1. A system comprising:
a processor; and
non-transitory computer-readable medium with instructions thereon, that when executed by the processor, cause the system to:
determine a curvature of a transseptal needle based at least in part on a spatial relationship between an access vessel and a target puncture location and a predetermined needle shape;
determine a deployed position of the predetermined needle shape such that a proximal point of the predetermined needle shape is positioned at the access vessel and a distal point of the predetermined needle shape is positioned at an interatrial septum; and
determine the curvature using a rotational matrix to move the distal point to the target puncture location while holding the proximal point fixed.
