I think it's tough to answer this. I would generally say that you will get adequate training at most places. You have to keep in mind that a lot of the bad programs out there shut down when cardiac surgery went through a lull, and the ones that stuck around were the ones that were generally solid. The ones that re-opened, or recently started have programs where at least the potential is there. There are a handful of places that people will often advise you avoid. But like general surgery, there is going to be a broad definition of what people consider "good training". It depends a lot on the resident and what he or she is trying to get out of the program.
Whilst I understand the idea behind asking this (and having interviews online IS going to change the dynamic), however, in the end, I think the dog and pony show that is presented on interview day, even when its in-person, is of somewhat limited value. The same rules apply, you need to talk to fellows and recent graduates, because the personalities and focus of each program can differ.
