Description of the Procedure
First, the doctor will cut through the skin and breastbone. The chest cavity will be opened. Next, the heart will be connected to a heart-lung machine. This machine will take over the functions of the heart and lungs. The doctor will stop the heart to do surgery.
The pericardial sac around the heart will be opened. The doctor may remove a small part of this sac and use it to patch the hole. A cut will be made in the right atrium. A small hole will be closed with sutures. A larger hole will be covered with a patch that is made of the sac or other material. Once the defect is repaired, the doctor will close the incision. The heart will then be restarted. Once it is working fine, the heart-lung machine will not be needed. The doctor will close the chest cavity. Sutures will be used to close the skin.
