  32. Mitral regurgitation – pathophysiology • Leaking mitral valve •  LV emptying •  LV filling •  LV dilatation • LV stretch  contractile failure •  LA pressure • LA stretch • Atrial arrhythmia (atrial fibrillation) • Thrombo-embolic risk • stroke (cerebrovascular accident) • heart attack (myocardial infarct)

  33. Mitral regurgitation – pathophysiology • Leaking mitral valve valve •  LV emptying •  LV filling •  LV dilatation • LV stretch  contractile failure muscle •  LA pressure • LA stretch • Atrial arrhythmia (atrial fibrillation) electrics • Thrombo-embolic risk • stroke (cerebrovascular accident) • heart attack (myocardial infarct) vessels
