Predictors of ERATs
AI-guided PVI, sex, LA diameter, and type of AF were independent predictors of ERAT. It has been reported that the AF duration, non-PAF, history of hypertension, LA enlargement, and lack of an SVC isolation were predictors of ERAT.17 There are few reports about the correlation between ERATs and a female sex. However, several reports have demonstrated that a female sex is a predictor of an arrhythmia recurrence after a PVI. 18,19 We consider that a female sex could be a risk factor of ERAT as well as of a late recurrence.
