Catheter ablation provides an effective cure for @entity1 with typical @entity956 . However, these @entity1 may have the potential to develop @entity4710 other than common @entity956 . This study examines clinical and echocardiographic predictors for the occurrence of uncommon @entity956 or @entity955 after abolition of common @entity956 . The study population comprised 17 @entity1 (12 @entity1 , 5 @entity1 , age 32-74 years) who underwent successful radiofrequency catheter ablation of common @entity956 . Common @entity956 did not recur in any @entity1 during a median follow-up time of 8 (range 1-25) months. Within a median of 7 (range 1-223) days, however, symptomatic @entity4710 occurred in 8 of 17 @entity1 (47%): uncommon @entity956 (n = 4); @entity955 (n = 3); and both uncommon @entity956 and @entity955 in one @entity1 . Preablation left atrial volume was significantly larger in @entity1 who developed secondary @entity943 compared with @entity1 who remained in sinus rhythm (57.9 +/- 15.6 vs 43.7 +/- 16.4 cm3, P < 0.05). Enlarged left atrial volume dichotomized at 51 cm3 independently predicted postablation @entity943 (X2 = 5.11, rel. risk = 5.3, P < 0.05). On Kaplan-Meier analysis, time to occurrence of postablation @entity943 was significantly shorter in @entity1 with enlarged left atrium (P < 0.02). In conclusion, symptomatic uncommon @entity956 and @entity955 develops in a substantial proportion of @entity1 after successful ablation of common @entity956 . Out of a series of clinical and echocardiographic parameters, preablation left atrial size is the best predictor for the occurrence of these postablation @entity943 .
