Area of Science:

  • Cardiovascular Interventions
  • Medical Device Technology
  • Interventional Cardiology

Background:

  • Prior surgical left atrial appendage (LAA) ligation can be incomplete, posing risks.
  • Failed attempts at LAA closure require alternative strategies.
  • Complex LAA anatomy presents challenges for device implantation.

Purpose of the Study:

  • To describe the percutaneous closure of a previously ligated LAA.
  • To report the use of a new-generation Watchman FLX device in a challenging case.
  • To highlight the role of multimodality fusion imaging in complex LAA interventions.

Main Methods:

  • Percutaneous implantation of a Watchman FLX device.
  • Utilized multimodality fusion imaging for procedural guidance.
  • Managed a patient with prior incomplete LAA surgical ligation and failed device closure.

Main Results:

  • Successful implantation of the Watchman FLX device.
  • Achieved closure in a technically and anatomically challenging LAA.
  • Demonstrated feasibility of advanced imaging in complex LAA interventions.

Conclusions:

  • Percutaneous closure with the Watchman FLX device is a viable option for complex LAA cases.
  • Multimodality fusion imaging is crucial for challenging LAA interventions.
  • This approach offers an alternative for patients with prior failed LAA closure strategies.
