ABSTRACT
Objective To probe the clinical application of CT in the diagnosis of criss-cross heart(CCH).Methods Five patients with CCH confirmed by operation were retrospectively analyzed.Enhanced 64-slice spiral CT was performed in 2 patients and enhanced single-slice electron beam CT was performed in 3 patients.Three dimensional reconstructions were applied for the fully display of anatomic malformations,and the results were compared with that of echocardiogram and angiocardiogram with Chi-square test Results(1)Visceroatrial situs solitus,twisted and concordant atrioventricular connection,horizontally oriented ventricular septum,ventricular septum defect and pulmonary stenosis were found in all patients on CT.The ventriculoarterial connection was discordant,including double-outlet right ventricle in 4 patients and complete transposition of great arteries in 1 patient In addition,associated anomalies including persistent left superior vena cava(n=2),coarctation of the aorta(n=1)and right aortic arch with right descending aorta(n=1)were detected as well.(2)Total 33 anomalies in 5 cases were found during operation.The diagnostic accuracy of CT,angiocardiogram and echocardiogram was 93.9%(31/33),81.8%(27/33)and 54.5%(18/33)respectively.There was a significant difference between CT and echocardiogram(X~2=13.39,P<0.01),and no significant difference between CT and angiocardiogram(X~2=1.29,P>0.05).Conclusion CT is an excellent imaging technique for the diagnosis of CCH.
