Abstract：
Over the last 2 decades, experience with transcatheter pulmonary valve replacement (TPVR) has grown significantly and has become an effective and reliable way of treating pulmonary valve regurgitation, right ventricular outflow (RVOT) obstruction, and dysfunctional bioprosthetic valves and conduits. With the introduction of self-expanding valves and prestents, dilated native RVOT can be addressed with the transcatheter approach. In this article, the authors review the current practices, technical challenges, and outcomes of TPVR.
摘要：
在过去的20年里，经导管肺动脉瓣置换术（TPVR）的经验已大大增加，已成为治疗肺动脉瓣反流的有效和可靠的方法，右室流出道(RVOT)梗阻,和功能失调的生物人工瓣膜和导管。随着自膨式瓣膜和支架的引入，经导管入路可以解决扩张的天然RVOT。在这篇文章中,作者回顾了目前的做法，技术挑战,和TPVR的结果。
