The prosthetic heart valve may include a positional marker on a control arm. The prosthetic heart valve may include multiple positional markers on one or more control arms. The positional markers can be shapes, characters, or other symbols. The positional markers may themselves be asymmetric. The positional markers may be placed in an asymmetric location on a control arm. The control arm may be asymmetrically shaped.
