Living with Infective endocarditis

An infection of the inner lining of the heart chambers and valves.

Understanding Infective endocarditis

Infective endocarditis (IE) is an infection of the inner lining of the heart chambers (endocardium) and valves.

It is caused by bacteria, fungi, or other germs that get into the bloodstream and attach to the heart. It can damage the heart and cause serious complications. It can develop quickly or slowly depending on the germ and on any underlying heart problem. It can also cause problems in many other parts of the body.

Signs & symptoms

Symptoms vary from person to person. GARD says common symptoms are:

  • Fever
  • Flu-like symptoms

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include heart and blood vessel specialists.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

  4. Connect with expert centers

    Children's Cardiomyopathy Foundation may keep lists of experts for this condition.
