Key result
Catheter ablation using the EnSite NavX three-dimensional mapping system significantly reduced mean fluoroscopy time compared to matched controls (1.05 vs 21.37 minutes, P < 0.001).
Why the study?
Does three-dimensional mapping reduce fluoroscopy time in pediatric patients undergoing catheter ablation for supraventricular tachycardia?
Cohort (n=30)
Does three-dimensional mapping reduce fluoroscopy time in pediatric patients undergoing catheter ablation for supraventricular tachycardia?
Absolute Event Rate: 1.05% vs 21.37%
p-value: p=< 0.001
The use of 3D mapping systems for catheter ablation in pediatric patients with supraventricular tachycardia can drastically reduce or eliminate the need for fluoroscopy.
No takes yet. Share an insight, caveat, or question.
May enable fluoroscopy-free ablation in select pediatric cases; leaves open generalizability to adults and complex arrhythmias.
Smith et al. (2007) conducted a cohort in Reentrant supraventricular tachycardia (n=30). Three-dimensional mapping system (EnSite NavX) vs. Age-matched and rhythm-matched control population was evaluated on Fluoroscopy time (p=< 0.001). Catheter ablation using the EnSite NavX three-dimensional mapping system significantly reduced mean fluoroscopy time compared to matched controls (1.05 vs 21.37 minutes, P < 0.001).
