Abstract
A method of delivering a prosthetic valve to a native mitral valve of patient's heart may include providing a radially expandable prosthetic mitral valve which has an upstream atrial portion, a downstream ventricular portion and an annular region therebetween. A constraint is removed from the ventricular portion thereby allowing radial expansion of a ventricular portion. A first anchoring tab on the ventricular portion is radially expanded and an annular region is radially expanded. An atrial skirt on the atrial flange is radially expanded after radial expansion of the ventricular portion.
