Key result
Catheter ablation for drug-refractory atrial fibrillation in hypertrophic cardiomyopathy achieved 1-year AF elimination in 62% and AF control in 75% of patients.
Why the study?
Does catheter ablation improve AF elimination and control in patients with hypertrophic cardiomyopathy and drug-refractory AF?
Cohort (n=33)
Does catheter ablation improve AF elimination and control in patients with hypertrophic cardiomyopathy and drug-refractory AF?
Catheter ablation for drug-refractory AF in patients with HCM yields favorable outcomes, with 1-year AF control achieved in 75% of patients, though efficacy is reduced in those with persistent AF, larger left atria, and advanced diastolic dysfunction.

May support ablation for refractory AF in HCM; leaves open randomized confirmation of benefit.
Bunch et al. (2008) conducted a cohort in Hypertrophic cardiomyopathy with drug-refractory atrial fibrillation (n=33). Catheter ablation was evaluated on 1-year survival with AF elimination (95% CI 66-84). Catheter ablation for drug-refractory atrial fibrillation in hypertrophic cardiomyopathy achieved 1-year AF elimination in 62% and AF control in 75% of patients.
