Product Details

Left atrial appendage closure (LAAC) with WATCHMAN™ is a proven one-time procedure that reduces the risk of stroke in your non-valvular atrial fibrillation (NVAF) patients and the risk of bleeding that comes with a longterm oral anticoagulant use. 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.2 Following the procedure, physicians may prescribe an individual post-implant medication considering patient preference, stroke and bleeding risk. Treatment options may include a dual antiplatelet therapy (DAPT) or an oral anticoagulation therapy with warfarin or NOAC (non-Vitamin-K oral anticoagulation) along with ASS for at least three months.
