A method for treating a diseased native valve in a patient includes advancing a distal end of a delivery device that is detachable coupled to an anchor to a first side of a native valve, deploying the anchor from a delivery configuration to a deployed configuration on the first side of the native valve, advancing the anchor in the deployed configuration from the first side of the native valve to a second side of the native valve such that the anchor is located only on the second side of the native valve, rotating the anchor in the deployed configuration around chordae of the native valve, confirming a position of the anchor with an imaging source, and releasing the anchor from the distal end of the delivery device.
