Complete nonsense.

If it worked everybody would not just want to do it, they'd have to do it. It doesn't, so they don't.

I don't think that's entirely fair. As has been mentioned, it's only one factor out of many that make up a successful racehorse - length of stride, soundness, courage, size. Plenty of horses succeed without one of the aforementioned factors in their favour. The question is whether it's advantageous, and there's plenty of evidence that it is.

When it's discovered upon his death that possibly the greatest racehorse of all time (Secretariat) had a heart almost 3 times larger than the average thoroughbred then questions should and have been asked. From what I can see nothing has been proved nor disproved, but if I was lucky enough to be able to afford to race or breed these fantastic animals then I'd be all over this theory like a rash. It gives the opportunity to acquire a nice animal(s) at a price that may be unthinkable in a few years time if the link is proven.

A recent article I found on this is shown below:

I read the article. It's interesting to me that the author used Eavesdropper as his example of a horse with the "coveted" Large Heart Gene. Eavesdropper was only moderately successful as a racehorse and he was a failure as a sire in the U.S. (35% winners, 0% stakes winners.) So what was his LHG supposed to have helped him with?

TBird, I only included that link because it was recent (written a month ago). For me a more interesting article is shown below;

I just chanced upon this topic whilst browsing the web and found it interesting. Is it positively talked about in breeding circles, treated as mumbo jumbo or not discussed at all?

If I have read correctly, the Large Heart Gene possessed by Secretariat is passed through the daughters, which may be one reason Big Red ended up being a really good broodmare sire. So, perhaps it would be worth following Eavesdropper's daughters to see if he also has success there?

There are plenty of people scanning hearts, and they have no more success than anyone else. In fact, I can't think of any really top buyers who do it, but they still get out a higher % of stakes winners than the heart score nuts.
