RESUMEN
This study was performed to assess the accuracy of pulsed Doppler echocardiographic(PDE) diagnosis of ventricular septal defect(VSD). 119 children with congenital heart disease, aged 9 months to 17 years, admitted to our hospital for cardiac surgery, were studied. These children had VSD(56), ASD(18), PDA(43), PS(1) and Cortriatrium(1). A specific PDE diagnosis of VSD can be made by following the turbulent VSD jet(TVJ) through the septum, and a PDE diagnosis of VSD was made in 53 out of 56 patients(95%) proven by catheterization and operation. There were two false positive PDE diagnosis of VSD by PDE, were proven to be perimembranous VSD at operation, and 3 children who were classified into subarterial infundibular VSD by PDE, were proven to be perimembranous VSD at operation. PDE seems to be a very useful tool in preoperative evaluation of VSD.
