Cooing dove murmur
- “seagull’s cry murmur” is defined as a murmur imitating the cooing sound of a seagull. This type of murmur is typically characterised by a musical timbre and a high frequency
- occur as a result of various valve diseases.
- It is usually described as a sign of tight calcific aortic stenosis, when the murmur’s high frequency components are transmitted to the lower left sternal border and the cardiac apex during most of systole (Gallavardin’s phenomenon).
- Other causes –
- Severe aortic valve regurgitation -protodiastolic murmur with similar characteristics, typically in decrescendo, may occur in severe aortic valve regurgitation, particularly when the regurgitant flow presents high velocities
- Mitral regurgitation -seagull’s cry murmur may also be the sign of mitral regurgitation or prolapse. Similarly, the musical and holosystolic sound reflects the presence of high frequency components due to high velocities of reflow.
