Mild Aortic Stenosis - Auscultation Lesson

Aortic stenosis has a murmur characterized by an aortic ejection click in early systole, followed by a diamond-shaped systolic murmur that ends mid-way through systole. The murmur has a mid-frequency pitch. As the condition worsens, the murmur frequency increases.

The first heart sound is normal. The second heart sound is physiologically split. The aortic component of the second heart sound is louder than normal.

The anatomy video shows thickened aortic valve leaflets with decreased movement. The left ventricle wall thickness is increased.
