Two- and three-dimensional echocardiography are valuable in the diagnosis of MVP as they allow visualization of the mitral leaflets relative to the mitral annulus. This allows measurement of the leaflet thickness and their displacement relative to the annulus. Thickening of the mitral leaflets >5 mm and leaflet displacement >2 mm indicates classic mitral valve prolapse.


2D Echo features

To diagnose mitral valve prolapse on 2D echocardiography, the following criteria should be fulfilled:[1]

  1. Movement of either leaflet more than 2 mm superiorly into the left atrium during systole in the parasternal long axis view with leaflet thickness of at least 5 mm
  2. Movement of the point of co-aptation behind the annular plane in the apical 4 chamber view.

Other findings on echo include enlarged LA size thick and redundant leaflets and chordae, chordal elongation, and annular dilatation. Reduced tensile strength leads to progressive elongation or rupture of chordae that usually appear as flail segments.[2]


Doppler echocardiography is important in detecting the severity of the mitral valve prolapse. Color flow mapping and CW doppler show predominantly late systolic mitral regurgitation. Severe mitral regurgitation is usually condsidered in the presence of one ore more of the following findings: [2]

  1. Vena contracta width >0.7 cm
  2. Large central mitral regurgitation jet (area >40% of left atrium)
  3. Pulmonary vein reversal
  4. Effective regurgitant orifice >40 mm2
  5. Regurgitant fraction >50%
  6. Regurgitant volume >60 cc

The proximal isovelocity surface area (PISA) method is also used to determine severity of mitral valve prolapse. PISA can usually be detected in almost all severe cases of mitral regurgitation but in only half of cases of mild regurgitation. [3]

Asymptomatic Patients (DO NOT EDIT) [4]

Class I
"1. Echocardiography is indicated for the diagnosis of MVP and assessment of MR, leaflet morphology, and ventricular compensation in asymptomatic patients with physical signs of MVP. (Level of Evidence: B)"
Class III
"1. Echocardiography is not indicated to exclude MVP in asymptomatic patients with ill-defined symptoms in the absence of a constellation of clinical symptoms or physical findings suggestive of MVP or a positive family history. (Level of Evidence: B)"
"2. Routine repetition of echocardiography is not indicated for the asymptomatic patient who has MVP and no MR or MVP and mild MR with no changes in clinical signs or symptoms. (Level of Evidence: C)"
Class IIa
"1. Echocardiography can effectively exclude MVP in asymptomatic patients who have been diagnosed without clinical evidence to support the diagnosis. (Level of Evidence: C)"
"2. Echocardiography can be effective for risk stratification in asymptomatic patients with physical signs of MVP or known MVP. (Level of Evidence: C)"
