Removing or Closing Off the Left Atrial Appendage
For more recent articles, see The Role of the Left Atrial Appendage (LAA) & Removal Issues and Left Atrial Appendage May be Important for Heart Repair
Removing or closing off the Left Atrial Appendage (LAA) may affect how well the heart pumps and is of special concern to athletes and to those with heart pumping problems. In canine studies the LAA provided 17.2% of the whole left atrial volume of blood pumped. It’s possible that removing or closing off the LAA may lead to heart pumping problems and exercise intolerance.
Though still in clinical trials, the Watchman Device is available for most people. For a list of US doctors installing the Watchman Device, go to Doctors Installing the Watchman Device. (Posted 2011)
