Front 1

What is Tetralogy of Fallot?

Back 1

Pulmonary Stenosis, Overriding Aorta, VSD, right venticular hypertrophy

Front 2

What happens to blood in the right atrium in Tetralogy of Fallot?

Back 2

goes to right ventricle, because of pulmonary stenosis gets shunted through VSD into left heart without oxygenation.

Front 3

How does Tetralogy of Fallot present?

Back 3

with the murmur of pulmonary stenosis and cyanosis

Front 4

Why is severe cyanosis from TOF rare immediately after birth?

Back 4

The PDA allows additional pulmonary blood flow

Front 5

What is a Tetralogy spell?

Back 5

sudden drop in arterial oxygen saturation resulting from a sudden increased constriction of the outflow tract to the lungs so that pulmonary blood flow is further restricted.

Front 6

What happens to a child with TOF when given supplemental oxygen?

Back 6

Has little effect

Front 7

What is "pink" tetralogy of Fallot?

Back 7

normal oxygen levels because pulmonary stenosis is mild

Front 8

How do you treat a child with TOF whose oxygen level is critically low after birth?

Back 8

prostaglandin infusion is to keep the ductus arteriosus open and provide additional pulmonary blood flow

Front 9

When is TOF repaired?

Back 9

Complete repair is usually done electively when the children are about six months of age, as long as the oxygen levels remain adequate

Front 10

how is TOF repaired?

Back 10

Closure of VSD with synthetic Dacron patch, pulmonary valve and right ventricular outflow tract is then augmented by resecting obstructive muscle tissue in the RV

Front 11

How is long term function after TOF repair?

Back 11

excellent

Front 12

What abnormality is left after TOF repair?

Back 12

leaky (insufficient) pulmonary valve; may lead to RV dilatation

Front 13

How do you treat a tetralogy spell?

Back 13

sometimes by comforting the infant and flexing the knees forward and upward. Most often, however, immediate medical attention is necessary.
