A system for delivering a prosthetic valve to a native mitral valve of patient's heart, the native mitral valve having a native anterior leaflet and a native posterior leaflet, the system comprising: a prosthetic valve comprising: a ventricular portion (610; 710; 810) comprising a ventricular skirt (628; 728; 828), an anterior anchoring tab (624; 724; 824) disposed on the ventricular skirt (628; 728; 828), and a posterior anchoring tab (630; 730; 830) disposed on the ventricular skirt (628; 728; 828); and an atrial portion (606; 706; 806) comprising an atrial flange, wherein the ventricular portion (606; 706; 806) is configured to radially expand first, and wherein the atrial portion (606; 706; 806) is configured to radially expand after the ventricular portion (606; 706; 806); a delivery system wherein the prosthetic valve is coupled to a distal portion of the delivery system, wherein actuation of the distal portion of the delivery system unconstrains the prosthetic valve, to allow radial expansion of the ventricular portion (606; 706; 806) first, and radial expansion of the atrial portion after the ventricular portion (606; 706; 806); wherein the anterior anchoring tab (624; 724; 824) and posterior anchoring tab (630; 730; 830) each comprise at least one elbow, wherein the prosthetic valve further comprises at least one commissure tab (712; 812), the distal portion of the delivery system further comprises a capsule and an elongate shaft, the capsule comprising a distal portion and a proximal portion and, the elongate shaft comprising a commissure control element and an elbow control element, wherein the commissure control element and elbow control element are disposed inside the capsule, wherein the at least one elbow is coupled to the elbow control element, and the at least one commissure tab (712; 812) is coupled to the commissure control element, and wherein actuation of the distal portion of the delivery system is configured to separate the proximal portion of the capsule away from the distal portion of the capsule, thereby removing a constraint therefrom. a prosthetic valve comprising: a ventricular portion (610; 710; 810) comprising a ventricular skirt (628; 728; 828), an anterior anchoring tab (624; 724; 824) disposed on the ventricular skirt (628; 728; 828), and a posterior anchoring tab (630; 730; 830) disposed on the ventricular skirt (628; 728; 828); and an atrial portion (606; 706; 806) comprising an atrial flange, wherein the ventricular portion (606; 706; 806) is configured to radially expand first, and wherein the atrial portion (606; 706; 806) is configured to radially expand after the ventricular portion (606; 706; 806); a ventricular portion (610; 710; 810) comprising a ventricular skirt (628; 728; 828), an anterior anchoring tab (624; 724; 824) disposed on the ventricular skirt (628; 728; 828), and a posterior anchoring tab (630; 730; 830) disposed on the ventricular skirt (628; 728; 828); and an atrial portion (606; 706; 806) comprising an atrial flange, wherein the ventricular portion (606; 706; 806) is configured to radially expand first, and wherein the atrial portion (606; 706; 806) is configured to radially expand after the ventricular portion (606; 706; 806); a delivery system wherein the prosthetic valve is coupled to a distal portion of the delivery system, wherein actuation of the distal portion of the delivery system unconstrains the prosthetic valve, to allow radial expansion of the ventricular portion (606; 706; 806) first, and radial expansion of the atrial portion after the ventricular portion (606; 706; 806); wherein the anterior anchoring tab (624; 724; 824) and posterior anchoring tab (630; 730; 830) each comprise at least one elbow, wherein the prosthetic valve further comprises at least one commissure tab (712; 812), the distal portion of the delivery system further comprises a capsule and an elongate shaft, the capsule comprising a distal portion and a proximal portion and, the elongate shaft comprising a commissure control element and an elbow control element, wherein the commissure control element and elbow control element are disposed inside the capsule, wherein the at least one elbow is coupled to the elbow control element, and the at least one commissure tab (712; 812) is coupled to the commissure control element, and wherein actuation of the distal portion of the delivery system is configured to separate the proximal portion of the capsule away from the distal portion of the capsule, thereby removing a constraint therefrom.
