Key result
A simple statistical model incorporating arrhythmia mechanism and structural congenital heart disease accounted for ~71% of the variance in acute ablation failure rates across 19 centers.

Supports adjusted benchmarking of ablation outcomes across centers; leaves open whether models improve patient selection or long-term results.
Observational (n=4,486)
Yes
A simple statistical model incorporating arrhythmia mechanism and structural heart disease can effectively adjust for case mix when comparing acute ablation failure rates across pediatric centers.
Triedman et al. (2013) conducted an observational in Pediatric and congenital heart disease requiring catheter ablation (n=4,486). Catheter ablation was evaluated on Acute ablation failure and serious adverse event rates. A simple statistical model incorporating arrhythmia mechanism and structural congenital heart disease accounted for ~71% of the variance in acute ablation failure rates across 19 centers.
