The aim of this retrospective study was to assess short and long-term mortality and morbidity after radiofrequency ablation of the @entity713 in @entity1 with @entity943 resistant to treatment. This cooperative series included 91 @entity1 (47 @entity1 , mean age 68 +/- 9 years). The @entity943 was paroxysmal in 56% of cases. The mean duration of symptoms was 67 +/- 61 months and 45 @entity1 (49.4%) were in the NYHA Classes III and IV. An escape rhythm was present in 58 @entity1 with a mean frequency of 39 +/- 9/min. Early complications were observed in 5 @entity1 ( @entity1150 , @entity1151 , mild @entity2294 and haemothorax). The hospital mortality was 4 @entity1 (4.4%). Death was of cardiac origin in 1 case ( @entity712 ). The mean follow-up of @entity1 was 14.5 +/- 8.6 months. Eleven @entity1 died during this period, 8 of cardiac causes: @entity712 (3 cases), @entity944 (3 cases), @entity715 of a valve prosthesis (1 @entity1 ) and major electrolyte disturbances causing loss of stimulation in 1 case. Six @entity1 had recurrences. Long-term morbidity was either related to cardiac pacing (3 cases) or @entity712 (3 cases). Thirteen @entity1 were in NYHA Classes III or IV at the end of follow-up. The authors conclude that radiofrequency ablation at the @entity713 is an effective method of treating resistant @entity943 . Complications are not frequent but mortality appears to be high, probably due to the presence of advanced @entity299 in the majority of cases. @entity944 seems to be rare and unrelated to pacing defects.
