Difficulty: EasyCardiovascular System

Match the following classic physical examination findings (heart murmurs and sounds) with their most likely underlying valvular pathology.

  • Aortic stenosisCrescendo-decrescendo systolic murmur at the right upper sternal border with radiation to the carotids
  • Mitral regurgitationHolosystolic murmur at the apex with radiation to the axilla
  • Mitral stenosisOpening snap followed by a low-pitched mid-diastolic rumble at the apex
  • Aortic regurgitationHigh-pitched, early diastolic decrescendo murmur at the left sternal border

Answer

Aortic stenosis matches with the crescendo-decrescendo systolic murmur radiating to the carotids; Mitral regurgitation matches with the holosystolic murmur radiating to the axilla; Mitral stenosis matches with the opening snap and mid-diastolic rumble; Aortic regurgitation matches with the early diastolic decrescendo murmur.
Each valvular lesion produces characteristic hemodynamic changes resulting in classic auscultatory findings. Recognizing these murmurs by timing, location, and radiation is essential for initial clinical diagnosis.

Step-by-Step Solution

1
Analyze the timing of the murmurs (systolic vs. diastolic).
The crescendo-decrescendo and holosystolic murmurs are systolic, correlating with Aortic stenosis and Mitral regurgitation. The mid-diastolic rumble and early diastolic decrescendo murmurs are diastolic, correlating with Mitral stenosis and Aortic regurgitation.
Timing within the cardiac cycle is the essential first step in differentiating valvular lesions.
2
Identify the location of maximal intensity and specific characteristics for the systolic murmurs.
The right upper sternal border with carotid radiation confirms Aortic stenosis. The apex with axillary radiation confirms Mitral regurgitation.
Specific auscultation locations and radiation patterns definitively differentiate the systolic murmurs.
3
Identify the location of maximal intensity and specific characteristics for the diastolic murmurs.
The apex with an opening snap confirms Mitral stenosis. The left sternal border confirms Aortic regurgitation.
Extra heart sounds (like an opening snap) and specific locations definitively identify the diastolic murmurs.
