Surgical repair of ventricular defects requires extracorporeal circulation and a positive surgical outcome. If the child is in good condition before surgery, the postoperative recovery is rapid. Usually, the child can return to the ward from the postoperative recovery room (ICU) on the second day after surgery, and can be discharged from the hospital in 7 days, taking some oral medications home for about a month. The vast majority of children with heart murmurs disappear after surgery, and the structure and function of the heart are restored as normal. Some children with poor preoperative health, severe pulmonary hypertension, recurrent respiratory infections, or severe cases of young age and low weight will have a longer recovery time after surgery. However, once fully recovered, such children will have a very significant improvement. There are generally no postoperative sequelae after ventricular defect surgery. Children who undergo interventional closure of ventricular defects are often older (over 3 or 4 years old), and if the closure is successful, they can be discharged 2 to 3 days after surgery, with the heart murmur disappearing and the heart structure and function as normal, usually without sequelae.
