Left atrial hypertrophy in pregnancy generally has no effect if the cardiac function is good, and it is recommended that assessment be made before pregnancy and regular checkups be done during pregnancy.

However, it should be noted that if you are over 35 years of age and have other serious and complex heart disease in addition to left atrial hypertrophy, the risk of pregnancy may increase significantly, which not only has a higher maternal mortality rate, but also increases the risk of serious maternal and child complications, so pregnancy is not recommended. It is recommended that people with left atrial hypertrophy need to be actively examined and evaluated before or during pregnancy, and to seek timely and standardized diagnosis and treatment.
