Acute mitral regurgitation


Acute mitral regurgitation is characterized by an increase in preload and a decrease in afterload causing an increase in end-diastolic volume (EDV) and a decrease in end-systolic volume (ESV).


  1. Increase in preload
  2. Decrease in afterload
  3. Increase in end-diastolic volume
  4. Decrease in end-systolic volume

What are the Causes of Acute Mitral Regurgitation?


Ischemic MR :


  1. Papillary muscle rupture due to acute myocardial infarction
  2. Papillary muscle displacement due to MI or ischemia

Nonischemic MR


  1. Ruptured mitral chordae tendineae (flail leaflet) due to myxomatous disease (mitral valve prolapse)
  2. Infective endocarditis
  3. Blunt chest trauma
  4. Rheumatic heart disease (acute rheumatic fever
  5. Chronic rheumatic mitral valve disease
  6. Spontaneous rupture
