Transvenous Implantation of a Stent Valve for Calcified Native Mitral Stenosis.

We used a modified combination of the transseptal and transapical methods to facilitate the controlled delivery and use of a stent valve in a patient with calcified native mitral stenosis. A loop from the right femoral vein passing transseptally and then through the apex of the left ventricle was created, enabling highly controlled positioning and deployment of the stent valve.
