Radiofrequency catheter ablation of Mahaim fibers at the tricuspid annulus.
Key result
Radiofrequency catheter ablation at the tricuspid annulus safely eliminated accessory pathway conduction and prevented tachycardia recurrence in all 4 patients over a mean 8-month follow-up.

Structured PICO
Does radiofrequency catheter ablation at the tricuspid annulus safely eliminate tachycardia in patients with Mahaim fibers?
P
Population
4 patients (mean age 27 years) with Mahaim fibers and highly symptomatic preexcited reciprocating tachycardia who underwent radiofrequency catheter ablation, followed for a mean of 8 months.
I
Intervention
Radiofrequency catheter ablation at the tricuspid annulus (mean 15 pulses)
O
Outcome
Elimination of accessory pathway conduction and prevention of tachycardia recurrence
Radiofrequency catheter ablation at the tricuspid annulus is a feasible, safe, and effective method for eliminating tachycardia in patients with Mahaim fibers.
Cite This Study
Klein et al. (1993) conducted a case report in Mahaim fibers and preexcited reciprocating tachycardia (n=4). Radiofrequency catheter ablation was evaluated on Elimination of accessory pathway conduction and tachycardia recurrence. Radiofrequency catheter ablation at the tricuspid annulus safely eliminated accessory pathway conduction and prevented tachycardia recurrence in all 4 patients over a mean 8-month follow-up.
