Abstract:
Percutaneous left atrial appendage (LAA) occlusion is commonly performed using umbrella-shaped devices. However, the utility of such devices is highly dependent on the underlying anatomy of the appendage. For the first time, we report the use of an Occlutech PFO closure device to successfully occlude a left atrial appendage that possessed a circumferential ridge at its mouth. PFO closure devices would also be suitable for the occlusion of left atrial appendages when an incomplete surgical closure results in a circumferential ridge.
