• Atrial fibrillation or A-fib is a common cardiac disease that occurs as individuals get older.
• A risk factor of atrial fibrillation is blood clot formation and dislodgement or ‘embolus’ in the left atrium.
• Current treatment methods to prevent clot formation include anticoagulants, as well as a left atrial appendage closure device, The Watchman’s device is the only FDA approved left atrial appendage closure device.
• Study results confirm the rising efficacy and cost effectiveness of Watchman’s device versus long term anticoagulant therapy as well as their adverse effects regarding placement and post procedure; however further randomized control trials are needed to compare both therapies particularly novel oral anticoagulants head to head rather than through extrapolation.
• Long term effects of Watchman’s device need to be studied.
