I tried to look it up, and apparently there is something called “black heart”
Apparently it’s something to do with how the potato has been stored. Something about a lack of oxygen, but I don’t know anything other than the few searches I found.
There probably are other and better sites out there about this topic, but I think it is possible it could be black heart even though the pattern in yours looks unusual, but honestly, what do I know? XD
