To quantify radiation exposure during pediatric cardiac catheterizations performed by multiple operators on a new imaging platform, the Artis Q.zen (Siemens Healthcare, Forchheim, Germany), and to compare these data to contemporary benchmark values.
The Artis Q.zen has been shown to achieve significant radiation reduction during select types of pediatric cardiac catheterizations in small single-center studies. No large multicenter study exists quantifying patient dose exposure for a broad spectrum of procedures.
Retrospective collection of Air Kerma (AK) and dose area product (DAP) for all pediatric cardiac catheterizations performed on this new imaging platform at four institutions over a two-year time period.
A total of 1,127 pediatric cardiac catheterizations were analyzed. Compared to dose data from earlier generation Artis Zee imaging systems, this study demonstrates 70-80% dose reduction (AK and DAP) for similar patient and procedure types. Compared to contemporary benchmark data for common interventional procedures, this study demonstrates an average percent reduction in AK and DAP from the lowest dose saving per intervention of 39% for AK and 27% for DAP for transcatheter pulmonary valve implantation up to 77% reduction in AK and 70% reduction in DAP for atrial septal defect closure.
Use of next-generation imaging platforms for pediatric cardiac catheterizations can substantially decrease patient radiation exposure. This multicenter study defines new low-dose radiation measures achievable on a novel imaging system.
量化多位操作人员在新成像平台 Artis Q.zen（德国西门子医疗公司，Forchheim）上进行儿科心导管术时的辐射暴露，并将这些数据与当代基准值进行比较。
Artis Q.zen 已在小型单中心研究中显示，在某些类型的儿科心导管术中能显著降低辐射。目前尚无大型多中心研究对广泛的手术程序进行患者剂量暴露的量化。
回顾性收集在四家机构的两年时间内，在新成像平台上进行的所有儿科心导管术的空气比释动能（AK）和剂量面积乘积（DAP）数据。
共分析了 1127 例儿科心导管术。与早期的 Artis Zee 成像系统的剂量数据相比，本研究表明，对于类似的患者和手术类型，剂量降低了 70-80%（AK 和 DAP）。与常见介入性手术的当代基准数据相比，本研究表明，从经皮肺动脉瓣植入术的 AK 每干预降低 39%和 DAP 降低 27%到房间隔缺损封堵术的 AK 降低 77%和 DAP 降低 70%，平均 AK 和 DAP 降低幅度为 39%。
在儿科心导管术中使用下一代成像平台可以显著降低患者的辐射暴露。这项多中心研究定义了在新型成像系统上实现的新的低剂量辐射测量。
