How does a Glenn shunt work?
During the Glenn procedure, the surgeon disconnects the superior vena cava (SVC) from the heart and connects it to the pulmonary artery. Now the blood from the upper part of the body flows directly into the pulmonary artery. The pulmonary artery takes the blood to the lungs.
When is the Glenn procedure done?
The Glenn procedure is the second of three congenital open heart surgeries performed to correct hypoplastic left heart syndrome (HLHS) and other single ventricle heart defects. It is usually performed about six months after birth, following the Norwood procedure.
Why is a Glenn bidirectional?
The bidirectional Glenn procedure directs the blood flow from the upper body veins directly to the lungs rather than the heart pumping the blood to the lungs first.
What is Sano procedure?
The Sano shunt is a palliative surgical technique sometimes used as a step in Norwood procedure for hypoplastic left heart syndrome. The procedure involves placement of an extracardiac conduit between the right ventricle and main pulmonary artery stump.
What does the Fontan procedure do?
The Fontan procedure refers to any surgical procedure that leads to systemic flow of venous blood to the lungs without passing through a ventricle.
What is Glenn pressure?
Bidirectional Glenn Operation This generally results in arterial saturations between 75% and 85%, an SVC pressure of 10 to 12 mmHg, and an atrial pressure of 5 to 6 mmHg. SVC pressure exceeding 16 mmHg or a transpulmonary gradient exceeding 8 to 10 mmHg should prompt critical appraisal of the anastomosis.
What is normal Glenn pressure?
How old is the oldest Fontan patient?
Mean follow-up after the Fontan operation was 15.3 ± 9.3 years (median: 15.1 years; range: 34 days to 37 years). The oldest survivor after the Fontan operation was 67 years of age (Fontan at age 39 years)….Results.

How is a shunt removed in the Glenn procedure?
In the Glenn procedure: The superior vena cava (SVC) (which brings blood back from the upper part of the body) is disconnected from the heart and connected directly to the pulmonary artery. The shunt placed during the Norwood procedure is removed.
Where does the Glenn procedure take place in the heart?
The Glenn procedure, the way it is currently performed involves hooking up the superior vena cava to the right pulmonary artery and detaching it from the right atrium.
What are the goals of the Glenn procedure?
The Glenn procedure is a type of open-heart surgery. The goals are to: Make blood from the upper part of the body (the head, neck, and arms) go directly to the lungs . This lets the blood pick up oxygen without passing through the heart. Take some of the extra work away from the right ventricle .
When does a baby get the Glenn procedure?
After the Norwood procedure, babies get the Glenn procedure when they’re between 4 and 6 months old. This is because they outgrow the shunt placed during the Norwood procedure. What Is the Glenn Procedure? The Glenn procedure is a type of open-heart surgery.
