↵∗ In these 7 cases, the devices were deployed but not released as they did not meet the device release criteria, which include the following: 1) the implant is positioned at or slightly distal to and spans the entire left atrial appendage ostium; 2) the implant is stable (by gentle tug test); 3) the implant size is appropriate once deployed; and 4) the implant seals off the left atrial appendage from the left atrium (jet around the device <5 mm) and all lobes are distal to implant.
