Mitral Valve Leaflet Prolapse

Virtual Auscultation

The patient's position is supine.

Lesson

In this case, a mid-systolic click is immediately followed by a late systolic diamond-shaped murmur that runs to the end of systole. The intensity of the murmur increases and its starting point begins earlier in systole as left ventricular volume decreases (going from supine to standing).

On the anatomy video you can see that the murmur is caused by the prolapse of the posterior mitral valve leaflet. The murmur is represented by turbulent flow from the left ventricle into the left atrium.

Play the animation and take note of the prolapse of both the anterior and posterior mitral valve leaflets and turbulent flow across the incompetent mitral leaflets (murmur of mitral regurgitation).
