Key result
Left-sided radiofrequency ablation of the His bundle significantly reduced procedure duration compared to the right-sided approach (5-10 vs 22-90 minutes, P<0.005) and successfully created AV block.
Why the study?
Does a left-sided approach improve procedural success and reduce procedure time compared to a right-sided approach for radiofrequency ablation of the His bundle in patients with atrial flutter or fibrillation?

May shorten His bundle ablation after right-sided failure; leaves open need for randomized trials before practice change.

p-value: p=< 0.005
A left-sided retrograde arterial approach for His bundle ablation significantly reduces procedure time and successfully creates AV block even when the conventional right-sided approach fails.
Souza et al. (1992) conducted an observational in Atrial flutter or fibrillation (n=30). Left-sided radiofrequency ablation vs. Right-sided radiofrequency ablation was evaluated on Procedure duration (p=< 0.005). Left-sided radiofrequency ablation of the His bundle significantly reduced procedure duration compared to the right-sided approach (5-10 vs 22-90 minutes, P<0.005) and successfully created AV block.
