1. A method for use at a native valve of a heart of a subject, the native valve including chordae tendineae and native leaflets, the method comprising:
- transcatheterally advancing, toward the native valve, a prosthetic valve structure in a collapsed state thereof, the prosthetic valve structure including prosthetic leaflets, an annular portion, and curved anchors;
positioning the annular portion of the prosthetic valve structure between the native leaflets; and
subsequently, securing the prosthetic valve structure to the native valve by rotating the prosthetic valve structure in a manner that causes the anchors of the prosthetic valve structure to gather the chordae tendineae between the anchors and the annular portion.

Abstract
A prosthetic valve structure, in a collapsed state thereof, is transcatheterally advanced toward a native valve of a subject, the native valve including native leaflets, and the prosthetic valve structure including prosthetic leaflets. An annular portion of the prosthetic valve structure is positioned between the native leaflets. Subsequently, the prosthetic valve structure is rotated such that curved anchors of the prosthetic valve structure gather the native chordae tendineae of the heart between the anchors and the annular portion.

8. A method for use at a native valve of a heart of a subject, the native valve including chordae tendineae and native leaflets, the method comprising:
-
transcatheterally advancing, toward the native valve, a prosthetic valve structure in a collapsed state thereof, the prosthetic valve structure including prosthetic leaflets, an annular portion, and curved anchors that point in a circumferential direction around the annular portion; positioning the annular portion of the prosthetic valve structure between the native leaflets; and subsequently, rotating the prosthetic valve structure in the circumferential direction such that the curved anchors of the prosthetic valve structure gather the chordae tendineae of the heart between the anchors and the annular portion. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A method for use at a native valve of a heart of a subject, the native valve including chordae tendineae and native leaflets, the method comprising:
-
transcatheterally advancing, toward the native valve, a prosthetic valve structure in a collapsed state thereof, the prosthetic valve structure including prosthetic leaflets, an annular portion, and anchors, each of the anchors having a respective leading tip; positioning the annular portion of the prosthetic valve structure between the native leaflets; and subsequently, rotating the prosthetic valve structure in a manner that causes the anchors to gather the chordae tendineae between the anchors and the annular portion by the anchors moving, leading tip first, behind the chordae tendineae. - View Dependent Claims (16, 17, 18, 19, 20, 21)
