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 blood flow and electrical 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
In a published meta-analysis of over 900 clip placements, the authors observed there were no device migrations and no device related complications with more than five years follow-up.
A human clinical study found that within minutes of the epicardial application of the AtriClip Device, the LAA becomes electrically isolated from the left atrium and ischemic injury results in the cessation of electrical activity in the LAA.2 Postoperatively, the excluded and necrosed LAA is resorbed and no longer a factor in the propagation of electrical activity.3,4,6
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.
