Role of 64-MDCT in evaluation of pulmonary atresia with ventricular septal defect.

OBJECTIVE

The purposes of this article are to describe the technical factors in performing 64-MDCT of pulmonary atresia with ventricular septal defect (PA-VSD), to describe the anatomic variations in pulmonary arterial circulation and other associated anomalies, and to describe the postoperative evaluation of this condition.

CONCLUSION

The management of this complex condition has been largely determined by the morphology of pulmonary arteries and the extracardiac sources of pulmonary blood supply. Although echocardiography and catheter angiography are the traditional imaging techniques used to diagnose PA-VSD, 64-MDCT has become a valuable noninvasive imaging technique in comprehensive evaluation of this condition.
