Changes

Fractional shortening may be increased (hyperynamic left ventricle). This is because, in the setting of mitral regurgitation, impedance to ventricular emptying is reduced (blood can be ejected into the low pressure left atrium)and end-diastolic ventricular stretch is increased by the addition of the regurgitant fraction, increasing the force of contraction.

A serious complication of DMVD is chordae tendinae rupture, resulting in a 'flail leaflet' and acute worsening of mitral regurgitation. A leaflet segment typically 'flails' back into the left atrium during systole.

'''Left atrial rupture''' is a major complication of DMVD. Left atrial endocardial and endomyocardial splits are usually multiple and may heal or perforate the atrial wall, causing hemopericardium or an acquired atrial septal defect depending on their depth and location.
