PURPOSE OF THE RESEARCH: To identify clinical factors associated with the probability for each arrhythmic mechanism causing recurring symptoms after @entity2917 ( @entity2917 ) ablation. Slow pathway radiofrequency ablation is used to treat @entity2917 . After ablation, recurrence of symptoms due to @entity2917 or other @entity943 can occur. RESULTS: We studied 835 @entity1 successfully treated with @entity2917 ablation. Variables associated with each specific @entity943 underlying symptom recurrence were studied by logistic regression. During a mean follow-up of 2.2  2years, 136 (16%) @entity1 had a recurrence of symptoms. Following invasive and non-invasive studies, symptoms were mostly attributed to @entity7129 , recurrence of @entity2917 and @entity943 (respectively 4.7%, 5.2% and 6.1%). Older age and history of @entity955 were associated with a markedly increased risk of symptom recurrence due to @entity943 (OR=15.58, 7.09-35.22, p<0.001) whereas younger age was associated with a higher risk of @entity7129 . A simple 3-item clinical score based on age categories and @entity955 history efficiently predicted @entity943 (C-Index=0.82, 0.75-0.89) and @entity7129 (C-Index=0.83, 0.75-0.90). 8.3% of @entity1 with scores=0 had @entity943 whereas 100% of @entity1 with scores >= 4 had @entity943 . CONCLUSIONS: While recurrence of symptoms after successful @entity2917 ablation is relatively frequent (16%), true @entity2917 recurrence accounts for only 1/3 of these recurrences. A simple clinical score based on age and history of @entity955 enables efficient risk stratification for symptom recurrence attributable to @entity13610 .
