[Transcatheter aortic valve implantation in patients with a mechanical mitral valve].

Many patients with severe aortic stenosis never undergo surgical treatment for various reasons. Apart from the standard risks, some patients face an additional problem: their carrying of a mechanical mitral valve. In these patients, transcatheter aortic valve implantation is a therapeutic option. The literature contains only few reports of this procedure being performed (usually transapically) in such patients. This paper reports the cases of 3 patients with severe aortic stenosis, all carrying a mechanical mitral valve and at high surgical risk, all of whom were implanted by transcatheter aortic valve implantation with an Edwards aortic valve prosthesis. All procedures were successful with no complications encountered.
