CTS- fellowship is no desirable for several reasons:
1) long training period. 5-7+ yrs of G-surg then 2-3 yrs of CTS
(if you want ped-ct, you may have to put in 1 extra yr, and no, you may not do a ped-surg fellowship instead of the CT fellowship. This simple reason is the CT-surg board will not board you for cardiac surgery.)
2) Bad life style, the dissecting aorta and the stent complications never happens during daytime (I think this is just Murphy's Law). They happen on the last stent case of the day , or finally gets diagnosed by the ER at 10pm. So, you start the case at midnight if lucky, and you'll be home no earlier than 4-6 am. Remember, your first case is usually 7:30 am. That is why many don't even go home til the next evening.
3) The number of cases (mainly CABG) is decreasing. This is simply the effect of the non-re-occulsive stents. The number out of Harvard published in the NY times several months ago suggest a possible drop of 25% (this number was given to the NY times by the Cardiothoracic surgery department).
Cardiologist are still not making the same salary as CT-surg in an academic institution.Cardiothoracic surgeons can do what the cardiologist are doing with the stent techonolgy, but they gave up that turf many years ago. It will be a cold day in hell when the cardiologist will share that gold mine with the surgeons.
The referral bit for money sound like a urban legend to me. It is totally illegal either way he was putting it. If any practice are doing that, the surgeons involved should reported the cardiologist/ group to their state medical board, and the FTC for unfair business practice.
But, Urban legends are the reason why I come to get a good laugh.
