Guiding atrial fibrillation ablation combined with left atrial appendage occlusion procedure by fluoroscopy with or without transesophageal echocardiography achieved comparable outcomes.

ABSTRACT:

Background

Atrial fibrillation (AF) is the most common arrhythmia and can be treated with catheter ablation (CA) combined with left atrial appendage occlusion (LAAO). The study is designed to compare the safety and efficacy of guiding the combined procedure by digital subtraction angiography (DSA) with or without transesophageal echocardiography (TEE).

Methods

From February 2019 to December 2020, 138 patients with nonvalvular AF who underwent CA combined with LAAO procedure were consecutively included, and two cohorts were built according to intraprocedural guidance (DSA or DSA with TEE). Periprocedural and follow-up outcomes were compared with investigate the feasibility and safety between the two cohorts.

Results

71 patients and 67 patients were included in the DSA
