@nevets True, at least insofar as the research suggests, but that reduced catheter dwell time doesn't translate into improved outcomes....not yet. Maybe they need to rethink the dwell time, in which case there may eventually be no advantage over RF in terms of the risks to the phrenic nerve and to the esophagus, and also to the Vagus nerve (which I didn't mention earlier). We'll see eventually.

I just read a report that PFA also causes an acute reduction in blood pressure but mostly when the left superior PV is ablated with its first one or two applications. The other PVs are not affected, and each subsequent application in circulation around those veins doesn't show any further drop in BP. One center, one set of data, but it bears more scrutiny.
