Myocarditis and coronary dilatation in the 1st week of life: neonatal incomplete Kawasaki disease?
Acute heart failure in the early neonatal period is rare. Normally it is due to asphyxia, severe septicaemia, a congenital heart malformation or a viral myocarditis. Kawasaki disease (KD) as a cause of an neonatal myocarditis is not an established diagnosis. KD is a vasculitis of still unknown origin occurring predominantly in infants and preschool children. KD before the age of 3 months is rare. There are only few reports about KD in the 1st month. We present a newborn who showed the cardiac symptoms of KD in the 1st week of life with coronary dilatation and myocarditis.


CONCLUSIONS
The diagnosis of incomplete KD should be considered not only in infants but also in newborns with signs of myocarditis and coronary abnormalities. Therapy with gammaglobulins may prevent the sequelae of coronary involvement.
