Methods for deploying a prosthetic mitral valve

A method, comprising:

• deploying an expandable prosthetic mitral valve device in a heart of a subject, by:
• deploying a first component of the prosthetic mitral valve device in a left atrium of the subject, the first component including an annulus part that is deployed at least partially in a vicinity of a native mitral annulus of the subject;
• deploying a second component of the prosthetic mitral valve in a left ventricle of the subject, the second component including a ventricular part,
• deployment of the first component and the second component being performed such that there is a gap between the ventricular part and the annulus part, the gap being configured to accommodate one or more leaflets of the native mitral valve;
• approximating the first and second components with respect to each other, such that, when the first and said second components are in an approximated configuration with respect to each other, the one or more leaflets of the native mitral valve are trapped within the gap between the ventricular part and the annulus part;
• and
• securing the annulus part and the ventricular part in the approximated configuration.
