Key result
Slit-based irrigation catheters linked to ~89% fewer procedure-related ischemic complications versus non-slit catheters.
Why the study?
Laser-cut slit-based irrigation catheters have a unique design to cool the tip more efficiently, but their safety regarding prevention of procedure-related ischemic complications in AF patients undergoing RFCA needed assessment.
Do slit-based irrigation catheters reduce procedure-related ischemic complications compared to non-slit-based or non-irrigation catheters in patients with atrial fibrillation undergoing radiofrequency catheter ablation?
Cohort (n=3,120)
No
Do slit-based irrigation catheters reduce procedure-related ischemic complications compared to non-slit-based or non-irrigation catheters in patients with atrial fibrillation undergoing radiofrequency catheter ablation?
Absolute Event Rate: 0.08% vs 0.71%
p-value: p=0.009
Slit-based irrigation catheters significantly reduce the risk of procedure-related ischemic stroke and TIA compared to hole-based irrigation catheters during atrial fibrillation ablation.

May support slit-based catheter preference in AF ablation; hypothesis-generating and requires randomized confirmation.
Kim et al. (2020) conducted a cohort in Atrial fibrillation (n=3,120). Slit-based irrigation catheters vs. Non-slit-based irrigation catheters and non-irrigation catheters was evaluated on Procedure-related ischemic complication (ischemic stroke or TIA within 30 days after RFCA) (p=0.009). Slit-based irrigation catheters were superior to non-slit-based irrigation catheters in preventing procedure-related ischemic complications at 30 days (0.08% vs. 0.71%; p=0.009).
