New irrigation catheter does not reduce silent cerebral lesions after PVI; leaves open whether design changes affect embolic risk.
Does a new irrigation design catheter reduce silent cerebral lesions compared to a standard irrigated catheter in patients undergoing pulmonary vein isolation for paroxysmal atrial fibrillation?
A new irrigation design catheter for PVI did not significantly reduce the risk of silent cerebral lesions compared to a standard catheter, though it reduced saline volume infusion.
Scaglione et al. (2012) studied this question.
