Transfemoral aortic valve implantation has emerged as a promising alternative to surgical aortic valve replacement for high-risk patients with severe symptomatic aortic stenosis. In the setting of previous mechanical mitral valve replacement, the procedure represents a challenge due to the risk of interference and subsequent functional impairment of the mechanical prosthesis. The authors report a case of successful transfemoral implantation of a selfexpandable aortic bioprosthesis in a patient with a Bj?rk-Shiley tilting-disk valve in mitral position demonstrating that the implantation is also feasible in this setting but requires careful preinterventional evaluation. Prior balloon aortic valvuloplasty with thorough observation of the mitral prosthesis during balloon inflation may be a helpful tool for indicating feasibility of this approach.
