May shorten PVI procedures via 8-mm ostial targeting; hypothesis-generating and requires randomized confirmation before practice change.
Does a fixed distance of 8 mm to the PV ostia reduce the requirement of carina ablation and procedure time in patients undergoing circumferential PVI for paroxysmal AF?
Maintaining a fixed distance of 8 mm to the PV ostia during circumferential PVI reduces the need for additional carina ablation and shortens procedure time.
