Summary
Transcatheter left atrial appendage closure (LAAC) is increasingly used to prevent stroke in atrial fibrillation patients. This updated consensus provides evidence-based recommendations for contemporary endovascular device practices.
Area of Science:
- Cardiovascular medicine
- Interventional cardiology
Background:
- Surgical left atrial appendage exclusion dates to 1949.
- Transcatheter endovascular left atrial appendage closure (LAAC) has rapidly advanced over two decades.
- LAAC procedures have surged globally since 2015.
Framework:
- Previous Society for Cardiovascular Angiography & Interventions (SCAI) statements were issued in 2015 and 2016.
- Updated recommendations are based on recent clinical trials, registries, and technological advancements.
- Focus on contemporary, evidence-based best practices for endovascular LAAC devices.
Implementation:
- Requires institutional and operator expertise.
- Evolving device and imaging technologies are crucial for successful LAAC.
- Standardized protocols ensure patient safety and procedural efficacy.
Implications:
- Improved thromboembolic risk reduction in atrial fibrillation.
- Enhanced patient outcomes through minimally invasive procedures.
- Guidance for healthcare providers on optimal LAAC strategies.
