Question 1
A 3-month-old infant with a known perimembranous ventricular septal defect (VSD) is evaluated on follow-up echocardiography. The defect size has decreased from 6 mm to 2 mm. Which anatomical structure is primarily responsible for the spontaneous closure or reduction in size of perimembranous VSDs?
Correct Answer:
Tricuspid valve septal leaflet tissue and pouch formation
Question 2
An asymptomatic 4-year-old child is referred for evaluation of a cardiac murmur discovered during a routine check-up. Auscultation reveals a wide, fixed splitting of the second heart sound (S2) and a 2/6 mid-systolic ejection murmur at the upper left sternal border. What is the underlying cause of the wide, fixed split S2?
Correct Answer:
Persistent volume overload of the right ventricle causing delayed closure of the pulmonary valve regardless of respiration
Question 3
A 28-week premature infant weighing 950 grams develops bounding peripheral pulses, a hyperdynamic precordium, and a continuous machinery murmur at the left infraclavicular area on day 4 of life. Chest radiography shows cardiomegaly and pulmonary plethora. Before initiating intravenous ibuprofen for ductal closure, which clinical condition represents an absolute contraindication?
Correct Answer:
Active necrotizing enterocolitis (NEC) or intestinal perforation
Question 4
A newborn with trisomy 21 (Down syndrome) undergoes a screening electrocardiogram (ECG) on day 2 of life. The ECG demonstrates a superior QRS axis (-60 to -120 degrees) with counterclockwise frontal loop rotation and first-degree AV block. Which congenital cardiac lesion is most strongly associated with these ECG findings?
Correct Answer:
Complete Atrioventricular Septal Defect (AVSD)
Question 5
A 10-day-old infant is brought to the emergency department in severe circulatory shock with tachypnea, poor perfusion, and profound metabolic acidosis. Femoral pulses are absent, whereas brachial pulses are palpable. Echocardiography confirms severe coarctation of the aorta with closure of the ductus arteriosus. What is the immediate first-line medical intervention?
Correct Answer:
Continuous intravenous infusion of Prostaglandin E1 (Alprostadil)
