The truth is this question has no clear answer and what with do with peripheral stenting is transfer the evidence we have on coronary stenting, given the lack of standards and poor reporting on antithrombotic therapy outcomes in randomized studies on endovascular intervention. Heterogeneity is worse when it comes to venous territory. Some time ago…
Virtual ACC 2020 | PRONOMOS: Rivaroxaban Superior to Enoxaparin in Orthopedic Surgery
According to this new study presented virtually at the suspended American College of Cardiology (ACC) 2020 Scientific Session and published simultaneously in the New England Journal of Medicine (NEJM), rivaroxaban is more effective than enoxaparin in preventing venous thromboembolism during a period of immobilization after nonmajor orthopedic surgery of a lower limb. After an orthopedic…
Virtual ACC 2020 | POPULAR TAVR: Post TAVR Anticoagulation without Clopidogrel?
In patients undergoing transcatheter aortic valve replacement (TAVR) that also required anticoagulation for another indication (mostly atrial fibrillation), the incidence of major bleeding between month 1 and 12 was lower in those receiving only anticoagulation instead of anticoagulation + clopidogrel. The present study presented as part of the scientific sessions at the virtual ACC 2020,…
Virtual ACC 2020 | Antidote for Life-Threatening Bleeding with New Anticoagulant Agents
Among patients hospitalized with life-threatening or uncontrolled bleeding under treatment with direct factor Xa inhibition, anticoagulation reversal with andexanet alfa (Andexxa) was associated with low mortality rates. These promising results have multiple limitations, particularly the lack of definition on bleeding severity. One of the studies testing the new antidote used propensity-score matching, and there were lower…
Virtual ACC 2020 | VOYAGER PAD: Rivaroxaban Superior to Aspirin in Preventing Events
In patients with peripheral artery disease undergoing revascularization, the combination of rivaroxaban (Xarelto) and low doses of aspirin are superior to aspirin alone in the prevention of acute low limb ischemic events, amputation, cardiovascular events and strokes. The outcomes of VOYAGER PAD add to the COMPASS outcomes, showing the combination of therapies can benefit risk…
Virtual ACC 2020 | COMPASS Sub-Analysis: Diabetes Increases the Benefit of Rivaroxaban Combined with AAS
In patients with stable coronary or peripheral artery disease, diabetes increases the benefit of combining low doses of rivaroxaban and aspirin vs. aspirin alone. This analysis was pre-specified in the COMPASS protocol and was presented virtually for the ACC 2020 and simultaneously published in Circulation. Patients with diabetes, showed numerically greater reduction in terms of…
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…
AHA 2019 | GALILEO: Rivaroxaban After TAVI, Another Nice Theory that Clashes with Reality
In patients without formal indication for oral anticoagulation after successful transcatheter aortic valve implantation (TAVI), a treatment strategy including rivaroxaban 10 mg daily was associated with a higher risk of death or thromboembolic complications and, on top of that, a higher risk of bleeding than a conventional antiplatelet strategy. So far, we did not know whether…
AHA 2019 | GALILEO-4D: Rivaroxaban in the Prevention of Post TAVR Valve Thickening and Thrombosis
This sub study of the GALILEO specifically looked at valve thickening and reduced leaflet motion after TAVR documented with 4D CT. Whether anticoagulation with rivaroxaban might reduce or prevent this phenomenon remained unanswered. Patients receiving the same anticoagulation scheme than the general study’s (rivaroxaban + aspirin vs. aspirin + clopidogrel) were assessed by 4D CT…
