CV Anesthesiology and CT surgery both cannulate.
CV Anesthesia for VV, ARDS lung rescue with a call pool, VA, VAV for eCPR in-hospital arrest
CT surgery for ED ECMO (rare), OR cases (Obviously), If CT surgery is not operating then they will be around for hands on help for VV, etc.
Perfusion runs machines.
Pre-lung transplant and intraop lines for transplant are still being worked out with CT surgery and CV Anesthesia. The general tone is CT surgeons are more friendly in the sandbox with CV Anesthesia then Cardiology. All Devices (LVADs, ECMO, Centrimag, RVAD, IABP) go to CT ICU that is pure Anesthesia and CT surgery. Obviously MIs with impella, IABP stay in CCU.
TEE for all cannulation. Usually there is an IMACOR hTEE left for 48 hours. Rarely the patient will need flouro, which if needed can be done at bedside with a C ARM in the unit.
Most decannulation is in the ICU without "anesthesia" - but not sure what that refers to since the CT ICU is anesthesia staff and likely they had input and decision making into the timing of decannulation.
If OR decannulation then anesthesia is doing "anesthesia."
The overall theme is devices, ICU care, and cannulation is time and labor intensive. It can be financially beneficial for a CV group and usually the CV surgeons are comfortable with Anesthesia staff. Start with TEE, then ICU care, and then cannulation and rescue.
