That is utter BS. As in IR fellow we do mesenteric angiography ALL the time. Unless you actually select (seek and catheterize) the renal arteries, you CAN'T actually tell whether or not there is stenosis in a renal artery. We do Aortic angiography when we absolutely cant find the orifice of a mesenteric vessel (the renals are in the same neighborhood) and even then you dont get a true sense of whether or not stenosis of the renal artery.
A cardiologist who is trying to catheterize the coronaries "due north" of the renals, would have even less of a chance of seeing the renals well enough to make a call of stenosis.
The other thing is you use the minimal amount of contrast to get the job done... Contrast can be nephrotoxic. The additionally, there is a risk of dissecting a vessel when you catheterize it. You don't select vessels just for the hell of it unless there is an indication to do so.
The IC decides to go to the renal vessels? Based on what indication? As an IR I work right next to the renals all the time, I could easily do a renal angiogram, but I don't... Why? Because there is no indication to do so. Its not the right thing to do.
If you look at the reimbursement for procedures, coronaries are 800-1000 bucks. Renal angioplasty and stenting, because its new, is close to 6000 bucks. Does something smell fishy to you?
i'm not an interventional cardiologist, and have no stake (personally or professionally). but when i get a patient after heart cath who's received a stent to the circumflex, and another in a renal artery... clearly the cardiologist decided to make his way to the level.
and that was my point.
there are physicians out there who will do the right things for the right indications.

in my opinion, a cardiologist looking at the renal artery on a stemi patient is doing the wrong thing.
but you might be surprised what you see if you ventured over to a cardiac cath. as i have seen more than one cardiologist (in separate groups), go ahead and shoot the renal arteries.
i'm not saying its right or wrong (i happen to think its wrong fyi), but it does indeed happen.
so, if an ir guy/gal knows this is going on in his/her hospital... i would think that it could contribute to a turf war, as it would affect the politics in the hospital... not to mention, people checking up on privileges, equipment, etc. ... a slippery slope indeed.
