WATCHMAN FLX LAAC Procedure

1

Using a standard percutaneous technique, a guidewire and vessel dilator are inserted into the femoral vein.

2

The implant procedure is performed with fluoroscopy and transesophageal echocardiography (TEE). The interatrial septum is crossed using a standard transseptal access system.

3

The access sheath is advanced over the guidewire into the left atrium and then navigated into the distal portion of the LAA over a pigtail catheter.

4

WATCHMAN FLX is then deployed and released in the LAA.

5

Heart tissue grows over the WATCHMAN FLX Implant and the LAA is permanently sealed.

Post-Implant Drug Regimen

Post-implant medication is at the the discretion of each physician and is subject to the patient's specific condition and medical history. Boston Scientific does provide general guidelines in the instructions for use (IFU) of the device, based on the robust clinical results observed in the RCTs and the EWOLUTION registry.
