Summary

The objective of Left atrial appendage closure compared to standard antiplatelet therapy in patients with AF who underwent percutaneous coronary intervention (LLA-PCI) study is to evaluate the safety and efficacy of implantation of left atrial appendage closure compared to standard antiplatelet therapy for prevention of thromboembolic events and stent thrombosis in subjects with AF who underwent PCI.

DEVICE

Left Atrial Appendage Closure Device (Watchman)

This device is a self-expanding nickel titanium (nitinol) frame structure with fixation barbs and a permeable polyester fabric cover. The device ranges in diameter from 21 mm to 33 mm to accommodate varying LAA anatomy and size. It will be implanted via a trans-septal approach by use of a catheter based delivery system to seal the ostium of the LAA. The implantation will be guided by fluoroscopy and TEE to verify proper positioning and stability. The dose of warfarin will be adjusted to maintain INR 2.0 - 3.0 for 45 days. If TEE data shows no additional flow in LAA, warfarin will be discontinued: Aspirin dose: 75 mg for all period of study; Clopidogrel dose: 75 mg for 6 months after procedure.

DRUG

Warfarin

Warfarin dose adjusted to maintain INR 2.0-3.0 for all period of study; Aspirin dose-75mg for 45 days after randomization; Clopidogrel dose-75mg for 6 months after procedure. All drugs will be started before PCI procedure. Low molecular weight heparins will be used before procedure and will be stopped when INR reach 1.8-2.0.
