Aortic stenosis (AS) refers to a tightening of the aortic valve at the origin of the aorta. Aortic stenosis is associated with an ejection systolic murmur heard loudest over the aortic valve. The murmur is described as having a ‘crescendo-decrescendo’ quality (it appears as diamond-shaped on a phonogram). WebThe degree of severity is assessed using several components of the ultrasound exam, especially Doppler ultrasound, which measures the direction and flow of blood as it courses through the heart.
