1. A prosthetic device for implanting at a native mitral or tricuspid valve region of the heart, the native valve region having a native valve annulus and native leaflets, the prosthetic device comprising:

  • a main body configured for placement within the native valve annulus, the main body having a lumen extending between an atrial end and a ventricular end and a longitudinal axis extending from the atrial end to the ventricular end;

    an atrial cap that extends radially outwardly from the atrial end; and

    a plurality of ventricular anchors spaced angularly around a circumference of the main body, each ventricular anchor having a proximal end portion connected to the main body proximate the ventricular end at only one location on the main body, an intermediate portion extending away from the atrial end and then back toward the atrial end so as to define a first bend, and a distal end portion extending from the intermediate portion, the distal end portion comprising a first section, and a second section, the first section extending from the intermediate portion alongside the main body between the atrial end and the ventricular end in a direction toward the atrial end and radially away from the main body at a first angle relative to the longitudinal axis starting at the intermediate portion and moving toward the second section of the distal end portion, the second section extending from the first section in a direction radially away from the main body at a second angle relative to the longitudinal axis starting at the first section and moving toward a distal end of the second section, the second angle being greater than the first angle, the second section comprising a tissue-engaging surface facing the atrial end that can contact the native annulus and/or the native leaflets, the second section being wider in a circumferential direction along the tissue-engaging surface than the proximal end portion and the intermediate end portion.
