Left atrial appendage closure: the journey today and tomorrow.

PURPOSE OF REVIEW: This review aims to discuss the rationale behind the development of percutaneous LAAC devices as a treatment option for atrial fibrillation patients ineligible for long-term anticoagulation. The evolution of LAAC, from early experiences and challenges to risk mitigation and improved devices and techniques, will be examined. Furthermore, the review will explore our current understanding of the potential and limitations of LAAC in stroke prevention.

RECENT FINDINGS: Multiple trials confirm LAAC device safety and efficacy for stroke prevention, but peri-device leak and thrombus remain concerns postimplantation. Even small leaks pose increased stroke risk. While guidelines suggest short-term anticoagulation postimplant; real-world data show equivalent efficacy with dual antiplatelet regimen.

SUMMARY: LAAC device design has evolved and now serve as a viable option for stroke prevention in high-risk atrial fibrillation patients, offering protection in the absence of anticoagulation.
