Key result
Left atrial appendage thrombi can occur despite adequate therapeutic anticoagulation prior to cardioversion in patients with atrial fibrillation.
Why the study?
Does therapeutic anticoagulation for at least 3 weeks prevent left atrial appendage thrombus in patients with atrial fibrillation prior to cardioversion?
Case Report
Does therapeutic anticoagulation for at least 3 weeks prevent left atrial appendage thrombus in patients with atrial fibrillation prior to cardioversion?
LAA thrombi can persist despite 3 weeks of therapeutic anticoagulation, suggesting TEE may be warranted prior to cardioversion to enhance safety.
No takes yet. Share an insight, caveat, or question.
May warrant TEE before cardioversion despite therapeutic anticoagulation; challenges guidelines and leaves open need for prospective validation.
Florea et al. (2013) conducted a case report in Atrial fibrillation and heart failure. Therapeutic anticoagulation was evaluated on Presence of thrombi in the left atrial appendage. Left atrial appendage thrombi can occur despite adequate therapeutic anticoagulation prior to cardioversion in patients with atrial fibrillation.
