Ventricular septal defect and atrial septal defect are common congenital heart diseases. If not treated early, these diseases can lead to many dangerous, life-threatening complications. Currently, the most commonly used treatment method for these two diseases is occlusion of the ventricular septal defect and atrial septal defect.

An atrial septal defect is a congenital heart defect that creates a hole in the wall between the right and left atria. Small holes that do not cause symptoms may not require treatment. However, large holes require immediate treatment.
