1. A method for anchoring an artificial mitral valve in the left atrium of the heart, said method comprising the steps of:
- deploying an artificial mitral valve in the left atrium;
positioning said valve above the annulus of the natural mitral valve; and
anchoring said artificial valve by shaping atrial wall to form an artificial annulus above said artificial valve.

Abstract
An artificial mitral valve is anchored in the left atrium by placing the valve between the annulus of the natural mitral valve and an artificial annulus. The artificial annulus is formed by inserting a tool into the coronary sinus, and adjusting the tool to force the wall of the left atrium to form an annulus above the artificial valve, this locking it in place and forming a hemostatic seal.
