摘要：
A heart valve prosthesis and methods of its implantation are described herein. The prosthesis can be implanted in a heart of a patient by positioning an upper support of an anchoring element into a left atrium of the patient. The upper support can expand adjacent to a native valve structure of the patient. Further, the upper support can be moved against the native valve structure in a direction toward a left ventricle of the patient. A lower support of the anchoring element can be positioned into the left ventricle, spaced apart from the upper support, the lower support being separate from the upper support and coupled to the upper support by a flexible connector. Finally, the lower support can expand within the left ventricle, and engagement members of the lower support can engage with tissue of the native valve structure.
