A recent article published in Heart looked at the safety and effectiveness of catheter ablation for the treatment of Atrial Fibrillation in patients with HCM by performing a systematic review of prior publications on the subject.

The researchers concluded that even though the success rate for HCM patients was approximately half that of patients who suffered from AFib but did not have HCM, catheter ablation is still an effective treatment for HCM patients;  especially for those HCM patients who suffer from paroxysmal AFib and who have smaller atria.
