Background& Objective: Kawasaki disease is a generalized vasculitis of unknown etiology which causes
coronary artery abnormalities in 20-25 percent of untreated children.
The aim of this study was to determine the type of heart lesion and the coron
ary risk factors and to
identify patients with high risk in order to take the necessary measures to reduces morbidity and
morbidity.
Materials & Methods: We studied 70 children, aged 3 month to 10 years, who met the criteria for the
diagnosis of KD, two thirds were males.
Results: Of the (70) children who had KD , 15 cases (21.4 %) had coronary artery abnormalities ,12 cases
(17 %) had pericarditis, and 7 cases (10 %) had mitral regurgitation .The coronary artery abnormalities
were classified as follows: diffuse ectasia (5) cases 33.3%, coronary artery aneurysms 10 cases (66.6%).
small to medium-sized coronary artery aneurysms (6) cases, large sized coronary artery aneurysms (2)
cases, and giant aneurysms in (2) cases . The risk factors for coronary aneurysms were age less than 1
year or more than 5 years, male gender, fever lasting more than 10 days or recurrence of fever after an a
febrile period, lower hemoglobin, lower platelet count, higher white cell count , lower albumin level and
pericarditis. Echocardiogram follow up studied indicate coronary artery aneurysms resolve within 5 to 31
months in approximately 60% of patients where (6) aneurysms regressed spontaneously and the two large
aneurysms became smaller. One patient with giant aneurysm had developed coronary stenosis and needed
a coronary bypass surgery at the age of 9 years.
Conclusion: Coronary aneurysms were the predominant cardiac lesions in our series, most of these
aneurysms were resolved at follow up of 2-3 years.
