| Abstract: | Thirty-three children with acute rheumatic fever were studied using echocardiography to characterize heart involvement in this disease. Among 26 subjects with a first episode of acute rheumatic fever, 18 had a clinical diagnosis of carditis and six had heart failure. Heart failure usually resulted from valvular incompetence rather than from myocardial failure in these patients. Conversely, among seven subjects with recurrent rheumatic fever, five had a clinical diagnosis of carditis and four had heart failure. Severe left ventricular dysfunction noted on echocardiography probably contributed significantly to the appearance of heart failure in two of these four subjects. Ten patients were initially believed not to have carditis: a diagnosis of mitral valvulitis was made in two of these ten on the basis of the results of the echocardiographic examination. Echocardiography, which provides important information on the cardiac status of patients with acute rheumatic fever, may help in assessing the prognosis and may be useful in the therapy of these patients. |
