the one thing I hate about cardiology is the ever expanding scope of practice regarding imaging/procedures. Pretty soon a general cardiologist will just be someone who runs consults, does echoes+TEEs/stress echo but leaves CTs, nukes, MRIs, structural TEEs, diagnostics, rights, etc etc to more specialized cardiologists.
This will probably be the future. There will likely be an advanced imaging board certification as well.
The one thing that abundantly fights this sub-specialization within imaging is the lack of payment and low wRVU (you need to be salaried and supported). Even Chest radiologists hate cardiacs because it's so underpaid for the time needed for interpretation compared to cranking out CT PE's and CXR's.
That being said, CT's
will be the future of Cardiology. It will take over stress testing. It will be the basis for un/complicated structural planning.
Here's some simple math for the above mentioned.
TTE ~1.5wRVU (15 minute read)
TEE ~2.6 wRVU (30 minute perform)
32 TTE's/day 48 wRVU's (honestly you should be able to read more than that in a day, too)
------------
MIBI ~2.4 wRVU (15 minute read)
Structural TEE ~4.5 wRVU (60-120 minutes; criminal compared to the ~32 the IC gets for a clip!)
Cardiac MRI ~2.6 wRVU (45 minutes reconstruction + read, doesn't account hand holding the technologist)
Cardiac CT ~2.4 wRVU (45 minutes reconstruction + read, doesn't account hand holding the technologist)
8 advanced studies/day ~21 wRVU's
4 structural cases/day ~18 wRVU's
