Very Low Dose Oral Anticoagulation and Thromboembolic and Bleeding Complications

Summary

We aim to investiagte whether very low dose self management of oral anticoagulation is superior to low dose oral anticoagulation in order to prevent bleeding events in patients undergoing mechanuical heart valve replacement.
