Mitral valve prolapse, also known as click-murmur syndrome, Barlow's syndrome, balloon mitral valve, or floppy valve syndrome, is the bulging of one or both of the mitral valve flaps during the contraction of the heart.
One or both of the flaps may not close properly, allowing the blood to leak backward. This may result in a mitral regurgitation murmur.
Mitral Valve Prolapse When the heart’s left atrium and left ventricle don’t close properly, this is called mitral valve prolapse (MVP), reversing blood flow or regurgitation. Mitral Valve ProlapseMVPclick-murmur syndrome
