Low-voltage areas, atrial cardiomyopathy score, and outcomes in patients with preserved ejection fraction after catheter ablation of atrial fibrillation.

ABSTRACT:

Background

Left atrial low-voltage areas (LVAs) and the postprocedural atrial cardiomyopathy (AC) score-which incorporates echocardiographic data and brain natriuretic peptide levels-are linked to outcomes in patients undergoing catheter ablation of atrial fibrillation (AF). However, voltage mapping requires considerable time and cost, and the optimal prognostic predictor for patients with preserved left ventricular ejection fraction (LVEF) after AF ablation remains unclear.

Objective

This study analyzed the relationship between LVAs, the AC score, and outcomes among patients with preserved LVEF after AF ablation.

Methods

We retrospectively analyzed 270 patients with preserved LVEF who underwent AF ablation. Blood tests and transthoracic echocardiography were performe
