Transcatheter aortic valve replacement is a less invasive alternative for high-risk patients. However, valve embolization is a rare but dreaded complication. We report the successful off-pump retrieval of an embolized valve after transfemoral transcatheter aortic valve replacement through a left anterior thoracotomy. We maintained the embolized valve on the guidewire and snared it using a transapical approach. We then deployed a valve in an adequate position to ensure hemodynamic stability before transapical removal of the embolized valve. Transapical exteriorization of the femoral guidewire offers additional support, particularly in patients with a horizontal aortic annulus.
经导管主动脉瓣置换术是高危患者的一种侵入性较小的替代治疗方法。然而,瓣膜栓塞是一种罕见但可怕的并发症。我们报告了1例经股动脉经导管主动脉瓣置换术后通过左前开胸术成功在体外循环下取出栓塞瓣膜的病例。我们将栓塞瓣膜固定在导丝上,并通过经心尖途径将其套住。然后,在经心尖取出栓塞瓣膜之前,我们将一个瓣膜放置在适当位置以确保血流动力学稳定。股动脉导丝经心尖引出可提供额外支持,特别是对于主动脉瓣环呈水平位的患者。
