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.
