The AtriClip devices are epicardially applied to the base of the left atrial appendage (LAA) during cardiac surgery procedures such that the LAA is permanently excluded from the left atrium of the heart. This exclusion eliminates communication of blood between the left atrium (LA) and the LAA and results in the electrical isolation of the LAA from the rest of the heart.1-4 The AtriClip devices are available on a variety of delivery systems optimized for open concomitant procedures as well as minimally invasive surgery, both through a thoracotomy and a port.
In peer reviewed science, AtriClip devices achieved an average exclusion success rate of more than 97% with success criteria of no residual flow between the LAA and LA and a residual LAA neck of ≤ 1.0 cm5-16. In these studies, there were no device migrations and no device related complications with more than 5 years of follow-up.
The AtriClip devices’ extraordinary performance may be due to its unique attributes:
