A total of 54 referrals, mainly atrial fibrillation (33 patients) and ventricular tachycardia (11 patients), were referred for complex arrhythmia ablation therapy abroad. We aim to assess arrhythmia recurrence post-arrhythmia ablation and the treatment prescribed, with recurrence on or off antiarrhythmic treatment with or without referral for re-do ablation and recurrence free rates.
The types of ablations; namely AF (Atrial Fibrillation) ablation with PVI (Pulmonary Venous Isolation)/ PVI with substrate modification and VT (Ventricular tachycardia) ablation, the anti-arrhythmic treatment prescribed, repeat ablations and recurrence free rates despite or off anti-arrhythmic treatment – were noted.
Pharmacological treatment and arrhythmia recurrence. Note: Class refers to the class of the antiarrhythmic, Rx: treatment
Arrhythmia recurrence rates in the patients referred abroad for ablative therapy during the period between 2010-2015 are relatively high. The Maltese cohort had comparatively more advanced disease with RF ablation being generally considered only as a final attempt in the management strategy. This supports the implementation of a local catheter ablation programme for complex arrhythmias.
