TI  - Evaluation of factors affecting persistence of atrial fibrillation in patients 
      with concomitant atrial flutter treated with percutaneous radiofrequency current 
      ablation of the right atrial cavotricuspid isthmus.

AB  - BACKGROUND: Atrial fibrillation (AF) and atrial flutter (AFL) often coexist. In 
      some patients, AF remission is seen after successful percutaneous radiofrequency 
      current ablation of the cavotricuspid isthmus (CTI). AIM: To evaluate factors 
      affecting AF remission in patients with typical AFL and concomitant AF who 
      underwent CTI ablation. METHODS: The study included consecutive 69 patients with 
      typical AFL and concomitant clinically documented AF who underwent successful CTI 
      ablation in 2003-2010. Based on the follow-up data from medical records and 
      telephone interviews, the patients were divided into two groups: with persistent 
      AF (group A) and with remission of AF (group B). This distinction was based on 
      arrhythmia symptoms reported by the patient, such as palpitation or irregular 
      heartbeat, and confirmed electrocardiographically (12-lead ECG or Holter 
      monitoring). RESULTS: Group A included 47 patients, and group B included 22 
      patients. The two groups did not differ significantly in regard to the New York 
      Heart Association (NYHA) functional class and concomitant diseases including 
      diabetes, ischaemic heart disease, previous myocardial infarction and arterial 
      hypertension. The two groups also did not differ by echocardiographically 
      determined mean left ventricular ejection fraction (LVEF) and left atrial 
      dimension (43.5 +/- 9.27 vs. 39.27 +/- 5.76, p = 0.075). Multivariate logistic 
      regression did not identify any independent risk factors of AF persistence after 
      CTI ablation. Univariate logistic regression also did not show arterial 
      hypertension, type 2 diabetes, previous myocardial infarction, LVEF, left 
      ventricular dimension or age to affect AF persistence after successful ablation. 
      CONCLUSIONS: Based on the results of our study, we were unable to identify 
      factors determining remission of AF coexisting with AFL in patients after 
      percutaneous CTI ablation. These findings may indicate the need for complex 
      ablation procedure (involving both CTI and pulmonary venous ostia ablation) in 
      patients in whom these two arrhythmias coexist.
