Case: A 62-year-old woman was referred for atrial fibrillation (AF) ablation. She had permanent AF for 8 years since mechanical mitral valve replacement for rheumatic heart disease. EPS: A strategy of substrate-based ablation targeting areas of complex fractionated atrial electrograms (CFAE) was pursued. These sites were identified by inspection of electrograms and verified with software-based electrogram analysis, with the left atrial roof demonstrating the highest density of CFAE sites. Successful catheter ablation was performed. The patient has remained free of recurrence over 4 months of follow-up. Discussion: This case presents a successful ablation procedure using the emerging strategy of CFAE-targeted ablative lesions. Given the patient�s permanent AF and mechanical mitral valve, the high density of CFAE sites on the left atrial roof was an unexpected finding. Analysis for CFAE sites guided the procedure in a direction that might otherwise not have been undertaken, leading to a successful ablation. |
