Cardiology Murmurs

Austin Flint Murmur

Aortic Regurgitation any be associated with a low-pitched, “blubbering”, mid-to-late diastolic murmur heard over the apex, known as the Austin Flint murmur. The mechanism is thought to be distortion and early closure of the anterior leaflet of the mitral valve caused by the regurgitant aortic jet, resulting in functional mitral stenosis.
