SURPASS
1 Year Results

The SURPASS 1 Year Outcomes analysis of the NCDR-LAAO Registry™ now includes the largest number of commercial WATCHMAN FLX™ Device patients to date. These data continue to support the best-in-class safety of the WATCHMAN FLX Device with a 0.45% major procedural adverse event rate within 7 days or hospital discharge (whichever is later) and 98% implant success in >97,000 real-world NVAF patients.1

Study design

  • The objective of this SURPASS analysis is to assess long term safety and efficacy outcomes at one year with WATCHMAN FLX in a routine, real-world setting.​
  • This analysis includes the largest commercial WATCHMAN FLX patient population to date, with 97,185 patients implanted between August 2020 and September 2022. ​

Patient characteristics:

  • Age: 76.4 ±7.9 Years​
  • CHA2DS2-VASc Score: 4.8±1.5
  • ​HAS-BLED Score: 2.8±1.0​
  • Women: 41%​
  • Clinically Relevant Bleeding: 56.1%
Safety Endpoint

The 0.45% major procedural adverse event rate within 7 days or hospital discharge demonstrated in the SURPASS 1 Year Outcomes analysis further supports the unmatched safety profile observed in separate controlled and real-world analyses.​
