Mitral valve prolapse syndrome

Mitral valve prolapse syndrome (MVP Syndrome), also referred to as mitral valve prolapse dysautonomia, is thought to represent an imbalance of the autonomic nervous system in association with mitral valve prolapse. The underlying etiology that causes both autonomic dysregulation and the structural abnormalities present in mitral valve prolapse is unknown. Most patients who suffer from mitral valve prolapse syndrome may have an underlying dysautonomia as the cause of their symptoms. In particular, supraventricular arrhythmias such as those observed with MVP syndrome are associated with increased parasympathetic tone.[1]

Symptoms generally attributed to MVP syndrome include palpitations, shortness of breath, and syncope. Because of the low specificity of these symptoms, and the fact that there is significant overlap in the causes of these symptoms with sequelae of significant mitral regurgitation often seen with mitral valve prolapse, MVP syndrome is most likely over-diagnosed.[2] The uncertainty regarding the frequency of this syndrome may in part be due to the fact that there is no consensus criteria to diagnose MVP syndrome.
