I don’t understand the desire for (right) flutter ablation with large single shot PFA. It’s not as if safe and efficient CTI ablation is an unmet need in EP. Clearly spasm is not innocent, as this data also shows. Reminds me of cryoballoon ablation of the posterior wall which I’ve often compared to trying to open a bottle of wine with a fork: it may be the only tool you have at hand at a given moment trying to achieve a particular goal and sure, it’s doable if you are desperate enough. That doesn’t make it a particularly bright idea though.
