Q. A 3-day-old male was born one week premature. You are called to the newborn nursery to evaluate the patient because staff detected a heart murmur. The infant's birth history includes a vacuum extraction delivery, and APGAR scores of 7 at 1 minute and 9 at 5 minutes. On physical examination, he is alert and active, with good color and tone. His head is symmetrical and without any obvious cranial deformities, the fontanelles are soft and flat, and the suture lines are symmetrical. His eyes are clear, with no discharge or redness. The patient’s blood pressure is 65/40 mm Hg, heart rate 175/min, respiratory rate 40/min, and oxygen saturation is 99 percent on room air. His length, weight, and head circumference are in the 75th percentile. His chest is symmetrical and good expansion with each breath is noted. The lungs demonstrate clear breath sounds with no rales, wheezing, or crackles. Cardiac assessment reveals a continuous holosystolic machinery-like murmur below the clavicle, radiating to the back. The infant also has a prominent precordial impulse and bounding peripheral pulses. His remaining physical examination is within normal limits and no additional concerns are noted. Assuming the most likely diagnosis, which of the following statements is NOT true?
