Post-discharge medication: Most of the cases have been cured by surgery, so there is no need to take medication after discharge from the hospital. For those with poor cardiac function after surgery for complex cardiac malformation, it is still necessary to continue to use medication to support cardiac function, mainly with cardiotonic, diuretic and vasodilator drugs (taken under the guidance of the doctor). Oral hygiene: 3-6 months after surgery is not suitable for treatment of dental caries; if treatment is needed, it should be discussed with cardiologist and prophylactic antibiotic treatment should be carried out before treatment; proper care of teeth is required in daily life, correct brushing and chewing, paying attention to oral hygiene and dental examination every six months. Vaccination: Try not to vaccinate 1 month before and 1 month after the heart surgery; 3 months after the surgery, the general condition is good and routine vaccination can be performed. Marriage and childbirth: If congenital heart disease recovers well after surgery and there are no serious complications and sequelae, most of them can get married and lead a normal sexual life when they reach the marriage age. However, it should be noted that marriage must be done after complete recovery of physical strength and cardiac function and with the consent of the doctor. Most female patients can also get pregnant and have children after marriage, but a few complicated cases should be decided on a case-by-case basis. If the postoperative heart function is poor, pregnancy is not advisable to avoid increasing the burden on the heart.
