Abstract

Objectives: Left atrial appendage (LAA) plays a crucial role in the etiopathogenesis and prevention of stroke during nonvalvular atrial fibrillation (AF). We present our results with an external occlusion system (AtriClip, AtriCure, West Chester, OH)

 Group of patients, method: We performed 233 occlusion of LAA by AtriClip from 9/2012 till 9/2017, 1 year follow up was in 155 pts - 3094 pts/months. We implanted AtriClip from sternotomy/thoracotomy/minithoracotomy in 77 pts and thoracoscopicly in 78 pts. Follow up was clinical/phone control and TTE/TEE or CT before dimision and 1 year after implantation. We focused on bleeding/thrombembolic events and stability of system (residual leak, residual stump more that 1 cm)

 Results: During hospitalisation and follow up we recorded 4 transitory ischemic attack (TIA) and 2 cerebrovascular accident (CVA). On ultrasound or CT we founded only 2 times neck more than 1 cm (no clinical consequention) and no any endoleak.

Conclusion: Using of occlusion system AtriClip seems to be very effective and reproducible  metod for occlusion of LAA with very low risk of complication. Probably it is the most effective and safe metod for occlusion of LAA
