This study revealed that slit-based irrigation catheters can be
effective in preventing procedure-related ischemic complication.
Non-irrigation catheters showed highest risk for procedure-related
ischemic complication and peri-procedural anticoagulation did not
influence the risk for procedure-related ischemic complication. This
data is the largest study to date analyzing safety issue of different
irrigation systems and the first report demonstrating that irrigation
systems can affect actual clinical stroke and TIA.
