  • Aortic Regurgitation
  • Austin Flint Murmur

    S1 is soft; S2 is obscured by a soft regurgitant murmur and a louder, low-pitched, late-diastolic murmur. The diastolic murmur mimics mitral stenosis and is attributed to mitral valve leaflet vibration or mild obstruction caused by rapid regurgitant flow.
