Systolic Murmurs - Late Aortic Stenosis

This is a typical example of the late-peaking murmur of aortic stenosis. Notice that the murmur is in later systole, with a harsh quality and a crescendo-decrescendo shape. Because this is late-peaking, it would suggest a more severe stage of aortic stenosis than an early peaking murmur. Additionally, there is a nearly-absent S2, again indicating that the valve is poorly mobile and severely diseased.
