It is unlikely that A* ever read εν τη καρδια: The current εν is written over a correction (not the -ν- but that one is made up out of pre-existing verticals) which would not need to be changed if A* had εν already, the current αι of ταις seem to belong to the pre-existing text, but all other letters on this line are written over an erasure, but the current -διαις on the next line is original and untouched, suggesting the correction on the previous line was made before the next was written (or if not, that the word already ended on -διαις in the version of A*).

A possible improvement is to cite A* as having [...]διαις
