RESUMO
Objective:To inve tigate the value o electron beam tomography and echocardiography or diagno ing the comple congenital heart di ea e . Method :Thirty our patient with comple congenital heart di ea e underwent both echocardiography and electron beam tomography,which wa con irmed by angiocardiography in 18 patient .Twenty one patient were operated on.All data were comparatively analyzed Re ult :The rate o diagno i coincidence in diagno ing comple congenital heart di ea e wa 82 4% or electron beam tomography,and 73 5% or echocardiography.The accuracy o electron beam tomography in diagno ing e tracardiac abnormal tructure wa 97 9% and obviou ly higher than 53 2% by echocardiography.The accuracy o echocardiography in diagno ing intracardiac abnormal tructure wa 95 9% and higher than 81 6% by electron beam tomography.Electron beam tomography and echocardiography had a imilar accuracy or diagno ing abnormal tructure at the junction o ve el with cardiac chamber. Conclu ion:Electron beam tomography combined with echocardiography can greatly improve the diagno i accuracy o comple congenital heart di ea e and can al o reduce the u e o inva ive angiocardiography.
