Hint : Extra flow = extra noise 🔊

Correct Answers:

  • Systolic murmur


Rationale :

🔊 A PDA causes abnormal blood flow between the aorta and the pulmonary artery

🔊 This extra flow creates a characteristic systolic murmur, often described as "machinery-like"

🔊 The murmur is best heard at the left upper sternal border

🔊 Other signs can include bounding pulses and signs of heart failure, but chronic hypoxemia, cyanosis, or weak pulses are more common in cyanotic defects, not PDA
