What are the risks associated with the WATCHMAN LAA Closure Device?
The WATCHMAN LAA Closure Device has been found to have a serious complication rate of around 7%, including pericardial effusions requiring drainage, procedure-related ischemic stroke, and increased risk of bleeding due to the need for DAPT for at least 6 weeks after the procedure. Inexperienced operators may also lead to incomplete occlusion of the LAA after LARIAT ligation, which is associated with additional risk.
