Aortic Stenosis

This murmur is systolic, crescendo-decrescendo in shape, harsh in quality, located in the sash distribution (clavicle to apex), and radiates to clavicle or neck. Causes are usually calcification in older patients (age > 50) and congenital bicuspid valve in younger patients (age < 50).

Patient 1

This is an older man who was admitted to the hospital with a pathologic C6 fracture and was found to have severe aortic stenosis. Echocardiogram showed an aortic valve area of 0.8 cm2. The murmur peaks late in systole. Also note that over the apex, the murmur takes on a musical quality (Gallavardin phenomenon).
