In this article I will discuss the watchman procedure for patients with atrial fibrillation, and discuss who would be ideal an candidates for this procedure. It is something that is in the background and will be seen with the devices we know, including the Watchman device. It is possible that the LAA could rupture while the device is deployed. The procedure takes about an hour. Long-term Warfarin therapy is not appropriate for every patient. The Watchman occluder is a device for percutaneous LAA occlusion and is at present investigated in the PROTECT AF trial. 9 The delivery mechanism has three components: the Watchman device, the delivery catheter,and a transseptal access sheath. In the PREVAIL trial, the rate of major complications, such as major bleeding around the heart requiring urgent surgery, dislodgment of the watchman device, and procedure related strokes were all less then 1%. The WATCHMAN device is a one-time, permanent implant that reduces the risk of stroke in patients with AFib, eliminating the need for and long-term risk of bleeding caused by blood thinners such as warfarin. The WATCHMAN Left Atrial Appendage Closure Device is implanted at the opening of the left atrial appendage and is intended to prevent left atrial appendage blood clots from entering your blood stream and potentially causing a stroke. The WATCHMAN Device is a parachute-shaped, self-expanding device that closes the LAA. The implant is designed to For some patients this therapy carries a significant risk for bleeding complications. The Watchman device has provided favorable outcomes as well as improvements on complications that confounded other same-type devices. Since its FDA approval in March 2015, the Watchman™ left atrial appendage closure device has been implanted into nearly 50,000 patients with nonvalvular atrial fibrillation (AF) as a nonpharmacologic alternative for reducing stroke risk. The device is implanted in the left atrial appendage in order to block the main source of thrombi in atrial fibrillation. The WATCHMAN™ Device is permanently implanted at or slightly distal to the ostium (opening) of the LAA, which is known to be the source of more than 90% of stroke-causing bloods clots in people with non-valvular AF. The yellow arrow shows device face in landing zone of LAA. It was tested in several studies that showed the device was a good alternative treatment for patients who cannot tolerate treatment with warfarin. Left atrial appendage occlusion (LAAO), also referred to as Left atrial appendage closure (LAAC) is a treatment strategy to reduce the risk of left atrial appendage blood clots from entering the bloodstream and causing a stroke in patients with non-valvular atrial fibrillation (AF).. with WATCHMAN . WATCHMAN COMPLICATIONS REPORTED IN THE MANUFACTURER AND USER FACILITY DEVICE EXPERIENCE DATABASE. It is done to reduce the risk of stroke in people with non-valvular atrial fibrillation (Afib) and is an alternative to long term blood thinners. In (A), the LAA shows anterior chicken wing anatomy, pigtail catheter advanced through WATCHMAN™ access sheath in the appendage, contrast filling anatomy of the appendage. Looking only at the Watchman device, there was an increase in the rates of various complications from the preapproval to the postmarketing period, characterized by an initial large increase followed by declining rates. In view of this, we will be hearing more about the Watchman and other LAA-occlusion devices in the future. Use of the Watchman left atrial appendage closure (LAAC) device has been linked to high rates of success among cardiac patients with atrial non-valvular atrial fibrillation (AF), according to research 1 presented at the 2016 Transcatheter Cardiovascluar Theraputics (TCT) scientific symposium in Washington, DC.. Data were simultaneously published online in the Journal of the American College … It was tested in several studies that showed the device was a good alternative treatment for patients who cannot tolerate treatment with warfarin. Furthermore, it was associated with a low number of periprocedural complications, and provided outstanding device sealing at follow-up, with no cases of device embolization and a similar rate of device-related thrombosis compared to previous studies. At Cleveland Clinic, we have performed more than 200 of those procedures, with excellent results.
