Cardis are pretty healthy. The most common issue is PRA (eyes) but there's a DNA test and even carriers are pretty rare in the US. Obesity and obesity-related back issues can be a problem as dogs age, but it's not a genetic one- it's a feeding-and-cuteness issue.

Dogs kept at a proper weight (and they have very efficient metabolisms, so they eat less than you'd sometimes suspect) are not too prone to back issues, although injuries can obviously still happen. Other problems include an intolerence or allergy for corn (not a huge issue but reasonably common, I know of a few Cardis with it), heart problems (very rare, but I've heard of a few more recently), and hip dysplasia, although again, not a huge issue.
I honestly feel that temperament is a bigger issue with Corgis than health- if the dog iss not a resource guarder, is not dog aggressive, and has been properly socialized, those are all BIG bonuses. Cardis can be somewhat reactive, particularly if they'er not socialized enough, and they're not as outgoing overall as Pems. They can be obnoxiously dog aggressive, too, and tehy're stubborn- setting (and enforcing!) limits is important with this breed, as is giving them clear expectations as to what you expect them to do.
