Evaluation of Myocardial Ischemia of Kawasaki Disease at Convalescence Period by Radioactive Nuclide Myocardial Perfusion Imaging / 实用儿科临床杂志

ABSTRACT

Objective To discuss the clinical value of 99Tcm-sestamibi(99Tcm-MIBI) myocardial perfusion imaging on detecting myocardial ischemia in children with Kawasaki disease(KD) at convalescence period.Methods Twenty-one children wih KD at convalescence period were divided into 2 groups according to results of echocardiography.Four cases with coronary artery dilation,17 cases without coronary artery dilation.All cases accepted dipyridamole stress myocardial perfusion imaging.These patients who had positive results were given rest myocardial perfusion imaging again next day.Results Among 21 cases,9 cases(42.8%) were positive in perfusion imaging.Four cases with coronary artery dilation showed myocardial ischemia in different degree detected by myocardial perfusion imaging.Among 17 cases without coronary artery dilation,5 cases(29.4%) were positive.Conclusions Compared to echocardiography,99Tcm-MIBI myocardial perfusion imaging can objectively evaluate the location,extent and degree of myocardial ischemia of children with KD.It will be a routine test in observing its phase development.
