Diagnosis by two-dimensional and Doppler echocardiography of coronary aneurysm in a Mexican boy with Kawasaki disease

The mucocutaneous lymph node syndrome or Kawasaki's disease, is a clinical entity consisting of high fever, mucocutaneous involvement and cervical lymphadenopathy that affects infants and young children. Although syndrome is predominantly found in Japan, it has become increasingly recognized in other countries. This disease appears to be benign and self-limited in most instances. However, extensive cardiac involvement may cause sudden death due to myocardial infarction from occlusive coronary artery disease, rupture of a coronary aneurysm or conduction abnormalities. As a result, it has become important to establish a noninvasive diagnostic method for assessing cardiac involvement in this disease. The purpose of this study is to describe the echocardiographic recognition of a left coronary artery aneurysm in a 3 years old mexican boy with Kawasaki's disease.
