Systolic Murmur - Aortic Stenosis

Essential Heart Sounds

In this lesson we cover a diamond shaped systolic murmur associated with aortic stenosis. When you listen to the recording, notice that the first and second heart sounds are normal. The systolic murmur starts shortly after the first heart sound and ends before the second heart sound. This murmur is mid to high-pitched. Use the 'Visual' tab to play a video that presents a markedly thickened left ventricle. The murmur is caused by turbulent flow across the stenotic aortic valve. The aortic valve leaflets are thickened and immobile.
