NCT02022527

Brief Summary

The combined Antiplatelet and Anticoagulant treatment decreased thrombus formation and overall mortality. Also the initiation of an efficacious early anticoagulation protocol is important because of its potential impact on the rate of early thromboembolic complications after mechanical valve implantation. An important question that remains to be answered is whether the combination would be cost effective than Warfarin alone, with a reduction in major bleeding. In addition, the knowledge about its cost-effectiveness has not yet been established in Egypt. The aim of this trial based economic evaluation is to conduct a cost-effectiveness analysis for combination of low-dose Aspirin and Warfarin versus Warfarin alone in prosthetic valve patients from the medical provider perspective specially that a misconception is still existed between the physicians in Egypt that the cost of complications is not worthy so our main aim is to test the cost of complications.
