[Surgical radiofrequency catheter ablation of accessory pathways in Ebstein's anomaly].
Thirteen patients with Ebstein anomaly and atrioventricular reentrant tachycardia and at least one accessory pathway were included in this study. One accessory pathway in 7 (53.8%) patients and multiple accessory pathways in 6 (46.1%) were found. Mahaim accessory pathway was observed in 5 (38.4%) patients. A total of 22 accessory pathways was found, 2 (9%) were concealed. In all (100%), the accessory pathways were located in the tricuspid ring. The most frequent regions were right lateral free wall with 11 (50%) and 5 right posteroseptal (22.7%). Ten patients underwent surgical radiofrequency catheter ablation and three subjected to surgical section. We obtained success in 100%. No complications were observed during the procedures. In conclusion, surgical ablation therapy in patients with accessory pathways and Ebstein's anomaly is safe and effective.
