Atrial septal defect

Atrial septal defect (ASD) refers to a condition where a portion of the septum between the right and left atria of the heart fails to close completely during fetal development. ASD accounts for approximately 10% of all congenital heart diseases, ranking as the second most common congenital heart disease in children. It accounts for 20% to 30% of congenital heart diseases in adults, making it the most common congenital heart disease in adults. It is more prevalent in females than males. Common Questions Q: Does atrial septal defect affect pregnancy? A: The impact of atrial septal defect on pregnancy varies depending on the specific condition of the pregnant woman. Although cardiac load increases during pregnancy, young pregnant women with simple defects can tolerate pregnancy, even multiple pregnancies, without significant adverse outcomes. However, if there is a history of certain arrhythmias or heart failure, the risk of pregnancy increases, requiring close monitoring. There is a higher risk of specific venous embolisms and abnormal blood shunting during delivery compared to the general population. If there is coexisting significant pulmonary vascular disease, the risk of maternal and fetal mortality is high, and pregnancy should be avoided in such cases.
