A Ventricular septal defect is a birth defect of the heart in which there is a hole in the wall (septum) that separates the two lower chambers (ventricles) of the heart. This wall also is called the ventricular septum.
In Open Heart Surgery for VSD, the hole in the heart is closed by making a tiny hole through the chest, inserting an endoscope the hole is closed with sutures and special tissue patch. Surgery is chosen for heart holes which are bigger in size. The defect may be closed with stitches or a special patch.
In Device Closure technique cardiac catheterization is used to put a special device (septal occluder) in the open. The device stops blood from flowing through the VSD. A catheter is inserted through the groin and the device is inserted through the catheter and is left over the hole to close it. This procedure is chosen for small sized holes.
