This case report demonstrates that mechanical pressure from a catheter at a CFAE site can terminate persistent atrial fibrillation.
May indicate mechanical AF termination at remote CFAE; hypothesis-generating observation requiring prospective validation.
Termination of Persistent AF During Mapping. Complex fractionated atrial electrograms (CFAEs) may represent critical areas for the maintenance of atrial fibrillation (AF). While AF organization and termination have been reported with CFAE ablation, no reports of arrhythmia termination during left atrial mapping exist. We report a case of reproducible AF termination with catheter pressure at a site of CFAE remote from the site of AF.
