Procedural considerations
An index CRYO approach may offer several advantages over RF based index ablation. Compared to RF ablation, Cryoablation is generally considered a simplistic and more streamlined and standardized approach to AF ablation, requiring fewer resources23 and an arguably a less steep learning curve compared to RF ablation. The effectiveness of this ablation approach in patients with heart failure, may help to expand access to catheter ablation beyond specialised tertiary centres, potentially facilitating earlier treatment. Despite the complexity of patients in this cohort (average CHADS2VASC score of 2.7, and average LVEF of 34%, coronary disease in over a third) – patients had a significant improvement in ventricular function and heart failure symptoms5. The shorter more streamlined approach offered by cryoablation may potentially offer an advantage in the heart failure population.
