The bidirectional Glenn procedure connects which two structures?
Answer: Superior vena cava end-to-side to the right pulmonary artery
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.
At what approximate age is Fontan completion typically performed following the bidirectional Glenn procedure?
Answer: 2 to 4 years of age
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.
Coarctation of the aorta most commonly occurs at which anatomical location?
Answer: Juxtaductal position near the insertion of the ligamentum arteriosum
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).
Total anomalous pulmonary venous connection (TAPVC) requires urgent surgical repair when which condition is present?
Answer: Pulmonary venous obstruction causing severe cyanosis and pulmonary edema
Obstructed TAPVC is a surgical emergency because pulmonary venous obstruction causes severe pulmonary edema, profound hypoxemia, and cardiovascular collapse without urgent repair.
In Ebstein anomaly, what is the primary anatomical abnormality of the tricuspid valve?
Answer: Apical displacement of the septal and posterior leaflets into the right ventricle
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.
Which surgical technique for Ebstein anomaly repair involves detaching and rotating the available leaflet tissue to create a cone-shaped valve?
Answer: Cone reconstruction (da Silva technique)
The cone reconstruction (da Silva technique) detaches, rotates, and reattaches the leaflet tissue to create a three-dimensional cone resembling a normal tricuspid valve, with superior long-term outcomes.
In the Collett and Edwards classification, what defines Type I truncus arteriosus?
Answer: A short main pulmonary artery segment arising from the left side of the common truncal root
Type I truncus (most common) features a short main pulmonary artery segment arising from the common truncal root before dividing into left and right pulmonary arteries.
