Use of Angiographic CT Imaging in the Cardiac Catheterization Laboratory for Congenital Heart Disease

摘要: Objectives This study sought to retrospectively evaluate our initial experience using angiographic computed tomography (ACT) in a pediatric cardiac catheterization laboratory. Background ACT provides cross-sectional CT images from rotational angiography run C-arm mounted flat-panel detector the interventional suite. A 3-dimensional (3D) image can be created volume set and used real time during procedure. To knowledge, its use has never previously been described for congenital heart disease. Methods 3D reconstructions were we reviewed cases first year of use. Images obtained independently evaluated determine their diagnostic utility. Radiation dose reduction protocols defined phantom testing radiation calculation. Results was 41 catheterizations patients at median age 5.1 years (range: 0.4 58.8 years) evaluation of: right ventricular outflow tract (RVOT)/central pulmonary arteries (PAs) 20; cavopulmonary connection (CPC) 11; veins 5; distal PAs 4; other locations 5. Four subjects had 2 anatomic areas studied by ACT. The mean contrast 1.2 ± ml/kg. Diagnostic-quality imaging 71% cases: 13/20 RVOT/central PAs; 9/11 CPC; 4/5 veins; 2/4 others. In 12 cases, contributed clinical outcomes beyond standard angiography. allowed comparable exposure biplane cineangiogram. Conclusions without significant increase or exposure. certain additional detail may aid complex catheter manipulations. Future work is needed continue define applications this new technology.
