From the Guidelines
Eliquis (apixaban) therapy should be continued for at least 45 days after left atrial ligation and clip procedures, as recommended by the 2021 guideline for the prevention of stroke in patients with stroke and transient ischemic attack 1. The duration of Eliquis therapy after left atrial appendage (LAA) ligation and clip procedures is crucial to prevent stroke and ensure proper healing.
- The initial healing period typically requires anticoagulation to reduce the risk of clot formation on the newly placed clip or ligation site.
- Post-procedure imaging, such as a transesophageal echocardiogram (TEE), is necessary to confirm complete LAA closure before discontinuing Eliquis.
- The decision to stop anticoagulation should be based on individual risk factors for stroke, healing progress, and other medical conditions, as determined by a cardiologist.
- Some patients with additional stroke risk factors may need to continue anticoagulation indefinitely, even after successful LAA closure, as recommended by the guidelines for patients with nonvalvular AF and stroke or TIA 1. Key considerations for the duration of Eliquis therapy include:
- The risk of recurrent stroke and the need for anticoagulation to reduce this risk, as outlined in the guidelines 1.
- The potential for bleeding complications and the need to balance this risk with the benefits of anticoagulation.
- The importance of regular follow-up appointments and imaging tests to monitor healing progress and verify successful LAA closure.
From the Research
Duration of Eliquis after Left Atrial Ligation and Clip
- The duration of Eliquis (apixaban) after left atrial ligation and clip is not explicitly stated in the provided studies 2, 3, 4, 5, 6.
- However, study 2 mentions that anticoagulant could be discontinued in all patients after the clip-and-loop technique using an AtriClip, with no patient having a thrombus at the edge of the clip or communication into the left atrial appendage 3 months after surgery.
- Study 3 states that patients did not receive transition oral anticoagulation therapy post-LAA ligation, and instead received aspirin only, clopidogrel only, aspirin plus clopidogrel, or no antithrombotic drugs.
- Study 6 reports that 76 (78%) of patients were on presurgical oral anticoagulation, whereas 5 (5.1%) were on postprocedure oral anticoagulation, with no postoperative thromboembolic events at the time of the study transesophageal echocardiography.
Anticoagulation Management
- The management of anticoagulation after left atrial ligation and clip may vary depending on individual patient factors and institutional protocols 5.
- Study 4 examines the risk of stroke or systemic embolism in patients with atrial fibrillation and the effect of apixaban versus warfarin, but does not specifically address the duration of Eliquis after left atrial ligation and clip.
- Overall, the provided studies suggest that left atrial appendage ligation and clip can be an effective procedure for reducing the risk of embolic events in patients with atrial fibrillation, but the optimal anticoagulation management strategy after the procedure is not clearly defined 2, 3, 6.
