Left Atrial Appendage Management

The AtriClip device is placed at the base of the left atrial appendage (LAA) excluding it from the left atrium resulting in the electrical isolation of the LAA.1-4 In peer-reviewed publications the AtriClip device achieved a successful LAA exclusion rate in 97% on average. LAA exclusion success is defined as no residual flow between the LAA and left atrium, and a residual LAA neck ≤ 1.0 cm in length.5-15
