Under general anesthesia of tracheal intubation, a median sternotomy was made to establish cardiopulmonary bypass. After blocking the cardiac circulation, cutting the front wall of the outflow tract of the right ventricle can expose various types of ventricular septal defects, but it has certain damage to the myocardium, affecting the function of the right heart and damaging the right bundle branch. At present, right atrial incision is often used to expose membranous defects. For high defect, pulmonary artery approach is suitable. For small defects with fibrous tissue on the edge, they can be directly stitched, and for lcm, they can be repaired with polyester fabric. The conduction beam passes through the lower edge of the membranous defect, which is easy to be accidentally injured when repairing the septal defect. It should be avoided as far as possible, and the seam should be close to the root of the septal flap.

Traditional cardiovascular surgery mostly adopts median sternotomy, and some of them are left posterolateral thoracotomy. With the continuous improvement of the safety of cardiovascular surgery, people pay more and more attention to the beauty of the incision during the operation. In recent years, minimally invasive small incision surgery has gradually been favored by the majority of patients who love beauty. Let's briefly introduce the relevant knowledge.

In short, small incision surgery is characterized by beautiful incision, addiction, less trauma, less bleeding, quick recovery, good healing, less deformity and less cost. However, for patients with complicated conditions, or obese adults with flat chests, we must choose carefully according to the condition and the doctor's advice.
