摘　　要：Objective: Anticoagulants have been approved and used for decades as highly effective blood thinners. The objective of this study is to analyze the clinical trials in order to determine if the Watchman reduces the risk of stroke in patients with atrial fibrillation compared to those prescribed the traditional anticoagulants. This will contribute to the current body of knowledge and possibly provide beneficial clinical guidance with respect to providing an alternative option for those suffering from non-valvular Atrial fibrillation. Methods: A systematic literature search through the Saint James School of Medicine library resources as well as PubMed, Medscape, Google Scholar was conducted. Studies were included if the literature examined the comparison between the Watchman device and four specific anticoagulants (Xarelto, Eliquis, Pradaxa, and Warfarin) in association with reduction of risks of strokes in an atrial fibrillation population. The study includes a qualitative sub-analysis to explore additional clinical aspects that may affect risk of stroke and response of treatment. Results: Outcomes were significant for similar stroke occurrence, when compared to published clinical trials. Alternatively, there was a significant reduction in risk of bleeding and all-cause mortality in the Watchman™ device compared to traditional NOACs and warfarin. While examining the studies and trials, overall, the Watchman™ device offers a better long-term outcome therapy for non-valvular atrial fibrillation populations who are not possibilities for extended anticoagulation. The studies used for analysis examining the dosage found higher fatality with increased use of NOACs and more hospitalizations with decreased use. Conclusion: From the presented data, it is safe to say that the Watchman™ device is a viable and effective alternative for stroke prophylaxis in certain patient populations. Compared to traditional anticoagulant therapies for non-valvular atrial fibrillation, these studies suggest that the Watchman™ device cObjective: Anticoagulants have been approved and used for decades as highly effective blood thinners.
