@sjm46 The point is that it does not have a 85% success rate because, as the citation says, it is no better (currently) than RF, and RF ablation only has a 75% success rate (some sources saying it is lower, closer to 68%). If RF has a 70-75% success rate, and the citation is correct, that PFA is not significantly (statistically) superior to RF, then PFA cannot have an 85% success rate. QED.

This study is actually quite dismal, indicating only 56% success for first ablations:

This one says it's closer to 90%:

Whatever you want to pin it at, say an average of about 75%, the first citation in the previous post says that PFA is not statistically more efficacious than RF. What PFA does have is less risk due to less tissue damage, or potential damage to the phrenic nerve and to the esophagus. That, alone would make PFA more desirable for the majority of patients. Just don't expect to be AF-free at a rate higher than RF, where the failure rate runs at about 25%.
