What causes a fever when my child has aortic stenosis?

Many thigns: Fever is the body's response to a viral or bacterial infection. Sometimes medications can cause drug fever but an infection is more likely. Having aortic stenosis doesn't change what causes fevers. When one has a heart valve problem it just prompts quick investigation and evaluation.

Normal things: A child with aortic stenosis can get sick like anyone else. The most important thing is prolonged fever may be an indication of endocarditis (heart valve infection). If fever is persistent then blood cultures should be done.

Many Things: Fevers in children can be caused by many things. Simply having as does not make additional things potentially cause a fever. However, if your child has prolonged or unexplained fevers, then seek attention (preferably with the cardiologist) as it could be a sign of a serious (but rare) valve infection. Please discuss your specific issues with your cardiologist.
