Key result
Dove-coo murmur in AR coincides with aortic posterior wall fluttering during mitral opening, suggesting resonance.
Why the study?
The mechanism of generation of the triphasic dove-coo murmur in aortic regurgitation was not well understood.
Population
A patient with aortic regurgitation and triphasic dove-coo murmur
Design
Case report using simultaneous phonocardiography and dual echocardiography

May explain rarity of dove-coo murmur in rheumatic AR; hypothesis-generating from single case report.
Case Report (n=1)
No
The dove-coo murmur in aortic regurgitation requires normal mitral valve opening and closure, explaining its rarity in rheumatic aortic regurgitation where mitral opening is often restricted.
Kohno et al. (1981) conducted a case report in Aortic regurgitation with dove-coo murmur (n=1). Simultaneous phonocardiography and dual echocardiography was evaluated on Mechanism of dove-coo murmur generation. The dove-coo murmur in aortic regurgitation arose coincident with the coarse regular fluttering of the aortic posterior wall during mitral valve opening, suggesting it is produced by resonance.
