2018 AF Symposium Live Case: Installing a Coherex WaveCrest LAA Occlusion Device

by Steve S. Ryan, PhD.
Background: The Coherex WaveCrest Left Atrial Appendage (LAA) occlusion device is not yet approved by the FDA for use in the U.S. The WaveCrest is similar in purpose to the Boston Scientific Watchman™ LAA Closure Device (which is FDA approved).

Tom De Potter MD

Dr. Tom De Potter of Aalst, Belgium, presented a live case in which he installed a Coherex WaveCrest Left Atrial Appendage (LAA) occlusion device in an 84-year-old female with longstanding A-Fib and a bleeding problem.

The WaveCrest has roll-out anchors which are then fixed into the sides of the LAA. It comes in three sizes to fit different LAA openings.Live Streaming Video from AF Symposium at

He spent a good deal of time and attention washing and immersing the WaveCrest in water to make sure there were no bubbles.

When the device is expanded inside the LAA, it can be repositioned and recaptured. Dr. Potter seemed to tug and firmly push and pull the device to anchor it.  After insertion, it requires 2 months of dual antiplatelet therapy.

WaveCrest is from Coherex Medical, Inc., a subsidiary of Biosense Webster/Johnson & Johnson.

Video animation is available: The Coherex Medical website has a short (35-second) showing the installation of the Coherex WaveCrest Left Atrial Appendage (LAA) occlusion device. Go to video on the Coherex website->

Editor’s Comments:
To me the WaveCrest seemed similar to Boston Scientific Watchman LAA Closure Device which did all the heavy lifting to be the first LAA occlusion device to get U.S. FDA approval.
I didn’t see major significant advantages of the WaveCrest. Though it’s always good for EPs to have a choice of devices when closing off the LAA.
For more on the Watchman, see  my article, The Watchman™ Device: An Alternative to Blood Thinners.
