Cooing dove murmur

The "cooing dove" murmur is a cardiac murmur with a musical quality (high pitched - hence the name) and is associated with acute mitral valve regirgitation, preceded by rupture of the chordae tendinea (the fibrous "strings" that connects the papillary muscle to the cusps of the valves). It is a diastolic murmur which is best heard over the left 2nd, 3rd and forth intercostal spaces.
