Left Atrial Appendage Occlusion Devices for Stroke Prevention in Atrial Fibrillation

The WATCHMAN Implant offers a groundbreaking alternative to blood thinners for reducing stroke risk in people with non-valvular atrial fibrillation. Find out who is, and who isn’t, a candidate for WATCHMAN.

Rather than removing the Left Atrial Appendage (LAA) surgically, the LARIAT procedure closes it off non-surgically, using a loop of suture material. Catheters are used to deliver the suture loop, slip it around the LAA, and tighten it to close off the LAA. This isolates the LAA, potentially reducing its ability to add to the irregular rhythm of the heart. The scar that forms as the area around the suture heals simulates the scars created in non-surgical and surgical maze procedures.

If you have persistent Afib (atrial fibrillation), you may benefit from participating in a medical research study for patients diagnosed with persistent or longstanding persistent Afib. The study is called the aMAZE Trial: Left Atrial Appendage Ligation with the LARIAT Suture Delivery System as Adjunctive Therapy to Pulmonary Vein Isolation (PVI) for Persistent or Longstanding Persistent Atrial Fibrillation.
