Match the following classic auscultatory and physical exam findings with their most likely underlying structural heart disease.
- Harsh systolic crescendo-decrescendo murmur at the left lower sternal border that increases in intensity with the Valsalva maneuverHypertrophic cardiomyopathy
- Low-pitched, mid-diastolic rumble heard best at the apex in the left lateral decubitus position, preceded by an opening snapMitral stenosis
- High-pitched, blowing, early diastolic decrescendo murmur heard best at the left sternal border with the patient leaning forwardAortic regurgitation
- Late-peaking systolic crescendo-decrescendo murmur at the right upper sternal border with delayed and diminished carotid pulsesAortic stenosis
- Holosystolic, high-pitched blowing murmur heard best at the apex with radiation to the left axillaMitral regurgitation
Answer
The accurate pairings match each specific auscultatory finding to its corresponding structural pathology: Valsalva-responsive murmur with hypertrophic cardiomyopathy, opening snap with mitral stenosis, early diastolic decrescendo murmur with aortic regurgitation, delayed carotid pulses with aortic stenosis, and holosystolic murmur radiating to the axilla with mitral regurgitation.
Each physical exam finding uniquely identifies a structural heart lesion. Hypertrophic cardiomyopathy is characterized by dynamic obstruction worsening with decreased preload (Valsalva). Mitral stenosis produces an opening snap and diastolic rumble. Aortic regurgitation presents with a blowing diastolic murmur. Aortic stenosis is identified by a late-peaking systolic murmur and delayed, diminished pulses. Mitral regurgitation causes a holosystolic murmur that radiates to the axilla.
