The Impact of Community Use of Novel Oral Anticoagulants on an Academic Medical Center

Warfarin has been a mainstay of therapy for treatment and prevention of venous thromboembolic disease (VTED) and prevention of stroke and systemic embolism for over 50 years. Recent FDA approval of several novel oral anticoagulants has offered more extensive treatment options for management of these disease states. The availability of the novel anticoagulants offers an attractive alternative to warfarin therapy for patients due to their convenience of use. In comparison to warfarin, dabigatran, rivaroxaban and apixaban offer: - a fixed dosage regimen - a relatively small potential drug interaction profile - minimal laboratory monitoring - little to no dietary restrictions. Although these agents offer a relatively fixed dose regimen, dosage adjustment is required in moderate renal dysfunction, and use is contraindicated in severe renal dysfunction. Currently there are no specific reversal agents in the event of a nov- el anticoagulant associated bleed. These concerns led to the development of an anticoagulation stewardship program at our institution to monitor and guide the usage of these agents

Surgical Pulmonary Embolectomy Outcomes for Acute Pulmonary Embolism

Introduction: Acute pulmonary embolism (PE) is associated with significant mortality. Surgical embolectomy is a viable treatment option; however, it remains controversial due to variable outcomes. This review investigates patient outcomes following surgical embolectomy for acute PE. Methods: Electronic search was performed to identify articles reporting surgical embolectomy for treatment of PE. 32 studies were included comprising 936 patients. Demographic, perioperative, and outcome data were extracted and pooled for systematic review. Results: Mean patient age was 56.3 [95% CI 52.5; 60.1] years and 50% [46; 55] were male. 82% had right ventricular dysfunction [62; 93], 80% [67; 89] had unstable hemodynamics, and 9% [5; 16] experienced cardiac arrest. Massive PE and submassive PE were present in 83% of patients [43; 97] and 13% [2; 56], respectively. Before embolectomy, 33% of patients [14; 60] underwent systemic thrombolysis and 14% [8; 24] catheter embolectomy. Preoperatively, 47% of patients were ventilated [26; 70] and 36% had percutaneous cardiopulmonary support [11; 71]. Mean operative time and mean cardiopulmonary bypass time were 170 [101; 239] and 56 [42; 70] minutes, respectively. Intraoperative mortality was 4% [2; 8]. Mean hospital and ICU stay were 10 [6; 14] and 2 [1; 3] days, respectively. Mean postoperative systolic pulmonary artery pressure (sPAP) was significantly decreased from preoperative (sPAP 57.8 mmHg [53; 62.7]) to postoperative period (sPAP 31.3 mmHg [24.9; 37.8]), p \u3c0.01). In-hospital mortality was 16% [12; 21]. Overall survival at five years was 73% [64; 81]. Discussion: Surgical embolectomy is an acceptable treatment option with favorable outcomes

The New Oral Anticoagulants for the Treatment of Venous Thromboembolism: A New Paradigm Shift in Antithrombotic Therapy

Background: Several novel oral anticoagulants have been studied for the prevention and treatment of venous thromboembolism (VTE) in different patient populations. Clinicians will increasingly encounter scenarios in which they must choose among these and conventional anticoagulants for the treatment of this potentially fatal condition. Objective: To review the results of Phase III clinical trials that investigated the novel oral anticoagulants for the treatment of deep vein thrombosis and pulmonary embolism. Potential advantages and disadvantages of these anticoagulant agents with respect to each other and conventional therapy will also be explored through a case-based approach. Methods: A literature search in PubMed was conducted that identified Phase III clinical trials investigating the novel oral anticoagulant agents for the treatment of VTE. Results: The new oral anticoagulant agents have been shown to be as safe and effective for the treatment of VTE as conventional therapies. Conclusions: These novel, oral anticoagulant agents are legitimate options for the treatment of VTE. A careful assessment of a patient׳s comorbidities, medication use, and laboratory results should be undertaken before prescribing the new oral anticoagulant agents for patients with VTE

Role of Target Specific Oral Anticoagulation After Operative Management of Venous Thoracic Outlet Syndrome

Background: The purpose of this study is to review the efficacy of Target Specific Oral Anticoagulants (TSOAC) versus vitamin K antagonist (VKA) for post-surgical anticoagulation in patient with primary subclavian vein thrombosis. Rivaroxaban, a factor Xa inhibitor, was the first TSOAC approved by the FDA in 2012 for the treatment and prevention of deep vein thrombosis. However, the efficacy and safety of TSOAC for prevention of recurrent deep vein thrombosis after revascularization of upper extremity compression syndromes is largely unknown.https://jdc.jefferson.edu/surgeryposters/1001/thumbnail.jp
