Difficulty: MediumCardiovascular System

Match each valvular heart disease with its most characteristic constellation of physical examination findings.

  • Severe Aortic StenosisPulsus parvus et tardus, paradoxical splitting of S2, and a harsh crescendo-decrescendo systolic murmur
  • Chronic Severe Aortic RegurgitationWidened pulse pressure, bounding pulses with rapid rise and fall, and an early diastolic decrescendo murmur
  • Severe Mitral StenosisLoud S1, an opening snap, and a low-pitched mid-diastolic rumbling murmur best heard at the apex
  • Chronic Severe Mitral RegurgitationLaterally displaced apical impulse, S3 gallop, and a blowing holosystolic murmur radiating to the axilla

Answer

Severe Aortic Stenosis matches with pulsus parvus et tardus and a crescendo-decrescendo systolic murmur. Chronic Severe Aortic Regurgitation matches with a widened pulse pressure and an early diastolic decrescendo murmur. Severe Mitral Stenosis matches with a loud S1, an opening snap, and a mid-diastolic rumbling murmur. Chronic Severe Mitral Regurgitation matches with a laterally displaced apical impulse, an S3 gallop, and a holosystolic murmur.
Each valvular pathology has distinct hemodynamic consequences that manifest as specific physical examination findings, allowing for accurate clinical matching based on pulse characteristics, extra heart sounds, and murmur timing.

Step-by-Step Solution

1
Identify the timing of the murmur (systolic vs. diastolic) for each clinical presentation.
Two presentations describe systolic murmurs, while the other two describe diastolic murmurs.
Murmur timing narrows the diagnosis to either stenosis or regurgitation of a specific valve during that phase of the cardiac cycle.
2
Evaluate the associated peripheral vascular findings.
Pulsus parvus et tardus is specific to outflow obstruction (aortic stenosis). Widened pulse pressure and bounding pulses are specific to aortic runoff (aortic regurgitation).
Peripheral pulse characteristics are often pathognomonic for left-sided valvular lesions and help confirm the specific pathology.
3
Analyze additional cardiac auscultation and palpation findings.
An opening snap points to mitral stenosis, while an S3 gallop with a displaced point of maximal impulse indicates volume overload typical of chronic mitral regurgitation.
Extra heart sounds and the location of the apical impulse differentiate between various mitral pathologies.
