Proper treatment of diseases of the heart may help prevent some cases of mitral regurgitation. People with heart disease should ask their healthcare provider about taking antibiotics before dental work or surgery.
Acute mitral regurgitation may result in death if it is severe and accompanied by other medical problems. The outcome is often related to the underlying cause, such as a heart attack. People who are healthier and without other diseases do better than those with other medical problems.
Acute mitral regurgitation is not contagious and poses no risk to others.
