Clinically apparent long-term electric disturbances in the acute and very long-term of patent foramen ovale device-based closure.

Background/purpose: Incidence of electrical disturbances in patients submitted to transcatheter patent foramen ovale (PFO) closure has not been fully clarified in a large population. The aim of the study is to assess the incidence of atrial fibrillation, supraventricular tachi-arrhythmias, and atrio-ventricular block in the acute and very long-term follow-up.

Methods/materials: We reviewed the medical and instrumental data of 1000 consecutive patients (mean age 47.

Long-Term Outcomes and Complications of Intracardiac Echocardiography-Assisted Patent Foramen Ovale Closure in 1,000 Consecutive Patients.

Backgrounds: Long-term fate of patients submitted to patent foramen ovale (PFO) closure is still unclear. The aim of the study was to evaluate the incidence of atrial fibrillation (AF), aortic or atrial free wall erosion, device thrombosis (DT), new onset or worsening of mitral valve regurgitation (MVR), and recurrent cerebral ischemic events in the long-term follow up after intracardiac echocardiography (ICE)-aided PFO closure in a large population.

Methods: We reviewed the medical and instrumental data of 1,000 consecutive patients (mean age 47.
