Abstract
INTRODUCTION: Totally thoracoscopic ablation for symptomatic atrial fibrillation (AF) refractory to drug or catheter based therapy is indicated as a Class 2A recommendation according to latest guidelines. Evidence for long-term rhythm control and stroke reduction is limited. The aim of this study was to report on long-term outcome after totally thoracoscopic ablation. METHODS AND RESULTS: In total 82 consecutive patients were included that underwent totally thoracoscopic ablation including left appendage closure (2012-2013). The primary outcome was freedom from atrial arrhythmia recurrence. Secondary outcomes were survival, freedom from cerebrovascular events, freedom from reablation and definite pacemaker implantation. The mean age was 59.9 ± 8.6 years and 71% were male. The mean CHA2 DS2 -VASc score was 1.2 ± 1.0. The overall freedom from atrial arrhythmia was 60% after a mean follow up of 4.0 ± 0.6 years. Freedom from cerebrovascular events was 98.8% after mean follow-up of 4.4 ± 0.3 years and overall survival was 98.8%, with one noncardiac related death. The observed rate of ischemic stroke, hemorrhagic stroke or transient ischemic attack was 0.3 per 100 patient-years. CONCLUSIONS: Totally thoracoscopic ablation is an effective sustainable rhythm control therapy for AF with a reasonable recurrence rate and low stroke rate when performed in dedicated AF centers.
