Percutaneous left atrial appendage occlusion in patients with non-valvular atrial fibrillation: implantation and up to four years follow-up of the AMPLATZER Cardiac Plug.

Abstract

LAAO is a safe and effective stroke prevention therapy in a high-risk NVAF cohort, both at implantation and over longer follow-up periods. The long-term assessed ischaemic stroke rate in patients treated with LAAO is markedly reduced compared to the expected rate based on the patients' risk scores.
