Aortic Stenosis (Diamond Shaped Systolic Murmur) C31 | #123

This is an auscultation example of a diamond shaped systolic murmur associated with aortic stenosis. The first and second heart sounds are normal. The murmur starts shortly after the first heart sound and ends before the second heart sound. The murmur is mid to high-pitched. The anatomy video shows a markedly thickened left ventricle. The aortic valve leaflets are thickened and immobile. The murmur is caused by turbulent flow across the stenotic aortic valve.
