Dynamic observation of the echocardiographic features of coronary artery lesions in Kawasaki disease / 国际儿科学杂志

ABSTRACT

Objective To evaluate the echocardiographic features of coronary artery dilation (CAD) and coronary artery aneurysms (CAA) in Kawasaki disease dynamically.Methods Echocardiography was performed in KD cases for measurement of the diameter of the coronary artery.Results Twelve CAD and four CAA were identified in forty-one patients.In CAD group,left coronary artery (LCA) is more susceptive to dilation than right coronary artery (RCA)(P<0.05).Both LCA and RCA were involved in CAA group,the maximum diameter of coronary artery is 10mm.Six to eighteen days after treatment,LCA were regressed significantly in CAD group(P<0.05),but the diameter of RCA in CAD group and coronary artery in CAA patients have no change(P>0.05).Ten coronary artery lesion patients were followed up,8 CAD cases regressed completely,1 CAA extended,the other CAA regressed completely.Conclusions In CAD group,LCA is more susceptive to dilation than RCA,but it regressed significantly in a short time after treatment.Echocardiography is a non-traumatic method to detect the coronary artery lesions in KD patients dynamically.
