What is a bilateral bidirectional Glenn?

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. The bidirectional Glenn shunt redirects blood flow from the upper body veins and is often performed prior to having a Fontan procedure.

Why is Glenn called bidirectional?

Since the blood passing from the SVC into the pulmonary arterial system flows bidirectionally to both right and left lungs, it is called a bi-directional Glenn procedure.

What is bidirectional cavopulmonary anastomosis?

The Glenn procedure is formally known as the bi-directional cavopulmonary anastomosis. This procedure is done when only one ventricle works properly and not enough blood is getting to the lungs. The superior vena cava returns blood from the upper half of the body to the right atrium.

When do you do the Glenn procedure?

It’s usually done when a child is 18 to 36 months (3 years) of age.

What is normal 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 causes Glenn head?

After the Glenn procedure, “Glenn Head” is common. It is like having a severe headache or migraine, which is caused by your child’s new circulatory system.

How long do Fontan patients live?

Since Francis Fontan first described his pioneering operation in 1968, cardiac defects that were once uniformly fatal in infancy and childhood have now be palliated well into adulthood, with an overall estimated 30-year survival of over 80%.

What is a normal Glenn pressure?

What is a Fontan heart procedure?

The Fontan procedure refers to any surgical procedure that leads to systemic flow of venous blood to the lungs without passing through a ventricle. In 1971, Fontan and Baudet (1) described a surgical procedure for repair of tricuspid atresia that built on experimental and clinical research from the 1940s.

What is lateral tunnel Fontan?

The extracardiac lateral tunnel (ELT) is a modification of the Fontan procedure which uses pericardium and the external surface of the atrium to create a conduit from the inferior vena cava to the pulmonary artery.

What are the 3 surgeries for HLHS?

Surgery for hypoplastic left heart syndrome usually is done in three separate stages:

• Norwood Procedure. This surgery usually is done within the first 2 weeks of a baby’s life.
• Bi-directional Glenn Shunt Procedure. This usually is performed when an infant is 4 to 6 months of age.
• Fontan Procedure.

What is a super Glenn?

The Super Glenn procedure involves targeted increased in blood flow to left sided heart structures with fenestrated atrial septation.
