The valve-in-valve technique: transcatheter treatment of aortic bioprothesis malposition.
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.
