We describe the use of low-dose dual-source cardiac for the evaluation of a neonate with suspected total anomalous pulmonary venous connection. This novel technique obviates the need for sedation or breathholding. Radiation dose-reduction strategies result in sub-mSv-estimated effective doses, substantially lower than annual background radiation dose. Low-dose, high-pitch cardiac CT should be considered as an alternative to MRI or diagnostic cardiac catheterisation in neonates with complex CHD, requiring definitive anatomic evaluation.
