Cardiovascular manifestations in Kawasaki disease.

Thirteen patients with Kawasaki disease were reviewed. The average age at presentation was 31 months (range: 6 weeks to 8 years). Mean follow up was 36 months, with a range of 5 to 53 months. Cardiovascular manifestations were present in 9 patients. These comprised pericarditis with myocarditis (2), pericardial effusion (4), coronary artery ectasia (3), coronary artery aneurysms (3), peripheral artery aneurysm (1) and peripheral vasculitis (1). Treatment consisted of aspirin alone in 11 and gammaglobulin with aspirin in 2 patients. One patient with coronary artery involvement died following a myocardial infarction. A large coronary artery aneurysm persists, 31 months after initial detection in another patient. Spontaneous resolution of the cardiovascular complications occurred in the remaining seven patients. The importance of clinical awareness and detailed evaluation and follow up of the cardiovascular system in Kawasaki disease is emphasised. There is also a need, however, to exclude other diagnoses which may have a similar clinical presentation.
