Abstract

New technology advances in transcatheter aortic valve implantation (TAVI) promise to improve outcomes and usability. The next generation Direct Flow Medical (DFM) valve is a non metallic, repositionable and retrievable bioprosthesis with a flexible system that provides an optimal circumferential seal. We report a case of TAVI complicated by massive aortic regurgitation after balloon aortic predilation. This case demonstrates that the design and delivery mode of the DFM valve is advantageous during this emergency situation.

摘要

经导管主动脉瓣植入术（TAVI）的新技术进展有望改善治疗效果和易用性。下一代Direct Flow Medical（DFM）瓣膜是一种非金属、可重新定位和可回收的生物假体，具有灵活的系统，可提供最佳的圆周密封。我们报告一例经皮球囊主动脉预扩张后发生大量主动脉瓣反流的TAVI病例。该病例表明，在这种紧急情况下，DFM瓣膜的设计和输送方式具有优势。
