Background: Intra-Aortic Balloon Pump (IABP) placement is common in patients (pts) undergoing Transcatheter aortic valve replacement (TAVR) to preempt or treat peri-procedural hemodynamic instability. We sought to evaluate clinical outcomes in pts with and without IABP placement during hospitalization for TAVR procedures.
Methods: Study subjects were obtained from the 2011-2013 HCUP-NIS database. ICD-9-CM procedure codes were used to identify all TAVR and IABP cases during the same hospitalization. In-hospital all-cause mortality, total costs related to hospitalization, mean length of stay (LOS) and complications rates were assessed. Propensity score matching was used to adjust for baseline and procedural confounders.
Results: Of the 222,245 TAVRs performed during the study period, IABP was utilized in 503 (2.3%) procedures. TAVR pts who required IABP were younger, male, with a higher incidence of chronic renal disease, pulmonary hypertension, congestive heart failure and active tobacco use. After propensity score-matched adjustment, pts with IABP had higher in-hospital all-cause mortality, peri-procedural stroke, blood transfusion and acute kidney injury, longer LOS and higher total hospitalization costs. (Table 1)
Conclusions: IABP placement in patients undergoing TAVR is associated with a higher incidence of in-hospital all-cause mortality, peri-procedural stroke, blood transfusions, acute kidney injury along with a longer LOS and higher hospitalization-related costs.
