B-29 | Incidence of Atrial Fibrillation and Arrhythmias in Six Closure Devices for Patent Foramen Ovale

Abstract

Patients with a patent foramen ovale (PFO) who undergo percutaneous PFO closure are at a greater risk of developing atrial fibrillation (AF) compared to patients whose PFOs are managed medically. Post-closure AF appears to be well tolerated if treated, but could theoretically increase the risk for stroke. Post-closure AF is reported to occur in 3.7% of patients, however, incidence across devices remains uncertain. This study aims to evaluate the frequency of post-closure AF and arrhythmias in 6 PFO closure devices.
