Abstract
The presence of severe right ventricular outflow tract calcification may preclude safe and effective transcatheter pulmonary valve replacement in patients with pulmonary allograft stenosis owing to the risk of conduit tear and suboptimal annular expansion. Debulking calcium using intravascular lithotripsy within the right ventricular outflow tract may mitigate this risk and improve valve hemodynamics. ().
摘要
严重的右心室流出道钙化的存在可能会使肺移植狭窄患者无法进行安全有效的经导管肺动脉瓣置换术，因为存在导管撕裂和瓣环扩张不理想的风险。在右心室流出道内使用血管内碎石术清除钙质可能会降低这种风险并改善瓣膜血流动力学。（）
