Percutaneous aortic valve replacement is an emerging alternative to palliative medical therapy for nonsurgical patients with severe aortic valve stenosis. The impossibility of repositioning of the current transcatheter prosthesis in case of suboptimal placement is the main limit of these devices. Here, we report on a case of an 84-year-old woman successfully treated with implantation of two 18-Fr CoreValve prosthesis (CoreValve, Irvine, California), because of the suboptimal deployment of the first one, analyzing the procedural technique and the immediate and short-term clinical and hemodynamic results.
经皮主动脉瓣置换术是一种新兴的治疗方法，用于那些患有严重主动脉瓣狭窄且不适合手术的患者，可作为姑息性药物治疗的替代方案。当前经导管假体在放置不理想时无法重新定位，这是这些设备的主要局限性。在此，我们报告一例84岁女性患者，由于首次植入的18F CoreValve假体（CoreValve，加利福尼亚州欧文市）放置不理想，成功植入两枚该假体进行治疗，并分析了手术技术以及即刻和短期的临床和血流动力学结果。
