Percutaneous left atrial appendage occlusion: the Munich consensus document on definitions, endpoints and data...

Area of Science:

• Cardiology
• Medical Devices
• Stroke Prevention

Background:

• Growing interest in Left Atrial Appendage Occlusion (LAAO) for preventing ischemic stroke in atrial fibrillation (AF) patients necessitates robust clinical data.
• Existing data gaps require further assessment of LAAO safety and effectiveness, particularly in specific patient subgroups.
• Comparisons with traditional pharmacological prophylaxis, surgical interventions, and alternative device-based therapies are crucial for comprehensive evaluation.

Purpose of the Study:

• To establish consensus on definitions for parameters and endpoints in clinical studies evaluating LAAO.
• To promote a standardized approach for assessing LAAO across diverse clinical studies and stakeholders.
• To facilitate the ongoing evaluation of LAAO as a therapeutic strategy for stroke prevention in AF.

Main Methods:

• Convened clinical experts from Europe and North America across relevant disciplines.
• Included European cardiology professional societies and medical device industry representatives.
• Documented consensus on definitions for parameters and endpoints for LAAO clinical trials.

Main Results:

• Achieved consensus among multidisciplinary experts and stakeholders on key definitions for LAAO studies.
• Proposed standardized definitions to ensure consistency in data collection and reporting.
• Facilitated a unified approach for evaluating LAAO efficacy and safety.

Conclusions:

• Standardized definitions are essential for consistent and comparable clinical studies on LAAO.
• Adherence to consensus definitions will improve the evaluation of LAAO safety and effectiveness.
• This initiative supports the continued development and optimization of LAAO therapies for stroke prevention in AF.
