Gallavardin phenomenon
System: Heart & Circulation Signs · All heart & circulation signs
What it is — and how it is elicited
The murmur of aortic stenosis seems to split: harsh noise radiates to the neck while a musical, mitral-like murmur is heard at the apex.
What a positive finding suggests
Associated with aortic stenosis, especially calcific disease in older adults; the apex component can be mistaken for mitral regurgitation.
◈ Behind the name
Louis Gallavardin (1875–1957), French cardiologist.

Please note: This page is an educational reference about clinical examination signs. A clinical sign supports — and never replaces — a full clinical evaluation, examination and appropriate testing. A sign being present does not by itself prove a diagnosis, and an absent sign does not rule one out. If you have symptoms that worry you, see a health professional.
