MVP murmur is associated with which auscultatory finding?

• A. Mid-Systolic Click
• B. Holosystolic Murmur at Apex Radiating to Axilla
• C. Early Diastolic Murmur at Apex
• D. Continuous Murmur

Answer: (A)

Mitral valve prolapse is best identified by a midsystolic click. This click occurs as the mitral valve leaflets suddenly billow (prolapse) into the left atrium during systole, causing a brief abrupt tension of the chordae tendineae and a characteristic sound timing. If mitral regurgitation accompanies MVP, there can also be a late systolic murmur following the click, but the defining auscultatory feature is the midsystolic click. The other patterns described fit different conditions: a holosystolic murmur at the apex radiating to the axilla points to mitral regurgitation without MVP’s click; an early diastolic murmur at the apex isn’t MVP; a continuous murmur suggests a PDA or similar lesion.
