Atrial fibrillation catheter ablation has gained a significant role in the management of the frequent arrhythmia and has been shown to be safe and effective. As with many other interventional therapies, gender bias is present and females are referred for catheter ablation less frequently than their male counterparts. Women referred for catheter ablation tend to be older, more symptomatic, have failed more antiarrhythmic agents and may have poorer procedure success and increased vascular complication rates. Efforts to close this referral gap are clearly needed and it is likely that early referral will reduce gender differences in atrial fibrillation catheter ablation success rates.
