Repeat procedure
The redo-procedure was performed 1.1 year after the initial procedure
(13.2±3.5 years, and 14.3±4.3 years). During the redo procedures, a
combination of long sheath and radiofrequency energy was selected in all
cases. Moreover, in 4 cases (57%) irrigated tip catheter s and 3D
mapping were selected. The redo ablation was acutely successful in all
cases. Figure 5 and 6 depict two examples of patients with
Mahaim accessory pathways.
