BACKGROUND: Atrial remodelling in @entity120 ( @entity120 ) may lead to higher incidence of @entity943 ( @entity943 ). The purpose of this study was to evaluate the efficiency and safety of various methods for treatment of @entity943 in this group. METHODS: This was a single centre study. Forty-eight @entity1 (33 @entity1 and 15 @entity1 ) aged 19-77 years (median 49 years) were enrolled. There were 30 @entity1 with idiopathic @entity120 , 10 had @entity120 associated with connective tissue disease, and eight with @entity299 . A retrospective analysis was performed to estimate the prevalence and type of @entity943 , as well as efficiency and safety of treatment methods. Mean follow-up period was 28.8  17.7 months. RESULTS: @entity943 occurred in 17 @entity1 (35%) and appeared to be @entity955 , @entity5069 or @entity591 . @entity943 coexisted with elevated mean right atrial pressure in 75%. Four @entity1 had more than one type of @entity943 . A @entity5069 -like macro-reentrant form of @entity591 dependent on cavo-tricuspid isthmus was found in four cases. The treatment of @entity943 included typical methods: antiarrhythmic drugs, direct current cardioversion (DCC), and radiofrequency (RF) ablation. All of the therapeutic methods were effective in managing acute @entity943 . Three @entity1 required re-ablation. Overall mortality: 14 @entity1 (29%) in the whole study group, including six in @entity943 group (35%) and eight without @entity943 (26%). CONCLUSIONS: In @entity1 with @entity120 DCC, pharmacological cardioversion and RF ablation can be applied safely and effectively. Flutter-like macro-reentrant @entity591 dependent on cavo-tricuspid isthmus is observed in this group. It is more challenging, but possible, to successfully treat this @entity943 with RF ablation.
