You're basing your opinion on residents that you've seen who are happy with the program, and have gone to national meetings combined with the outward appearance of the directors at their organization's annual meetings.
I interviewed with both Dr. Angle and Sabri, and spoke at length with Dr. Matsumoto. I agree that they all are very nice, answered all questions I had, and were extremely excited about their program. They are willing to work hard and get good results with their trainees. However, I feel there is a huge selection bias. If you put those trainees who go to the UVA VIR program at nearly any other program in the country, they're still going to end up being great IR residents (and also love their program) because they're highly motivated and enjoy what they do.
For the most part, I agree that it's good training. I just think they're going very overboard with this whole "clinical representation" thing. If they want IR clinics and IR specific rotations, awesome, but scutting Rads residents out to Cardiology and Vascular Surgery is nonsense. Yes, those reports are few, but they do happen.
I could see myself doing fellowship there, but the residency was pretty off-putting to me, for the reasons I've mentioned already. I know I probably sound like I'm badmouthing them, but I'm really not. I would never actively try to convince someone to not go there, just stating my opinion.
