Conclusion:
In conclusion, in this large, nationally representative sample of a
United States database, there has been a significant increase in the use
of Watchman devices since FDA approval in 2015. Between 2015 and 2017, a
significantly reduced rate of procedural complications and in-hospital
mortality was noted, which appeared primarily driven by reduction in
cardiovascular and neurological complications. In later years, length of
stay shortened and costs of hospitalization for the procedure decreased.
