Paravalvular leakage (PVL) occurs in 6%-15% of cases after surgical heart valve replacement. A percutaneous approach is increasingly used to close PVLs as an alternative to repeat surgery. Computed tomography (CT) can be used for simulation of fluoroscopic cardiac anatomy. This technique allows preprocedural definition of optimal C-arm angulations and PVL localization in reference to fluoroscopic views. It is very helpful for guidewire crossing of the PVL and positioning of the closure device. We report a case with the first use of dedicated software for fluoroscopic simulation (FluoroCT) in transcatheter mitral PVL closure.
人工瓣膜周漏（PVL）在心脏瓣膜置换术后的病例中发生率为6% - 15%。经皮途径越来越多地用于闭合PVL，作为再次手术的替代方法。计算机断层扫描（CT）可用于模拟荧光透视下的心脏解剖结构。该技术允许在术前根据荧光透视视图确定最佳C形臂角度并定位PVL。这对于引导钢丝穿过PVL以及定位闭合装置非常有帮助。我们报告了一例在经导管二尖瓣PVL闭合术中首次使用专用荧光透视模拟软件（FluoroCT）的病例。
