Peri-Procedural Anticoagulation and Imaging
Catheter ablation was performed with minimal interruption of anticoagulation. Warfarin was continued throughout the peri-operative period. DOAC therapy was either uninterrupted, or a single DOAC dose was held prior to ablation. After ablation, all patients received anticoagulation for a minimum of 3 months.
Unless clinically contraindicated, patients had either CT or transesophageal echocardiography (TEE) immediately prior to ablation in order to exclude LAA thrombus. Data collected during electroanatomic mapping (EAM) was merged with pre-acquired CT or MRI at the operator’s discretion.
