Watchman Procedure

The multidisciplinary Watchman™ Left Atrial Appendage Closure (LAAC) team at the CHI Health Heart Institute has extensive experience in procedural treatment of cardiovascular arrhythmias. The LAAC team is part of the Structural Heart Clinic and has been trained to implant the FDA-approved Watchman™ device. In addition, the CHI Health Heart Institute is a select site for clinical research, offering the latest in device technology through access to clinical trials.

The Watchman™ Left Atrial Appendage (LAA) Closure Technology is a minimally invasive, advanced therapy used to treat some patients living with Atrial Fibrillation (AF) who are at increased risk for stroke. Patients who are implanted with a Watchman device are followed through the Arrhythmia Clinic at the CHI Health Heart Institute.

Watchman is an umbrella-like device that is placed using a catheter. It is the only FDA-approved LAA closure device that effectively reduces stroke risk from thromboembolism from the left atrial appendage in patients with atrial fibrillation.
