title: [Predictors of functional tricuspid regurgitation (TR) in atrial fibrillation (AF) patients and the impact of radiofrequency catheter ablation of AF on functional TR].
abstract: OBJECTIVE
  This study examined the hypothesis that correction of AF with catheter ablation can improve FTR.
  
  
  METHODS
  Two groups who underwent catheter ablation of atrial fibrillation were compared (From March 2012 to April 2013): 44 patients with FTR; and 44 patients with no or less FTR. To find the predictors of functional tricuspid regurgitation (FTR) in atrial fibrillation patients and assess the effect of catheter ablation on FTR.
  
  
  RESULTS
  In multivariable regression analysis, RA size (OR: 1.377, 95% CI 1.150-1.649, P=0.001) and age (OR: 1.093, 95% CI 1.007-1.185, P=0.03) were associated with FTR. The primary end point was achieved in 54.5% (24/44) of patients with FTR, and 59.1% (26/44) in norml ones (P>0.05). Recurrence (OR: 0.53, 95% CI 0.008-0.331, P=0.002) was the only factor related to unimproved FTR after ablation.
  
  
  CONCLUSIONS
  FTR is associated with advancing age and RA dimension; catheter ablation of AF in FTR patients is effective and safe; FTR will be significantly improved in patients maintaining sinus rhythm after catheter ablation of AF.
