The aortic valve leaflets are thickened and immobile. The murmur is caused by turbulent flow across the stenotic aortic valve. play pause Maneuver:Sitting Chestpiece Position:Aortic Chestpiece:Diaphragm Table of Contents Introduction First and Second Heart Sounds - Normal and Unsplit First and Second Heart Sounds - Reduced Intensity Second Heart Sound - Splitting Third Heart Sound Gallop Fourth Heart Sound Gallop Third and Fourth Heart Sound Gallop Summation Gallop at 120 beats per minute Second Heart Sound - Fixed Splitting Mid-Systolic Click Mitral Valve Leaflet Prolapse Aortic Stenosis (Diamond Shaped Systolic Murmur) Aortic Regurgitation (Decrescendo Diastolic Murmur) Mitral Regurgitation (pansystolic Murmur) Mitral Stenosis (Diastolic Murmur)
