Implication
May support potential-guided ablation for atriofascicular pathways; hypothesis-generating and requires prospective validation.
Structured PICO
Does radiofrequency catheter ablation guided by discrete electrical potentials eliminate conduction in patients with atriofascicular accessory pathways with Mahaim-like properties?
P
Population
4 patients (3 females, 1 male) with atriofascicular accessory pathways with Mahaim-like properties and preexcited reciprocating tachycardia, mean age 35 years.
I
Intervention
Radiofrequency catheter ablation guided by recording of discrete electrical potentials at the tricuspid annulus
O
Outcome
Elimination of conduction through the atriofascicular accessory pathwaysurrogate
Recording discrete electrical potentials at the tricuspid annulus is a feasible and effective method to guide radiofrequency ablation of atriofascicular accessory pathways.
