What techniques are available for catheter ablation procedures?
Radiofrequency point-by-point ablation, cryoballoon ablation and laser ablation are the techniques available for catheter ablation procedures. Radiofrequency multi-electrode was not included as an alternative due to its lower efficacy relative to cryoballoon and laser ablation and concerns about a higher risk of stroke. Radiofrequency point-by-point ablation is the most cost-effective option, while cryoballoon ablation may be quicker to perform, with same-day discharge more likely. Laser ablation may be more suitable for some patients because it can sometimes be carried out without general anaesthesia. Ablation may be considered for those with persistent symptoms that are not alleviated by, or who cannot have, antiarrhythmic drugs.
