Atrial fibrillation (AF), the most typical sustained cardiac arrhythmia, is growing in incidence and prevalence worldwide. AF considerably will increase the chance of intracardiac thrombus formation and, if left untreated, ischemic stroke. In sufferers with nonvalvular AF (NVAF), the left atrial appendage (LAA) has been decided to be the supply of thrombus growth in 91% to 99% of instances. On this regard, oral anticoagulants (OACs) have turn into the usual therapy for stroke prevention in most sufferers with AF; nonetheless, OACs are related to a threat of bleeding problems, and their efficacy is determined by optimum affected person compliance. Amongst various approaches to embolic stroke prevention, surgical LAA excision for stroke prevention for valvular AF was tried as early because the late Nineteen Forties. LAA excision stays really useful in surgical pointers for sufferers with NVAF requiring open-heart coronary bypass or valvular substitute/restore surgical procedures. Nevertheless, owing to the traumatic/invasive nature and suboptimal outcomes of standard surgical LAA intervention, medical software of this strategy is restricted in present cardiology observe. Percutaneous LAA occlusion (LAAO) is more and more being carried out as an alternative choice to OAC for stroke prevention, significantly in sufferers with elevated bleeding threat.
Substantial progress has been made in percutaneous LAAO remedy since its inception roughly 20 years in the past. This text systematically opinions the literature resulting in the event of LAAO and the evidence-based medical expertise supporting the appliance of this therapy technique for NVAF, with a deal with just lately revealed vital evaluations of US FDA and CE mark accredited LAAO units. Future views concerning data and expertise gaps are additionally mentioned, recognizing the various ongoing medical trials which can be more likely to be transformative and the vital unanswered questions concerning LAAO remedy.
