Cardiovascular 15

A 17-year-old boy presents to his primary care physician to discuss shortness of breath while playing basketball, which has worsened over the past few years. Past medical history is noncontributory, and he takes no medications. Family medical history is significant for the sudden death of the patient’s father (who was otherwise healthy) at age 36. Physical examination reveals a cardiac murmur. Electrocardiogram reflects normal sinus rhythm with a left axis deviation. An echocardiogram confirms the presence of left ventricular hypertrophy.

Which of the following findings is most likely present on physical exam?

  • A) Crescendo-decrescendo systolic murmur at the right upper sternal border
  • B) Crescendo-decrescendo systolic murmur at the lower left sternal border
  • C) Decrescendo diastolic murmur at the left upper sternal border
  • D) Midsystolic murmur with wide and fixed S2 splitting
  • E) Soft and delayed aortic component of S2
