Atrial septal defect is a type of congenital heart disease that does not usually affect fertility. This is because atrial septal defect is a heart disease, while in terms of fertility, it is a disease of the uterus, ovaries, and fallopian tubes. The treatment of atrial septal defects is divided into minimally invasive interventional blocking treatment and surgical open-heart direct repair treatment, both of which are capable of achieving a radical cure. After the surgery, the patient needs to take cardiotonic, diuretic and myocardial drugs for a long time, so that the patient can recover from the heart function as soon as possible. It is also necessary to pay attention to a reasonable diet and a regular lifestyle in order to restore the patient to a healthy state as soon as possible.
