During percutaneous pulmonary valve implantation, it is challenging to advance the delivery system loaded with a stent-valve through the right ventricular outflow tract. An extra-stiff wire can provide enough supporting and stable positioning to prevent the displacement of the guide wire in stent-valve delivery. In the 2 cases reported here, we used a snare to trap the extra-stiff wire and a large sheath to support the snare; thus, the extra-stiff wire was pulled to the distal end and provided strong support for the advancement of the delivery system. After 8 months of follow-up, the patients were in good condition with excellent valve function. We named this novel, efficient technique the "parallel anchor sheath snare" technique. This report highlights a novel delivery strategy for patients with tortuous right ventricular outflow tracts in percutaneous pulmonary valve implantation.
在经皮肺动脉瓣植入术中，将装载支架瓣膜的输送系统通过右心室流出道推进极具挑战性。超硬导丝能够提供足够的支撑力和稳定的定位，防止支架瓣膜输送过程中导丝移位。本文报告的 2 例患者中，我们使用圈套器套住超硬导丝，并用大鞘管支撑圈套器，从而将超硬导丝拉至输送系统的远端，为其推进提供有力支撑。8 个月的随访结果显示，患者情况良好，瓣膜功能良好。我们将这一新颖有效的技术命名为“平行锚定鞘管圈套器”技术。本研究旨在为经皮肺动脉瓣植入术中右心室流出道迂曲患者提供一种新的输送策略。
