Abstract
Methods for closing a left atrial appendage rely on introducing a closure tool from a location beneath the rib cage, over an epicardial surface, and to the exterior of the left atrial appendage. The closure device may then be used to close the left atrial appendage, preferably at its base, by any one of a variety of techniques. One specific technique uses graspers and a closing loop. Methods may include advancing a closure tool adjacent to the left atrial appendage using a sub-xiphoid approach and closing the left atrial appendage using the closure tool. Methods may also include advancing a loop adjacent to the left atrial appendage using a sub-xiphoid approach and closing the left atrial appendage using the loop.
