Patient History
A 5 day old male infant (3 kg) with an antenatal diagnosis of complex congenital heart disease was referred to CT as part of their preoperative assessment.
Acquisition
- 120 mm axial scanning without
ECG gating
- 70 kV and 149 mA using kV Assist
and 3D dose Modulation
- NI 9
- ASiR™-V1 60% - Soft algorithm - 0.35 sec rotation speed
- 6 mls of contrast media (300 mg/l)
at 1 ml/sec
- SmartPrep bolus triggering
- DLP 8.81 mGy-cm (32 cms phantom)
- CTDI 0.73 mGy
Results

“The Revolution scanner allowed us to obtain excellent imaging for preoperative assessment and planning without requiring intubation and anaesthesia,including accurate assessment of vessel diameters.”
Dr. Ruth Allen
Conclusion
The CT scan demonstrated double outlet right ventricle with
transposed great vessels (Taussig Bing variant), both atrial and ventricular septal defects and hypoplastic aortic arch with large
patent ductus arteriosus supplying the descending aorta
The infant initially underwent an atrial septostomy followed subsequently by operative treatment with coarctation repair
and pulmonary artery banding.
