Pharmacologic agents evaluated include warfarin, aspirin, other anti platelets agents, direct thrombi inhibitors and antiarrhythmic drugs. Nonpharmacologic treatments reviewed include surgical and catheter ablation, pacing, left atrial appendage ligation and occlusion methods, and atrial defibrillators.
