Abstract
Objective: To explore the clinical value of the 256-slice multi-detector computed tomography in the diagnosis of complex congenital heart disease in children. Methods: Datas of 69 patients under 14 years old with complex congenital heart disease, who underwent both computed tomography angiography(CTA) and transthoracic echocardiography(TTE) as preoperative examinations in our hospital from August 2009 to May 2011 were collected. All the patients were proved by operation. Results: As to cardiac abnormalities, the diagnostic accuracy rates of CT and TTE were 91.3% and 98.8% respectively, but the difference was not statistically significant(P=0.07). As to malformations of atrial ventricular great vessals connection, the diagnostic accuracy rates of CT and TTE were 95.7% and 97.8% respectively, but the difference was not statistically significant(P=1.0). As to large extracardiovascular malformation, the diagnostic accuracy rates of CT and TTE were 97.3% and 84% respectively, and the difference was statistically significant(P=0.012). Conclusion: The diagnostic accuracy rate of the 256-slice CT in the diagnosis of complex congenital heart disease is high, especilally in the diagnosis of large extracardiovascular malformation, with an accuracy rate of 97.3%, better than TTE.
