Background: Transcatheter Aortic Valve Replacement (TAVR) has become the standard of care for inoperable or high-risk patients with symptomatic severe aortic stenosis. We sought to compare clinical characteristics and in hospital procedural outcomes in patients receiving periprocedural blood transfusions.
Methods: ICD-9-CM procedure codes were used in HCUP-NIS database to identify all patients undergoing TAVR between 2011-2013 with and without periprocedural blood transfusion. In-hospital all-cause mortality, total costs related to hospitalization, mean length of stay (LOS) and procedure-related complications were assessed. Propensity score matching was used to adjust for multiple confounders.
Results: Transfused patients were more likely to be female, older, with hypertension and chronic renal failure. Transfusions were more common in patients undergoing transapical TAVR or those requiring intra aortic balloon pump. They were associated with increased in-hospital mortality, periprocedural complications, LOS and hospital expenses and similar rates of permanent pacemaker requirement. After propensity score-based adjustment, LOS, hospital related expenses and incidences of in-hospital mortality, acute stroke and acute renal failure were significantly higher in the transfused cohort (Table 1).
Conclusions: In patients undergoing TAVR, periprocedural blood transfusions are associated with increased in-hospital mortality, LOS and hospital expenses.
