Ventricular arrhythmia and possible myocardial ischemia in late stage Kawasaki disease: patient with a normal coronary arteriogram.
Recent research reveals that some patients with a normal coronary arteriogram present with myocardial ischemia in the late stages of Kawasaki disease (KD). The present paper reports a patient who developed ventricular arrhythmia and possible myocardial ischemia in the late stages of KD but whose coronary arteriogram was normal. The onset of KD was at 2 years of age but cardiac involvement including coronary arterial lesion was not detected during the acute stage. At 11 years of age, the Holter electrocardiogram showed both frequent ventricular premature contractions and ventricular tachycardia. The single photon emission computed tomogram demonstrated possible myocardial ischemia. Possible myocardial ischemia was considered to be one of the causes of the ventricular arrhythmia. Although the prognosis for the majority of patients without apparent coronary arterial lesion is excellent, regular follow up must be performed on patients with a history of KD.
