What is an Extracardiac Fontan?
The extracardiac Fontan uses an external conduit to anastomose the inferior vena cava into the pulmonary arteries, whereas a lateral tunnel Fontan uses a baffle within the right atrium (Figure 1).
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.
Why is Fontan fenestrated?
Fenestration of the Fontan circuit allows for shunting of deoxygenated blood to the systemic circulation. This procedure improved the clinical outcomes of patients who are at high risk for poor Fontan results. However, it is controversial whether fenestration is beneficial for standard-risk patients.

What is a classic Fontan?
The classic Fontan procedure was first performed in 1968 and consisted in the creation of anastomoses between the superior vena cava and the right pulmonary artery and between the inferior vena cava and the left pulmonary artery by means of valvular homografts [1].
Can your heart be on the right?
If you have isolated dextrocardia, your heart is located on the right side of your chest, but it has no other defects. Dextrocardia can also occur in a condition called situs inversus. With it, many or all of your visceral organs are on the mirror-image side of your body.
