1. A method of delivering a prosthetic mitral valve comprising:

  • delivering a distal anchor from a delivery sheath such that the distal anchor self-expands to a fully expanded configuration inside a ventricular heart chamber on a first side of the mitral valve annulus;

    proximally moving the distal anchor by retracting a delivery device to cause the distal anchor to self-align within the mitral valve annulus and directly contact tissue of the ventricular heart chamber; and

    delivering a proximal anchor from the delivery sheath to an atrial heart chamber on a second side of the mitral valve annulus so that the proximal anchor self-expands to a fully expanded configuration, wherein the proximal anchor self-expansion causes the proximal anchor to move towards the distal anchor, directly contact tissue of the atrial heart chamber, and capture tissue of the mitral valve annulus between the proximal and distal anchor, and wherein in the fully expanded configuration the proximal anchor is 10 mm or less from the self-expanded distal anchor and is substantially parallel with the fully expanded configuration of the distal anchor.
