Prognostic implication of left atrial strain in patients experiencing early recurrence of atrial fibrillation after totally thoracoscopic ablation.

ABSTRACT:

Background

Although early atrial fibrillation (AF) events during the blanking period after AF ablation are risk factors for late recurrence, data on predictors of late recurrence in patients who experience early AF events are limited. In this study, we investigated the implications of left atrial (LA) strain with respect to long-term outcomes in patients experiencing early AF during the blanking period after totally thoracoscopic ablation (TTA).

Methods

A total of 128 patients who underwent TTA between 2012 and 2015 were enrolled from a tertiary center. Peak longitudinal LA strain was measured preoperatively. Early recurrence (ER) was defined as any AF within the 3-month blanking period after TTA. The primary outcome was late recurrence of AF for 5 years, detected on 12-lead
