Question 1

The bidirectional Glenn procedure connects which two structures?

Accepted Answer

Superior vena cava end-to-side to the right pulmonary artery

Answer

The bidirectional Glenn shunt connects the superior vena cava end-to-side to the right pulmonary artery, directing upper body venous return passively to both lungs without ventricular pumping.

Question 2

At what approximate age is Fontan completion typically performed following the bidirectional Glenn procedure?

Accepted Answer

2 to 4 years of age

Answer

Fontan completion is typically performed between ages 2 and 4 years, after adequate reduction of pulmonary vascular resistance has been achieved following the Glenn procedure.

Question 3

Coarctation of the aorta most commonly occurs at which anatomical location?

Accepted Answer

Juxtaductal position near the insertion of the ligamentum arteriosum

Answer

Coarctation most commonly occurs at the juxtaductal position in the proximal descending thoracic aorta, near the insertion of the ligamentum arteriosum (remnant of the ductus arteriosus).

Question 4

Total anomalous pulmonary venous connection (TAPVC) requires urgent surgical repair when which condition is present?

Accepted Answer

Pulmonary venous obstruction causing severe cyanosis and pulmonary edema

Answer

Obstructed TAPVC is a surgical emergency because pulmonary venous obstruction causes severe pulmonary edema, profound hypoxemia, and cardiovascular collapse without urgent repair.

Question 5

In Ebstein anomaly, what is the primary anatomical abnormality of the tricuspid valve?

Accepted Answer

Apical displacement of the septal and posterior leaflets into the right ventricle

Answer

Ebstein anomaly is characterized by downward (apical) displacement of the tricuspid valve's septal and posterior leaflets into the right ventricle, creating an atrialized portion of the RV.
