Transthoracic echocardiography vs 64-slice spiral computed tomography in diagnosis of complex congenital heart disease / 中华超声影像学杂志

ABSTRACT

Objective To explore the value of transthoracic echocardiography(TTE) and 64-slice spiral computed tomography(CT) in the diagnosis of complex congenital heart disease(CHD). Methods Ninety-seven patients diagnosed as CHD by TTE underwent 64-slice spiral CT for cardiovascular examination. The results were compared with the results by cardiovascular angiography and from surgery. Results The total diagnosis accordance rated by TEE was 90. 2% and that by spiral CT was 92.5%. There was no difference in diagnosis accuracy rate between TTE and spiral CT. The diagnosis accuracy rate in intracardiae defomities by TTE was 99.2 %, higher than 87.50% by spiral CT. However, the diagnosis accuracy rate in extracardiac defomities and ventricular-arterial connections was 99. 0% by spiral CT, higher than 78. 6% by TTE. The combination of TTE and spiral CT can raise the diagnosis accuracy rate to 99. 1%. Conclusions TTE is of significant value in complex CHD diagnosis,especially in the diagnosis of intracardiac defomities. The combination of TTE and spiral CT can raise the diagnosis accuracy rate of various kinds of complex CHD.
