Abstract:
This paper was aimed to explore the features of single ventricle with dual source computed tomography (DSCT) and the value of the modality in diagnosis of the single ventricle disease. Dual-source computed tomography imaging of 14 cases of single ventricle compared with the results of surgery and cardiac catheter were retrospectively analyzed. Firstly, 14 cases were classified into three types according to Anderson classification method, including 7 cases(50. 0%) left ventricular type, 3 cases(21. 4%) right ventricular type and 4 cases (28. 6%) undecided ventricular type. Secondly, in accompanying malformation respect, pulmonary stenosis, bilateral superior vena cava, atrial septal defect (ASD) and common atrioventricular valve were presented frequently. Thirdly, affiliated cardiac chamber of left ventricular type were mostly in front of the major cardiac chamber (5 cases,71. 4%), while affiliated cardiac chamber of right ventricular type were behind of the major cardiac chamber totally. Fourthly, more than half of aortas and pulmonary arteries stemming from common cardiac chamber can be seen (8 cases, 57. 1%). Meanwhile the aorta valves were more on the right of pulmonary valve (9 cases, 64. 3%). The classification of 10 cases of single ventricle was compared with the results of surgery, and the coincidence rate is 100%. DSCT can diagnose the single ventricle disease accurately. The aorta, pulmonary artery and coronary artery can be displayed completely and simultaneously as well.
