Abstract:
Objective To study the clinical value of 64-slice spiral computed tomography(64SCT) contrast-enhanced scan and three-dimensional reconstructed techniques in the diagnosis of complex congenital heart disease(CCHD). Methods 39 patients with CCHD underwent CT angiography and transthoracic echocardiograms (TTE). Of them, the electrocardiographic-gating technique was used in 8 cases. The accurate rates in diagnosing CCHD with CT, TTE and CT with or without electrocardiographic-gating were analysed compared with that of operation and χ~2 test using SPSS13.0 tool. Results A total of 102 cardiac deformities con-firmed by operations,those included 47 intracardiac deformities,the diagnostic accuracys with CT and TTE were 85.1% and 95.7%, respectively, and there was no obvious difference among them (χ~2=2.68, P>0.05). 55 extracardiac deformities, the definite diagnos-tic rates with CT and TTE were 98.2% and 78.2%, respectively. CT was superior to TTE in the indentification of extracardiac de-formities(χ~2= 14.64 ,P<0.01). There was no obvious difference between with and without electrocardiographic-gating technique during CT scanning in diagnosis of cardiac deformities(χ~2=1.84, P>0.05). Conclusion 64SCT has significant value in diagnosis of CCHD,and there was no obvious difference in diagnosis of cardiac deformities by 64SCT between with and without electrocardio-graphic-gating technic.
