Abstract Objective: To explore diagnostic value of the spiral CT in the diagnosis of congenital heart disease with pulmonary atresia. Methods: Sixteen patients with pulmonary atresia associated with ventricular septal defect were enrolled in this study. All of them had X-ray plain film, 256-slice spiral CT and echocardiography. And all the imaging data were analyzed retrospectively. Results: All patients obtained correct diagnosis by spiral CT, and many associated malformations were also found. All patients in this study group complicated with ventricular septal defect, 15 of them with overriding aorta, twelve cases were found to have obvious major aorto-pulmonary collateral arteries and five patients associated with right aortic arch and descendding aorta, 4 patients had patent ductus arteriosus. Three patients were found to have developmental abnormalities of brachiocephalic artery, 7 cases had varying developmental abnormalities of main pulmonary artery. Only one case appeared to have atrial septal defect. In 5 cases Mcgoon index was >1.2, 4 patients’ Nakata index >150 mm2/m2. Conclusion: Application of multislice CT has a high diagnostic accuracy rate for congenital heart disease with pulmonary atresia and ventricular septal defect, particularly in the diagnosis of aorto-pulmonary collateral arteries.
