Incomplete Kawasaki Disease Manifesting As Transient Heart Failure In A Previously Healthy Adolescent

Kawasaki disease (KD) is a mucocutaneous lymph node syndrome with important cardiovascular complications which usually afflicts young children. We describe a 16-year-old woman who developed transient heart failure during the acute phase of incomplete KD. The diagnosis was based on the development of coronary aneurysms during heart failure and 2 criteria of the disease. Incomplete KD is a cause, albeit rare, of myocardial dysfunction in human adolescents. Healthcare providers should therefore be aware of the possibility of incomplete KD in patients with heart failure during the course of an acute febrile illness associated with mucocutaneous changes.
