- Abstract
<bold>Objectives: </bold>To analyse the diagnostic utility of flat-detector computed tomography imaging (FD-CT) in patients with congenital heart disease, including the value of image fusion to overlay three-dimensional (3D) reconstructions on fluoroscopic images during catheter-based interventions.<bold>Methods: </bold>We retrospectively analysed 62 consecutive paediatric patients in whom FD-CT was used during catheterisation of congenital heart disease. Expert operators rated the clinical value of FD-CT over conventional fluoroscopic imaging. Added radiation exposure and contrast medium volume were evaluated.<bold>Results: </bold>During a 12-month period, FD-CT was performed in 62 out of 303 cardiac catheterisations. Median patient age was 3.5 years. In 32/62 cases, FD-CT was used for diagnostic purposes, in 30/62 cases it was used in the context of interventions. Diagnostic utility was never rated as "misleading". It was classified as "not useful" in six cases (9.7%), "useful" in 18 cases (29.0%), "very useful" in 37 cases (59.7%) and "essential" in one case (1.6%). The median added dose-area product was 111.0 μGym(2), the required additional quantity of contrast medium was 1.6 ml/kg.<bold>Conclusion: </bold>FD-CT provides useful diagnostic information in most of the patients investigated for congenital heart disease. The added radiation exposure and contrast medium volume are reasonable.
