About

The goal of this prospective observational study is to learn about the influence of epicardial fat on the success of catheter ablation in patients with atrial fibrillation.

Full description

A volumetric quantification of epicardial fat is examined by dual source cardiac computet tomography in patients with paroxysmal or persistent atrial fibrillation prior to receiving their first catheter ablation for atrial fibrillation. After ablation the recurrence of arrhythmia is examined after 3 and 6 months respectively.

Enrollment: 200 estimated patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Inclusion criteria

• patients with planned catheter ablation due to paroxysmal or persistent atrial fibrillation
• written informed consent
• planned computet tomography

Exclusion criteria

• history of left atrial catheter ablation
• minor patients or patients not capable of giving written informed consent
• contraindication for computet tomography with contrast agents (e.g. allergy to contrast agents or relevant renal insufficiency or hyperthyreosis)
• patients with congenital heart defects or history of cardial surgery
