The WATCHMAN LAA Closure Technology is intended to prevent thrombus embolization from the left atrial appendage and reduce the risk of life-threatening bleeding events in patients with non-valvular atrial fibrillation who are eligible for anticoagulation therapy or who have a contraindication to anticoagulation therapy.1
The ESC guidelines recommend to assess the stroke and bleeding risks in the decision-making process for thromboprophylaxis in patients with non-valvular AF by using respectively the CHA2DS2-VASc and HAS-BLED scores.
“Decision-making for thromboprophylaxis needs to balance the risk of stroke against the risk of major bleeding, especially ICH, which is the most feared complication of anticoagulation therapy and confers a high risk of death and disability” (ESC guidelines 2012)
CHA2DS2-VASc is a risk assessment system developed by Lip et. Al., which refines the older CHADS2 score by including additional stroke risk factors and putting greater emphasis on age as a risk factor.2,3

HAS-BLED score was developed as a practical risk score to estimate the 1-year risk for major bleeding in patients with AF.4

The Boston Scientific Stroke-Bleed Risks Calculator will help you easily balance the risk of stroke against the risk of bleeding prior to decide the best treatment option for your AF patients; and consider the LAAC therapy for your AF patients who are at high risk of stroke & bleeding.

The WATCHMAN™ LAAC Device offers patients with atrial fibrillation a life-changing treatment option which can free them from the burden of long-term warfarin therapy.
The WATCHMAN Device has been implanted in thousands of patients around the world. Here you can watch the testimonials of individuals as they describe their personal experiences, both before and after treatment.

These stories reflect the experience of individuals with a WATCHMAN Left Atrial Appendage Closure Device. Boston Scientific invited these people to share their stories candidly. Please bear in mind that the experiences are specific to these particular individuals. Not everyone who receives left atrial appendage closure therapy will receive the same results as the individuals in these stories.
