Presentation reference

Is it this?

Reference only, to read alongside your own examination.

Symptoms — what the patient reports (2)

  • Most patients with MVP are asymptomatic; when symptoms occur they tend to be autonomic in nature
  • Higher-risk history includes sustained palpitations or complex ventricular arrhythmia, Marfan or connective tissue disease, exertional or emotional presyncope/syncope, or a first-degree relative with MVP-related sudden death [arrhythmia · palpitations · sudden cardiac arrest · syncope]

Signs — what you find (3)

  • Squatting delays the click and shortens the murmur, while standing or Valsalva brings the click earlier and lengthens the murmur [heart murmur]
  • Handgrip delays the MVP click and shortens its murmur, but quiets the murmur of hypertrophic cardiomyopathy - a useful way to tell the two apart [heart murmur]
  • With a flail leaflet the click may disappear, replaced by a holosystolic murmur resembling mitral regurgitation [heart murmur]

Tests (6)

  • Transthoracic echo is the primary diagnostic test; MVP is defined by leaflet displacement of 2 mm or more above the annular plane
  • Classic MVP pairs that displacement with leaflet thickness over 5 mm; nonclassic MVP has thickness of 0 to 5 mm
  • On cardiac MRI, the extent of midwall late gadolinium enhancement is the strongest predictor of arrhythmic MVP
  • A mechanical dispersion index of 65 ms or more on CMR is another, less-robust predictor of arrhythmic MVP
  • ECG changes can include inferior T-wave inversion, Tpeak-Tend beyond 90 ms, or PVCs from the papillary muscles/outflow tract with right-bundle morphology
  • Holter monitoring is considered when a high PVC burden, 5% or more, is suspected

If not this — what else fits (2)

  • Hypertrophic cardiomyopathy, which the handgrip maneuver helps tell apart from MVP
  • Other causes of mitral regurgitation: secondary MR from papillary dysfunction, rheumatic disease, infective endocarditis with leaflet damage, annular calcification, and congenital cleft mitral valve

NO DRUG THERAPY IN PRIMARY CARE (RECOGNITION & REFERRAL)

1st line
Adult dose and duration

Mitral valve prolapse is most commonly an asymptomatic, benign echocardiographic finding. In primary care, reassure asymptomatic patients without significant regurgitation that routine antibiotic prophylaxis is not required. Refer to cardiology if the patient develops symptoms such as palpitations, chest pain, syncope, severe mitral regurgitation, or signs of heart failure. - Refer

Paediatric dose

Children follow the same pathway: recognise and refer. No primary-care medicine is implied.

No dose - referral pathway, no medicine given in primary care

Why

Mitral valve prolapse is most commonly an asymptomatic, benign echocardiographic finding. In primary care, reassure asymptomatic patients without significant regurgitation that routine antibiotic prophylaxis is not required. Refer to cardiology if the patient develops symptoms such as palpitations, chest pain, syncope, severe mitral regurgitation, or signs of heart failure.

Cautions
  • RED FLAG - Infective endocarditis presentation (fever, new or changing murmur): assess urgently and refer.
  • RED FLAG - Embolic stroke / TIA: assess urgently and refer.
  • Significant valve regurgitation, palpitations or arrhythmia, chest pain, symptoms of heart failure.
  • No medicine is prescribed for this in primary care - this entry is for recognition and referral. Anything given is decided by the service it is referred to.
  • RED FLAG - Family history of arrhythmogenic mitral valve prolapse (AMVP) requires cardiology evaluation/referral for primary prevention strategies such as ICDs.
