Description of the Procedure
Your child will receive IV fluid and medicines through a vein in his arm. The catheter (small tube) will be inserted either in the arm or groin. Next, electrodes will be placed on the chest. These electrodes will send information to the EKG machine, allowing the doctor to monitor the heart.
A catheter will be inserted in the blood vessel and advanced so the end is in the heart. Dye will be injected to allow the doctor to view x-ray images of the heart. An echocardiogram may also be used. Before the hole can be covered, the doctor will need to find out the size of the hole. A catheter with a balloon attached to it will be sent to the upper chambers of the heart. The balloon will inflate and measure the hole.
Once the doctor knows the size of the defect, another catheter will be sent to the heart. This catheter will have a device attached. There are different types of devices available. Some are able to open so that the hole is covered on both sides. Other devices open like an umbrella to cover the defect. Once the device is placed, the doctor will remove the catheter. Lastly, a bandage will be placed over the insertion site.
