Additional value of left atrium remodeling assessed by three-dimensional echocardiography for the prediction of atrial fibrillation recurrence after cryoballoon ablation

Research output: Contribution to journalArticlepeer-review

Abstract

Background/Introduction: Cryoballoon ablation (CBA) is a safe and efficient therapeutic option for atrial fibrillation (AF). However, AF recurrence rate remains up to 25-30%, leading to repeated ablations and increased rates of complications. Previous reports on the role of left atrial (LA) size assessed by two-dimensional echocardiography (2DE) to predict AF recurrence showed controversial results. 2DE implies geometrical assumptions of the LA remodeling, which is a three-dimensional process. Purpose: The purpose: of this study was to evaluate the additional value of LA remodeling assessed by three-dimensional echocardiography (3DE) to predict AF recurrence after CBA. Methods: Consecutive patients with paroxysmal/persistent AF undergoing CBA were prospectively included. Echocardiography was performed before CBA. The primary endpoint was AF recurrence after the blanking period (3 months). Results: One hundred seventy-two patients (62.2 ± 12.2 years, 61% male) were included in the analysis. Fifty (29%) patients had AF recurrence after the blanking period. 3DE LA maximum volume index (LAVI) had the highest incremental predictive value for AF recurrence (HR 5.50, 95% CI 1.34-22.45, p
