Device closure for congenital septal defects is being performed for over 40 years. It is the most considered first-in-line procedure over surgical closure. Device closures are used to close a defect or abnormal openings in the heart. Some of these openings are present at the time of birth called congenital heart defects. They are mostly located in the walls (septum) of heart between the upper chambers (arteries) and lower chamber (ventricle) of the heart.
What is Device Closure?
Device Closure is an alternative to surgical closure of septal defects like ventricular septal defect (VSD) or atrial septal defect (ASD) by using specially made devices. These devices are implanted in the heart through special delivery system using a catheter during the procedure of cardiac catheterization. This is a less invasive approach for septal defects than open-heart surgery.
How is Device Closure Implanted?
- The whole procedure is performed in the Angiography Suite when the patient is under general anaesthesia.
- A device is folded and attached to a special catheter(narrow plastic tube) and inserted into a vein through the arm or groin area to reach the defect.
- The device attached to the catheter is slowly pushed out to cover each side of the hole closing the defect.
- When the device is in the exact position, it is released from the catheter which expands and cover the hole.
- Later the heart tissue is grown over the implant and becomes a part of the heart.
- The whole procedure is monitored by X-ray and an ultrasound camera which is attached to the catheter and inserted from a vein to the heart.
What Are The Advantages Of Device Closures?
- Cardiopulmonary bypass or cardioplegia is not necessary.
- There will be no surgical scars.
- Minimal pain compared to open surgery.
- Shorter hospital stay.
- Fastest recovery
Of course, not all ASDs and VSDs are suitable for device closure procedures. The doctor will perform the necessary diagnosis and decide whether a person is ideal for the procedure or not. There were different closure devices available for closing septal defects.
