Watchman Left Atrial Appendage Closure (LAAC) Device placement in New Jersey | Hackensack Meridian Health   


What is the Watchman™ Procedure?

WATCHMAN™ Left Atrial Appendage Closure (LAAC) Device placement is a first-of-its-kind, proven alternative to long-term Warfarin (blood thinner) therapy to reduce the risk of stroke in patients with non-valvular atrial fibrillation (AFib).  The WATCHMAN™ can help free patients from a lifetime of blood thinner medication. In fact, long-term follow-up studies of patients who underwent this ground-breaking procedure showed the WATCHMAN™ device implantation offered a similar stroke risk reduction and superior reductions of hemorrhagic stroke, disabling stroke and cardiovascular death compared to the blood-thinning medicine warfarin. Nearly all patients in the study were completely off Warfarin within a year.

Who is a Candidate for the Watchman™ Procedure? 

Watchman™ is suitable only for people with an AFib diagnosis that isn’t caused by a heart valve problem. 

What To Expect During the Watchman™ Procedure

The WATCHMAN™ is a tiny umbrella-shaped device that an interventional cardiologist or cardiac electrophysiologist permanently implants in the atrium of the heart. Using a catheter (similar to an IV) that enters the groin, the cardiologist threads it up into the heart and sets the Watchman in place so it permanently seals the opening of the atrium. The heart eventually covers it permanently with new tissue so there is no longer any place for a clot to form.

Patients receive general anesthesia during the hour-long procedure. Most patients stay in the hospital overnight for observation and return home the next day. Although full recovery time varies, patients generally return to normal life activities within a week.
