Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Edoxaban Arm
All patients enrolled in the study will receive 6 weeks of edoxaban therapy, at which time a TEE will be performed. If the result is acceptable, edoxaban will be discontinued, and the patient will be treated with dual antiplatelet therapy (aspirin and clopidogrel) until 6 month follow-up. If device thrombus is present at 6 week TEE, patient will be transitioned to aspirin and adjusted-dose warfarin and LAA reassessed by TEE in 6 weeks; further warfarin will be continued according to operator preference. Subjects will have a 6 month follow-up visit prior to study completion. After study completion, patients may be treated with aspirin monotherapy according to the FDA instructions for use for the WATCHMAN device, or according to operator discretion.
Edoxaban
Edoxaban 60mg once daily in patients with CrCl \>50- ≤95 mL/min, or 30mg once daily in patients with CrCL 15-50 mL/min.
If at 6 week TEE LAA closure is deemed acceptable by the operator (i.e., peri-device flow \<5mm), edoxaban will be discontinued. Aspirin 81mg daily and clopidogrel 75mg daily will be administered until 6-month follow-up, then clopidogrel will be discontinued.
If LAA unacceptable on 6-week TEE due to peri-device flow ≥5mm, edoxaban will be continued for an additional 6 weeks, and LAA reassessed by TEE If device thrombus is present at 6-week TEE, patient will be transitioned to aspirin 81 mg daily and adjusted-dose warfarin (goal INR, 2.0-3.0), and LAA reassessed by TEE in 6 weeks; further warfarin will be continued according to operator preference.
WATCHMAN LAA Closure
Per Inclusion Criteria, enrolled subjects must have a successful Left Atrial Appendage (LAA) Closure using the WATCHMAN Device
Aspirin and Clopidogrel
If at 6 week TEE LAA closure is deemed acceptable by the operator edoxaban will be discontinued, and aspirin 81mg daily and clopidogrel 75mg daily will be administered until 6-month follow-up. Then clopidogrel will be discontinued.
Aspirin 325mg daily rather than 81mg daily can be administered according to operator preference after the 6-week follow-up visit.
Aspirin and Warfarin
If device thrombus is present at 6-week TEE, patient will be transitioned to aspirin 81 mg daily and adjusted-dose warfarin (goal INR, 2.0-3.0), and LAA reassessed by TEE in 6 weeks; further warfarin will be continued according to operator preference.

Edoxaban
Edoxaban 60mg once daily in patients with CrCl \>50- ≤95 mL/min, or 30mg once daily in patients with CrCL 15-50 mL/min.
If at 6 week TEE LAA closure is deemed acceptable by the operator (i.e., peri-device flow \<5mm), edoxaban will be discontinued. Aspirin 81mg daily and clopidogrel 75mg daily will be administered until 6-month follow-up, then clopidogrel will be discontinued.
If LAA unacceptable on 6-week TEE due to peri-device flow ≥5mm, edoxaban will be continued for an additional 6 weeks, and LAA reassessed by TEE If device thrombus is present at 6-week TEE, patient will be transitioned to aspirin 81 mg daily and adjusted-dose warfarin (goal INR, 2.0-3.0), and LAA reassessed by TEE in 6 weeks; further warfarin will be continued according to operator preference.
WATCHMAN LAA Closure
Per Inclusion Criteria, enrolled subjects must have a successful Left Atrial Appendage (LAA) Closure using the WATCHMAN Device
Aspirin and Clopidogrel
If at 6 week TEE LAA closure is deemed acceptable by the operator edoxaban will be discontinued, and aspirin 81mg daily and clopidogrel 75mg daily will be administered until 6-month follow-up. Then clopidogrel will be discontinued.
Aspirin 325mg daily rather than 81mg daily can be administered according to operator preference after the 6-week follow-up visit.
Aspirin and Warfarin
If device thrombus is present at 6-week TEE, patient will be transitioned to aspirin 81 mg daily and adjusted-dose warfarin (goal INR, 2.0-3.0), and LAA reassessed by TEE in 6 weeks; further warfarin will be continued according to operator preference.
