Performing catheter ablation for atrial flutter while patients are on oral anticoagulation is safe. This study found a low risk of complications, including bleeding and thromboembolic events, during the procedure.
Area of Science:
- Cardiology
- Electrophysiology
Background:
- Catheter ablation is a common treatment for atrial flutter.
- Oral anticoagulation is often necessary for patients undergoing ablation due to other risk factors.
Purpose of the Study:
- To assess the safety of performing catheter ablation for common atrial flutter in patients concurrently taking oral anticoagulants.
- To determine the incidence of thromboembolic and bleeding complications in this patient group.
Main Methods:
- A consecutive series of 102 patients with common atrial flutter undergoing cavo-tricuspid isthmus ablation were included.
- All patients were maintained on oral anticoagulants for at least 3 weeks prior to the procedure.
- Various oral anticoagulants were used, including acenocoumarol, dabigatran, rivaroxaban, and apixaban.
Main Results:
- No new pericardial effusions or major complications were observed post-ablation.
- A low rate of mild hematoma at the puncture site (7.8%) was the primary complication.
- The study included a diverse group of patients with a mean age of 67.9 years, predominantly male (83.3%).
Conclusions:
- Catheter ablation for common atrial flutter can be safely performed in patients maintained on oral anticoagulation.
- The risk of significant complications, such as major bleeding or thromboembolic events, appears low.
