Surgeons will be performing a surgery known as the Glenn, the second of three surgeries JJ will have to have to restore function to his heart. The Glenn involves disconnecting the superior vena cava from the heart and sewing it into the right pulmonary artery. Surgeons also will have to repair his aorta by adding a new smaller patch in a separate procedure that will be performed at the same time as the Glenn.
