Pulmonary atresia with double ductus arteriosus.

We present the case of a neonate with pulmonary atresia and persistent bilateral patent ductus arteriosus imaged by gated multidetector CT. Traditionally, these patients have been assessed preoperatively with invasive angiocardiography or with cardiovascular magnetic resonance under sedation. Our case illustrates that contemporary cardiovascular CT techniques can now be used for preoperative evaluation with minimal radiation penalty, obviating the risks of sedation or cardiac catheterization.
