnosis, it can be quite misleading in the screening process of the condition. Looking at data of missed TAPVC, we describe how to identify TAPVC during routine cardiac screening. Since 2010, our isolated TAPVC prenatal diagnosis rate is more than 40%.
