Interventional Cardiology

Left Atrial Appendage Closure

WATCHMAN FLX™ Pro is the leading LAAC therapy for stroke prevention.

Over 80% of people with AFib on blood thinners are open to trying a new treatment to lower their stroke risk.2  

The WATCHMAN™ device effectively reduces the risk of stroke—without the risk of bleeding that can come with the long-term use of blood thinners.3,4 This makes left atrial appendage closure (LAAC) therapy an important option for patients with a history or risk of serious bleeding on blood thinners.

Designed to improve implant success, the WATCHMAN TruSteer Access System optimizes coaxial device positioning in the widest range of left atrial appendage (LAA) anatomies. 

WATCHMAN FLX Pro device showing the size range up to 40mm

The WATCHMAN FLX Pro Device is designed with three first-ever features:  

  • New 40 mm size for larger appendages. 
  • New HEMOCOAT Technology designed to improve the healing process.5 
  • Radiopaque markers for precise device placement. 

With a 25% increase in device size range, the WATCHMAN FLX Pro unlocks up to 6% growth in the treatable patient population. 

Clinical outcomes

OPTION Clinical Trail

Boston Scientific announced positive results from the OPTION Clinical Trial at the AHA Scientific Sessions 2024 on November 16. OPTION is the first randomized, head-to-head study comparing WATCHMAN FLX™ Left Atrial Appendage Closure Device to oral anticoagulants (OACs) (95% dual oral anticoagulants (DOACs) post atrial fibrillation ablation.6

OPTION Three-Year Primary Endpoint Results:  

  • Superior safety profile of non-procedural major bleeding at 36 months compared to OACs. 
  • Equivalent efficacy to OACs at preventing all-cause death, stroke, or systemic embolism at 36 months.  

This allowed patients to eliminate continuous medication use, significantly reducing bleeding risk while maintaining stroke protection. 


Patient experience

Boston Scientific is dedicated to supporting patients at every step of their journey to WATCHMAN. Our patient campaign identifies, activates, and educates eligible patients about the WATCHMAN Implant as an alternative to blood thinners for managing stroke risk and bleeding worry. 

Digital tools and templates are available to help you educate patients and increase local awareness for your WATCHMAN program. Download WATCHMAN Patient Materials and Hospital Media Kit.

HAWKEYE notifies your team of any pre-procedure or post-implant tasks to support program compliance and the best possible patient experience. HAWKEYE helps you understand program performance and patient outcomes, making it easier to optimize operational efficiencies and streamline patient coordination. 

LAAC program economics

LAAC for stroke protection with WATCHMAN FLX Pro Left Atrial Appendage Closure Device is one of the fastest growing procedures in cardiology. 

Health economics and market access support

On October 1, 2024, CMS released the final inpatient prospective payment system (IPPS) rule for FY 2025 which approved a new MS-DRG 317 for concomitant intracardiac ablation and left atrial appendage closure procedures. This rule is effective for hospital discharges on or after October 1, 2024. 

WATCHMAN reimbursement

A dedicated team of health economics professionals can help you understand the economics of your LAAC program at various levels through: 

Program economic overview
Our team uses public data to identify current-year reimbursement, historic cost details like LOS, and DRG mix, comparing hospital-specific benchmarks with national, state, and CBSA levels. 

Program economic deep-dive
Using customer-specific ICD-10-CM/PCS data, our team analyzes coding, charges, and direct costs of the LAAC program to identify opportunities to improve revenue cycle management, calculate contribution margin, and compare hospital specific performance year-over-year.
