Device closure

An alternative to surgical closure of atrial septal defect (ASD) is the use of specially made devices to close the ASD. These devices are implanted using special delivery system through a catheter during cardiac catheterization. This is considered a less invasive method than open heart surgery.

  1. The treatment options depend on the age of the person.

  2. In a premature baby, the PDA may close with time, as the baby grows. Some babies may need medications such as  indomethacin, to facilitate closure. Surgery may be needed if the duct fails to close.

  3. In full-term babies, a small defect can be monitored, as it may close with time. Large defects may need to be closed surgically.

  4. Surgical closures can be achieved through open-heart surgery and percutaneous catheterization.

The larger PDA results in increased workload of heart, and also carries a risk of bacterial infection. PDA can be closed by inserting a device through the blood vessel in groin, a non-surgical method called percutaneous transcatheter approach.

VSD device closure is an opening in the wall (septum) dividing the two lower chambers of the heart (ventricles). Normally, this wall closes before birth. The lower two chambers of the heart are called Ventricles. These are separated by a membrane, called the Ventricular Septum, which prevents the leakage of the oxygenated blood from the left ventricle to the right ventricle containing deoxygenated blood.
