Key result
A continuous warfarinization strategy during atrial fibrillation ablation resulted in similar rates of hemorrhagic complications (18.2% vs 18.4%) compared to switching to heparin.
Why the study?
Does a continuous warfarinization strategy improve safety and convenience compared to switching to heparin in patients undergoing catheter ablation of atrial fibrillation?
Cohort (n=104)
Does a continuous warfarinization strategy improve safety and convenience compared to switching to heparin in patients undergoing catheter ablation of atrial fibrillation?
Absolute Event Rate: 18.2% vs 18.4%
p-value: p=NS
Continuous warfarinization during atrial fibrillation ablation maintains stable INR without increasing hemorrhagic complications compared to bridging with heparin.
No takes yet. Share an insight, caveat, or question.
Continuous warfarinization was associated with similar bleeding risk; leaves open confirmation of safety and convenience in AF ablation.
Kwak et al. (2009) conducted a cohort in Atrial fibrillation undergoing radiofrequency catheter ablation (n=104). Continuous warfarinization strategy vs. Switching to heparin strategy was evaluated on Hemorrhagic complications (p=NS). A continuous warfarinization strategy during atrial fibrillation ablation resulted in similar rates of hemorrhagic complications (18.2% vs 18.4%) compared to switching to heparin.
