NCT06436924

Brief Summary

SAFE HV is an observational, prospective, multi-center, non-randomized study evaluating real-world clinical experience of centers where a single procedural physician schedules eight or more left atrial appendage occlusion (LAAO) device implant procedures in a single calendar day.

Outcome Measures

Primary Outcomes (3)

  • Peri-procedural complications

    Incidence of peri-procedural complications summarized descriptively and compared to historical data

    Procedure through discharge, an average of 1-3 days

  • Peri-device leakage

    Assessed by successful closure of the left atrial appendage defined by peri-device leakage of \<5mm. This will be identified at the post implant imaging.

    Date of implant up to 90 days

  • Late onset complications

    Incidence of post procedure complications summarized descriptively and compared to historical data.

    Discharge to 30 days.

Study Arms (1)

Subjects undergoing LAAO device implant

Watchman LAAO device implant

Device: Left Atrial Appendage Device Implant

Interventions

The Watchman Device is implanted into the left atrial appendage and is designed to close it off and keep blood clots from escaping that area.

Subjects undergoing LAAO device implant

Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodProbability Sample
Study Population

The study population will include subjects who are clinically qualified for a Watchman FLX™ or Watchman FLX Pro™ LAAO device implant and would receive one regardless of participation in the study, who meet all eligibility criteria for the study, and present at participating institutions for a LAAO device implant procedure on a day in which a single implanting physician scheduled at least eight LAAO device implant procedures, regardless of the device manufacturer (i.e., high-volume).

You may qualify if:

  • years of age or older
  • Able and willing to participate in baseline and follow up evaluations for the full length of the study
  • Clinically qualified, in the opinion of the Investigator, to receive a LAAO device
  • Receiving a Watchman FLX™ or Watchman FLX Pro™ LAAO device as part of their plan of care
  • Having their LAAO device implant procedure scheduled on a qualifying high-volume\* procedure day as assessed within 2 days (≤ 2 calendar days) prior to the planned procedure date
  • \*high-volume - a calendar day in which the single implanting physician schedules ≥ 8 LAAO device implant procedures, regardless of the device manufacturer
  • Willing and able to provide informed consent

You may not qualify if:

  • Enrolled in an investigational drug or device clinical trial, or any trial that dictates the treatment plan
  • In the opinion of the Investigator, any known contraindication to a LAAO device or implant procedure
  • Having their LAAO device implant procedure scheduled on a day in which the single implanting physician scheduled \< 8 LAAO device implant procedures as assessed within 2 days (≤ 2 calendar days) prior to the planned procedure date
