Now, and then, we simply ablate circles around the orifices of the pulmonary veins. This works reasonably well. But we don’t—exactly—know why it works. For instance, some patients have total elimination of AF, but when they are restudied, they have reconnection of PV activity. Observations like these suggest there is something else happening with our ablations—beyond building an electric fence around the veins.One possibility is that...
