“…Appropriate sizing requires the device to be approximately 10–20% larger than the LAA 35. To implant the Watchman device, a specialized 12-F access sheath is used to enter the LAA and serves as a duct for the delivery catheter.…”

“…Appropriate sizing requires the device to be approximately 10–20% larger than the LAA. 35 To implant the Watchman device, a specialized 12-F access sheath is used to enter the LAA and serves as a duct for the delivery catheter. After access is obtained under TEE and fluoroscopy guidance, a pigtail catheter is advanced into the LAA, and the sheath is then advanced over the pigtail into the LAA.…”

Atrial fibrillation (AF) increases the risk for thromboembolic stroke five-fold. The left atrial appendage (LAA) has been shown to be the main source of thrombus formation in the majority of strokes associated with AF. Oral anticoagulation with warfarin and novel anticoagulants remains the standard of care; however, it has several limitations, including bleeding and poor compliance. Occlusion of the LAA has been shown to be an alternative therapeutic approach to drug therapy. The purpose of this article is to review the different techniques and devices that have emerged for the purpose of occluding this structure, with a particular emphasis on the efficacy and safety studies published to date in the medical literature.
