Can I ask you to clarify your question a bit? By "not survive the Atlantic passage", do you mean "weren't brought across via ship"? Or do you mean "they aren't much of a traditional dish here"?

If the latter case, it's because we aren't exclusively English. There were several cultures brought together in the Americas, and while some dishes from back home would have been made for a time, as those people intermingled and worked together, they would have developed their own dishes, in the same way they developed their own culture. In Canada, for example, along with the First Nations people, there were English, Scottish, Irish, French, German, Dutch, Ukrainian, and a litany of other settlers who populated the land. While in some cases, a few traditional foods survived (many more Manitobans than PEIers enjoy perogies), often they combined aspects of various cultures (Acadian rappie pie has some French roots, along with some German and Swiss, and possibly a few others; the exact history isn't known).

I'd like to rephrase it more generally : why and since when have Americans been using a much more restrictive definition of "food" than Europeans ? Why don't they eat, at least not commonly, liver, brains, hearts, blood, intestines etc., even though it's common to eat such things throughout Europe ?
