Overview
Mitral regurgitation (MR) can be classified as either acute or chronic according to the acuity of the events leading to the valvular abnormality. Chronic MR is further classified as primary or secondary based on the presence or absence of one or more abnormalities in the structures of the valves, respectively. Secondary MR can be either ischemic or functional.
Classification
- Mitral regurgitation (MR) can be classified as either acute or chronic according to the acuity of the events leading to the valvular abnormality.
- Chronic MR is further classified as primary or secondary based on the presence or absence of one or more abnormalities in the structures of the valves, respectively.
- Secondary MR can be either ischemic or functional.[1][2][3][4]
Mitral Regurgitation (MR) Acute MR Chronic MR Primary MR Due to the disruption of at least one of the valvular structures as a result of any of the following:
- Myxomatous degeneration (young patients)
- Fibroelastic deficiency disease (old patients)
- Myxomatous degeneration (young patients)
Secondary MR
Due to a functional abnormality with a preserved normal structure of the mitral valve as a result of left ventricular dysfunction as seen in:
- Coronary artery disease (ischemic MR)
- Any condition leading to left ventricular dysfunction (functional MR)
