Cardiac repair surgery usually refers to ventricular septal defect repair or atrial septal defect repair, and the surgical methods include intracardiac visualization surgery and interventional occlusion surgery. 1. Intracardiac direct vision surgery: it refers to establishing extracorporeal circulation through the median sternal incision, selecting the right atrium, right ventricle or pulmonary artery incision according to the location of the defect to reveal the location of the defect, and the defect can be sutured directly in the case of small defects, and the defect can be patched with autologous pericardium or artificial patch material in the case of big defects, which is suitable for medium and large defects or those with serious complications. 2. Interventional occlusion: under the guidance of X-ray, the occluder is placed in the heart defect, which is one of the minimally invasive methods to gradually replace the surgical open-heart surgery, with the advantages of small trauma and short postoperative recovery time, and it is suitable for patients with suitable size and location of septal defects. Patients with congenital heart disease who have ventricular septal defects or atrial septal defects, resulting in the flow of blood from the right and left chambers of the heart to each other through the defects (generally left-to-right shunt), resulting in oxygen deprivation and insufficient blood supply to the patient, need to undergo a timely defect repair surgery. If you experience any discomfort after cardiac surgery, please go to the hospital promptly to avoid any delay in your condition.
