[Non-dilated coronary artery lesion and myocardial perfusion in children with Kawasaki disease: analysis of 43 cases].

Objective: The study was designed to investigate the impact of non-dilated coronary artery wall lesion on myocardial perfusion.

Methods: Doppler tissue image (DTI) was used to measure regional ventricular wall motion in 43 Kawasaki children with non-dilated coronary arterial wall echocardiographic abnormalities (rough intima and arterial wall thickening) detected by two-dimensional echocardiography (2DE) at acute phase. A total of 31 cases who had both non-dilated coronary lesion and lowered ventricular wall motion velocity at subacute and convalescence phase underwent submaximal exercise single photon emitting computerized tomography (SPECT) for the evaluation of myocardial perfusion.
