1. A method of implanting a prosthetic heart valve at a native atrioventricular valve region having a native valve annulus and a plurality of native leaflets, comprising:

  • delivering a prosthetic heart valve to a native valve region, the prosthetic heart valve contained within an interior of a sheath of a delivery apparatus, the prosthetic heart valve comprising an annular main body having an atrial end and a ventricular end, an atrial portion extending from the main body, and a plurality of ventricular anchors extending from the main body, each ventricular anchor being connected to the main body at only one location on the main body; and

    deploying the prosthetic heart valve from the sheath such that main body expands within the native annulus, the atrial portion is deployed in an atrium adjacent the native annulus, and the plurality of ventricular anchors extend behind the native leaflets, each ventricular anchor having a proximal end portion connected to and extending from the main body, an intermediate portion extending toward the atrial end of the main body, and a distal end portion extending from the intermediate portion, the distal end portion comprising a tissue-engaging surface that contacts the native leaflets and/or the native annulus and is wider in a circumferential direction along the tissue-engaging surface than the proximal end portion and the intermediate portion.
