Transcatheter aortic valve replacement (TAVR) is not the preferred therapy for pure aortic regurgitation (AR). Extremely horizontal aorta (aorta root angle ≥70°) is regarded as an "off-label" use in self-expanding TAVR. This case series enrolled 7 consecutive pure AR patients who had extremely horizontal aorta and underwent self-expanding TAVR from the TORCH registry. To the best of our knowledge, this is the first study to report successful self-expanding TAVR for pure AR with extremely horizontal aorta, revealing the feasibility of both transapical and transfemoral TAVR in this challenging population.
经导管主动脉瓣置换术（TAVR）并非单纯主动脉瓣反流（AR）的首选治疗方法。极水平主动脉（主动脉根部角度≥70°）在自膨胀式TAVR中被视为“非适应证”应用。本病例系列纳入了7例连续的单纯AR患者，这些患者有极水平主动脉，并从TORCH注册研究中接受了自膨胀式TAVR。据我们所知，这是第一项报告成功地对有极水平主动脉的单纯AR进行自膨胀式TAVR的研究，揭示了经心尖和经股动脉TAVR在这一具有挑战性的人群中的可行性。
