Transcatheter pulmonary valve replacement (TPVR) is now common practice in patients with significant pulmonary regurgitation (PR), stenosis (PS), or mixed pulmonary valve disease. While the Melody valve (Medtronic, Inc.) and its delivery system were specifically designed for use in the right ventricular outflow tract (RVOT), Sapien valves (XT and S3, Edwards Lifesciences, Inc.) and their delivery systems (Novaflex and Commander) were not. As a result, placement of Sapien valves in the RVOT can be challenging secondary to the stiffness of the current delivery system. Manipulating a stiff delivery system within the RV also introduces risk to the tricuspid valve and its chordal attachments. We report a novel delivery technique for the Sapien S3 valve which has greatly simplified valve delivery into the RVOT and may potentially reduce the risk of tricuspid valve injury.
经导管肺动脉瓣置换术（TPVR）现已广泛应用于存在严重肺动脉瓣反流（PR）、狭窄（PS）或混合性肺动脉瓣疾病的患者。虽然 Melody 瓣膜（美敦力公司）及其输送系统是专门为右心室流出道（RVOT）设计的，但 Sapien 瓣膜（XT 和 S3，爱德华兹生命科学公司）及其输送系统（Novaflex 和 Commander）并非如此。因此，由于现有输送系统的僵硬，Sapien 瓣膜在 RVOT 中的放置可能具有挑战性。在 RV 内操纵僵硬的输送系统也会给三尖瓣及其腱索附着带来风险。我们报告了一种 Sapien S3 瓣膜的新型输送技术，该技术极大地简化了瓣膜输送至 RVOT 的过程，并且可能降低三尖瓣损伤的风险。
