Heterocyclic declination
Heterocyclic declination was a condition, the prevention of which was a necessary precondition to the successful outcome of a cardiac implant.

According to the Starbase 515 surgeon, the inability to reverse  – and the lack of metabilation occlusion – were primarily responsible for the initial failure of Captain Jean-Luc Picard's secondary implant surgery. These failures forced the doctor to seek additional help from a biomolecular physiologist, who was able to recommend that Katherine Pulaski correct the issues. ()
