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.
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.
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.
Certain heart sounds can also be diagnosed using sonography. Ultrasound is a great way to visualize valvular abnormalities. We recommend the website ultrasound.guide for free training.
