Shortening fraction is similar to ejection fraction which both measure left ventricular performance. Single PVC's and PAC's are really nothing to worry about unless the frequency of these premature beats dramatically increases. Only your daughter's cardiologist can decide whether a heart catheterization is indicated - I am unable to make such a recommendation in this forum. I understand that you don't want your daughter to suffer, but a heart cath may indeed help with her management, so make sure you voice your concerns if she ends up needing a heart cath. I hope you find this information useful.
