Atrial fibrillation is the most prevalent arrhythmia and to prevent its potential complications, we should administer anticoagulants (OACs), either warfarin or the new direct oral anticoagulants (DOACs). Even though these drugs have been shown effective, they still involve the risk of bleeding, especially gastrointestinal bleeding, which in turn leads to numerous hospitalizations. Left atrial appendage occlusion…
Atrial Fibrillation and Dementia: Which Anticoagulant Agent Presents the Lowest Risk?
Atrial fibrillation is a risk factor for dementia and anticoagulant agents have been proven to decrease it. This work aims to find differences in the risk of dementia between patients treated with traditional choice warfarin vs. different direct anticoagulants. Between 2014 and 2017, this study enrolled 72,846 patients >40 years with nonvalvular atrial fibrillation who…
AAS vs Warfarin in Low Risk TAVR
We are still discussing the adequate antithrombotic scheme after transcatheter aortic valve replacement (TAVR). Additionally, we are treating a much wider array of patients ranging from low risk to inoperable. And there is yet one more important point: hypo-attenuated leaflet thickening diagnosed by CT. We are still unaware of the impact they have on device…
AHA 2020 | RIVER: Rivaroxaban as Alternative to Warfarin in Patients with Atrial Fibrillation and Bioprosthetic Mitral Valve
Rivaroxaban seems to be a reasonable alternative to warfarin in patients with atrial fibrillation and bioprosthetic mitral valve. These results arise from the RIVER Study presented at the American Heart Association (AHA) 2020 Congress and simultaneously published in the New England Journal of Medicine (NEJM). After 5 years of follow-up, rivaroxaban reached the non-inferiority criterion…
Benefit of Anticoagulation in the Elderly with Atrial Fibrillation
Guidelines recommend oral anticoagulation for all ≥ 75-year-old patients with atrial fibrillation. However, there is little evidence as to its net clinical benefit in the elderly population. This study looked at the life net clinical benefit in atrial fibrillation patients over 75 years of age treated with warfarin or apixaban vs. no treatment. Researchers observed…
Net Benefit of Left Atrial Appendage Closure vs. Anticoagulation in Atrial Fibrillation
This analysis shows that the long-term clinical benefit of left atrial appendage closure with Watchman is superior to warfarin in patients with atrial fibrillation (AF). The initial peri-procedural risks of device implantation are counterbalanced over time, with reduced risk of bleeding and death. The PROTECT-AF (Watchman Left Atrial Appendage Closure Technology for Embolic Protection in…
