Aortic Stenosis Page

Introduction

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.

Video

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.

Listening Tips

Systole: Diamond shaped, harsh, high pitch, late peaking murmur.

Ultrasound

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 ultrasound training courses.
