Papillary muscle position control devices, systems, and methods are provided. A papillary muscle position control device generally includes a first anchor, a second anchor, and a support structure. The first anchor can be configured to fixedly connect to an in-situ valve of a heart ventricle. The second anchor can be configured to fixedly connect to a muscle wall of the valve. The support structure can be configured to have an adjustable length and be coupled to the first anchor and second anchor such that adjusting the length of the support structure varies a distance between the first anchor and the second anchor.
