Aortic Stenosis Page
Welcome to the aortic stenosis page. On this page we provide a definition, sample heart sounds and links to the training lessons available on this site.
What is Aortic Stenosis?
Aortic valve stenosis is a narrowed value opening. It restricts blood outflow from the heart to the aorta.
This video is an animation of Systolic Murmur - Aortic Stenosis. While playing the animation, observe the heart valves and blood flow, which are the source of heart murmurs.
Aortic Stenosis Auscultation
This is often a loud murmur heard early in systole. It has a diamond shaped appearance when viewed on the phonocardiograph, which is heard when the murmur rises in sound intensity.
The murmur is characterized by regular vibrations which give the murmur a musical quality ("cooing").
This is caused by turbulent blood flow into the aorta.
S1 and S2 are normal. Diastole is silent.
