Mitral regurgitation - chronic Health Article

Complications

• Arrhythmias (abnormal heart rhythms), including atrial fibrillation and lethal arrhythmias
• Clots to other areas
• Endocarditis (infection of the heart valve)
• Heart failure
• Pulmonary emboli (blood clots in the lungs)
• Stroke

Calling your health care provider

Call your health care provider if you have symptoms of mitral valve regurgitation, or if symptoms worsen or do not improve with treatment.

Also call your health care provider if you are being treated for this condition and develop signs of infection, which include:

• Chills
• Fever
• General ill feeling
• Headache
• Muscle aches

Prevention

Treat strep infections promptly to prevent rheumatic fever. Prompt treatment of disorders that can cause mitral regurgitation reduces your risk.

Any invasive procedure, including dental work and cleaning, can introduce bacteria into your bloodstream. The bacteria can infect a damaged mitral valve, causing endocarditis. Always tell your health care provider and dentist if you have a history of heart valve disease or congenital heart disease before treatment. Taking antibiotics before dental or other invasive procedures may decrease your risk of endocarditis.
