Atrial septal defect surgery is also known as atrial septal defect occlusion, generally atrial septal defect occlusion can be the same as normal after surgery. If the atrial septal defect is combined with severe pulmonary hypertension, the pulmonary artery pressure may not always return to normal after surgery, which may have a certain effect on heart function. Atrial septal defect occlusion can relieve the symptoms caused by atrial septal defects, but also improve heart function, if there is no problem with heart function and other aspects of the heart before the operation, it can be exactly the same as normal people. There will not be a big difference, but it is important to be careful not to do sports such as high jumping, bungee jumping, long-distance running and other sports that cause the heart to beat violently. Atrial septal defect blocking surgery is to place the blocking material in the atrium through venous puncture to block the atrial septal defect, so that the blood circulation in the atrium can be normalized, and the damage of this surgery is relatively small and the success rate is also relatively high. After the surgery, a proper diet is needed and regular checkups are performed. Observe the recovery of the body after the operation. Patients with atrial septal defects need to be treated in a timely manner to prevent the development of the disease from affecting the function of the heart.
