High left atrial pressures are associated with advanced electroanatomical remodeling of left atrium and independent predictors for clinical recurrence of atrial fibrillation after catheter ablation

Elevated LAP was closely associated with electroanatomical remodeling of the LA and was an independent predictor for recurrence after AF ablation. PV diastolic flow velocity and E/Em can be used as a noninvasive parameter predicting high LAPpeak(SR) in patients with AF.
