Initial procedure
All patients presented with post-procedure recurrence (n=7, 18%), with
3 (42%) presenting with Mahaim fibers. The main reason for recurrence
seemed to be inadequate lesion formation due to lack of catheter
stability in 5 (72%). Interestingly, a long sheath was used in only 1
(14%) case during the initial procedure while an irrigated catheter was
preferred in 3 (43). Overall, this group experienced the longest
fluoroscopy times and ablation times.
