Q: What is Gallavardin phenomenon?
Answer: 95 years ago Dr. Gallavardin reported that murmur of aortic valve stenosis may change its quality and becomes musical at the apex. This can be confused as a murmur of mitral regurgitation. Both murmurs can be differentiated by the fact that the apical murmur of the Gallavardin phenomenon does not radiate to left axilla.
