A Comparative Study Of Diagnostic Value Of Echocardiography And CTA In Complex Congenital Heart Diseases

Objective To explore the diagnostic value of multislice spiral computed tomography angiography (MSCTA) and ultrasonic cardiogram (UCG) for complex congenital heart disease(CCHD).Evaluation of UCG accuracy in diagnosis of CCHD.Methods The clinical and imaging characteristics of58cases of children with CCHD admitted from January2012to February2014were analyzed retrospectively, including32male cases and26female cases. All patients underwent UCG and MSCTA examination before operation, and the results were compared with the surgery findings. The accuracy rates of UCG and MSCTA were compared. Results A total of219heart deformities were found in58patients. For the108cardiac anomalies, the diagnostic accuracy of UCG and MSCTA were97.22%(105/108) and87.96%(95/108) respectively with a significant difference (X2=6.74, P=0.009); for111extracardiac anomalies, the diagnostic accuracy of UCG and MSCTA were90.09%(100/111) and97.30%(108/111) respectively, and difference was statistically significant (X2=4.86, P=0.027). The diagnostic accuracy of UCG and MSCTA for the total_deformities were93.61%(205/219) and92.69%(203/219),and the sensitivity were94.47%and93.54%respectively with no significant difference (X2=0.128, P=0.720). Conclusion UCG is superior to MSCTA in the diagnostic accuracy rate of cardiac deformities whereas MSCTA is more accurate than UCG for extracardiac anomalies. The Use of UCG combined with MSCTA can improve the diagnostic accuracy of CCHD.
