WATCHMAN™ Implant Procedure


The WATCHMAN™ LAA Closure Device placement procedure may be done under local or general anaesthesia in a catherisation laboratory setting using a standard transseptal technique. The procedure usually lasts about an hour and the patient is typically in the hospital for 24 hours following the procedure.

A transoesophageal echocardiogram (TOE) is performed to measure the LAA to determine which size WATCHMAN™ Device to be implanted. After the inter- atrial septum is crossed using a standard transseptal access system, the WATCHMAN™ Access Sheath and Dilator are advanced over a guidewire into the left atrium. The Access Sheath is then carefully advanced into the distal portion of the LAA over a pigtail catheter. The WATCHMAN™ Delivery System is prepped, inserted into the Access Sheath, and slowly advanced under fluoroscopic guidance. The WATCHMAN™ Device is then deployed into the LAA. The device release criteria are confirmed via fluoroscopy and prior to releasing the Device.

What happens after the WATCHMAN™ device is implanted?

It takes at least 45 days for the heart tissue to heal. During that time, it’s important to continue taking blood thinning medication (Warfarin) and a daily Aspirin. At 45 days, a repeat transoesophageal echo will be performed to check the WATCHMAN™ device. At this time blood thinning medication may be discontinued and Plavix® or clopidogrel is prescribed.

What are the risks of the WATCHMAN™ LAA Closure Device?

Clinical studies show that the WATCHMAN™ device can be safely implanted. However, like for any procedure, there are risks associated with the implantation of the WATCHMAN™ device. These risks will be explained by the implanting physician.

Who can benefit?

Patients who have non-valvular atrial fibrillation who require treatment for potential blood clot formation and can take anticoagulation medication such as Warfarin may be eligible to be treated with the WATCHMAN™ device.

Do you have atrial fibrillation that requires you to be on anticoagulant therapy?

If so, you may be eligible for treatment with the WATCHMAN™ device that may replace your need for long term anticoagulant therapy. Ask your doctor if you are a candidate for this treatment.
