Background: Early studies demonstrated feasibility of minimalist conscious sedation (CS) for Transfemoral (TF) access for transcatheter aortic valve replacement (TAVR). A recent STS-ACC TVT Registry analysis demonstrated that a CS TF-TAVR has lower mortality, stroke, and shorter length of stay (LOS) vs. general anesthesia (GA) TF TAVR.

We recently reported that a novel anesthetic approach using a fasica iliaca compartment block (FICB) + CS for patients undergoing TF TAVR was associated with a shorter operating room time, shorter imaging time, lower incidence of blood transfusion, and shorter LOS as compare to GA. Whether these results can be used to further demonstrate a reduced cost of FICB + CS as compare to GA in patients undergoing TF TAVR is currently not known.

Methods: Completed billing information in 65 consecutive patients who underwent balloon expandable TF-TAVR using GA or FICB + CS between the billing cycle of January 2013 and December 2015 were collected.


Conclusions: The result of this study suggest that FICB + CS may be associated with lower cost than GA, due in part to lower cardiology cost, shorter time in the operating room, and shorter ICU LOS in patients undergoing balloon expandable TF TAVR.
