AF is progressive is nature, with longer diagnosis-to-ablation times associated with markers of atrial remodelling2.
For patients with symptomatic paroxysmal AF, antiarrhythmic drugs (AAD) are often prescribed as the first-line therapy. However, these drugs fail to prevent AF recurrence in up to 50% of patients3. Some of these patients go on to receive catheter ablation.
Importantly, prior studies suggest that a shorter diagnosis to ablation time is associated with lower rates of atrial arrythmia recurrence, repeat procedures, and cardiovascular hospitalisation4-7. These observations paired with evidence that catheter ablation can halt AF progression more effectively than AAD therapy7 has sparked debate around the optimal first line therapy for symptomatic AF patients.
The positive results from the Cryo-FIRST study demonstrate Cryoballoon ablation is safe and superior to AAD therapy in reducing AF recurrence in this first line patient population1.
