Background:To quantiy the incremental cost associated with right ventricular ailure (RVF) ater let ventricular assist device (LVAD) placement.

Methods: Data on HeartMate XVE (n=107) and HeartMate II (n=58) LVAD recipients rom 1/1/03-1/1/09 at our institution were retrospectively

reviewed. Total hospital costs were adjusted to post-op costs using multivariable regression and stratifed by billing category (Table 1). Clinical

outcomes included: development o post-op RVF, need or RVAD, ICU length o stay (LOS), and in-hospital mortality.

Results: Among all LVAD recipients, 28.5% (n=47) were diagnosed with post-op RVF, and o these 42.6% (n=20) required an RVAD. RVF was

associated with a mean $89,955 34,279 higher post-op cost o hospitalization (p=0.01). The increased cost o RVF was driven by an increase in

mean direct ($71,375 21,012; p=0.001) versus indirect ($23,007 21,413; p=0.284) costs. RVF requiring insertion o an RVAD was associated

with a $273,619 34,359 higher post-op cost o hospitalization (p
