Abstract：
A 44-year-old man with history of D-transposition of the great arteries status post Mustard repair with pulmonary baffle obstruction was referred for further management. Cardiac computed tomography demonstrated calcific stenosis of the pulmonary venous baffle (PVB) outflow and right heart catheterization demonstrated elevated superior vena cava, pulmonary artery, and pulmonary capillary wedge pressures. A course of treatment is described demonstrating the challenges and potential complications of hybrid PVB stenting in a patient with challenging anatomy.
摘要：
一名44岁的男子，有芥末酱修复后大动脉D转位的病史，并伴有肺挡板阻塞，被转诊为进一步治疗。心脏计算机断层扫描显示肺静脉挡板（PVB）流出道钙化狭窄，右心导管检查显示上腔静脉升高，肺动脉,和肺毛细血管楔压。描述了治疗过程，证明了在具有挑战性解剖结构的患者中混合PVB支架置入的挑战和潜在并发症。
