Ventricular Septal Defect (VSD) Closure

What is a ventricular septal defect (VSD)?

A congenital defect occurring in the ventricular septum, the wall separating the lower chambers of the heart known as ventricles, is known as the ventricular septal defect. As a result oxygen-rich red blood passes from the left ventricle, through the opening in the septum, and then mixes with oxygen-poor blue blood in the right ventricle. If not treated, this can lead to lung disease due to a larger volume of blood passing from the right ventricle through the pulmonary artery into the lungs, thereby causing higher pressure than normal in the blood vessels in the lungs.

How is the procedure done?

  • The paient is adminsitered general anaesthesia and is connected to monitoring devices
  • A median sternotomy incision that begins at or below the top of the breastbone and goes straight down the sternum (breastbone) is made and the breastbone separated to expose the heart.
  • The patient is then placed on the heart-lung bypass machine, a device that provides blood flow to the body and “bypasses” the patient’s heart and lungs. D
  • Depending on the location of the defect, an incision will be made in either the right atrium, the pulmonary artery, or the outflow tract of the right ventricle.
  • A patch is created by the surgeon from either the patient’s own pericardial tissue or a synthetic material such as Dacron.
  • The patch is then sutured into place to close the defect.
  • The atrial, pulmonary artery or infundibular incision is then closed with sutures.
  • The patient will be weaned gradually off of the heart-lung bypass machine until the newly repaired heart is managing all the blood flow again. 
  • Chest tubes will then be placed to drain the surgical area. The sternal bone is brought together, and stainless steel wire secures the sternum. 
  • The breast bone is sewn back with wires and all incisions are closed.
