Preoperative evaluation of cardiac anatomy is essential to determine the correct surgical procedure for congenital heart disease. Multi-detector row CT (MDCT) is a useful alternative imaging modality to cardiac catheterization and echocardiography. Sixteen patients (12 with total anomalous pulmonary venous return (TAPVR) and 4 with aortic arch anomalies) underwent 16-slice multi-detector row CT scanning. Three-dimensional reconstruction by MDCT was useful to determine the type of TAPVR and the presence of pulmonary venous obstruction (PVO) in TAPVR patients, as well as to detect postoperative PVO in patients who underwent intracardiac repair. In 2 patients who had asplenia associated with TAPVR III and I a, MDCT enabled an intra-atrial approach for TAPVR repair by precise preoperative determination of the relationship between the common PV chamber and single atrium . In patients with aortic arch anomalies, MDCT was useful to determine the type of anomaly, the presence of arch hypoplasia, and any associated rare vascular anomalies (including isolated subclavian artery, and the right-sided descending aorta with left aortic arch). In conclusion, MDCT provides reliable preoperative evaluation of pulmonary venous return and aortic arch anatomy, and therefore is extremely useful for surgical management of congenital heart disease.
