摘要：
An anchoring element for a heart valve prosthesis can include an upper support, a lower support, and a flexible connector. The upper support is configured to be positioned adjacent to a native valve structure of a patient. The upper support can include an anterior portion and a posterior portion. The lower support is separate from the upper support and can be configured to engage the native valve structure from a ventricular side. The lower support can include at least two engagement members. The flexible connector includes an upper end portion coupled to the upper support and a lower end portion coupled to the lower support. The lower support and the upper support are radially expandable from a collapsed configuration to an expanded configuration for delivery within the patient to treat a valve disorder.
