Abstract 11766: Long Term Follow-up and Outcome of Atrial Fibrillation Patients With Left Atrial Appendage Obliteration Using Wireless Absorbable Occluders

Introduction: Metal occluders for the left atrial appendage (LAA) have been associated with morbidity that prevents their use as a primary approach for stroke prevention, in the majority of patients with atrial fibrillation(AF). Information on their long term outcome is limited. We hypothesize that a safe and effective occluder that reduces this morbidity with good long term outcome, could potentially replace anticoagulation in all patients with AF. Methods: The Transcatheter Patch (TP) is an absorbable wireless device made by inflatable polyurethane. It was successfully implanted in the LAA for stroke prevention in 27/30 high risk for stroke patients (CHADS2 score>3) from 2005-2012. The patient age varied from 28-89 years and the LAA mouth diameter from 12-24 mm. No patient received supplemental anticoagulation. The patients were followed by transesophageal echocardiography (TEE) at 1 month, 6 months and one year. They had yearly clinical follow-ups, thereafter. The results along with the clinical outcom...
