# SUPPLEMENTARY INFORMATION:

## I. Background

Atrial fibrillation (AF) is a complex arrhythmia of the heart. Its precise mechanisms remain unclear. This draft guidance describes elements of suggested clinical study design for surgical ablation devices used to treat patients with longstanding persistent AF and patients with symptomatic paroxysmal AF, such as inclusion and exclusion criteria and assessment of effectiveness, which may differ for these patient populations.

## II. Significance of Guidance

This draft guidance is being issued consistent with FDA's good guidance practices regulation (21 CFR 10.115). The draft guidance, when finalized, will represent the agency's current thinking on clinical study designs for surgical ablation devices for treatment of atrial fibrillation. It does not create or confer any rights for or on any person and does not operate to bind FDA or the public. An alternative approach may be used if such approach satisfies the requirements of the applicable statute and regulations.
