Bridge or Continue Coumadin for Device Surgery Randomized Controlled Trial

Summary

Many cardiac patients requiring device (defibrillator or pacemaker) related surgery are on chronic oral anticoagulation therapy (usually coumadin). The risk of blood clot formation related to stopping oral anti-coagulant therapy is currently managed by using bridging heparin therapy in patients with moderate to high risk of blood clot formation. There is a substantial risk of bleeding in the pocket where the device is situated (pocket hematoma)related to bridging therapy. The purpose of this study is to compare the current standard of care of bridging with heparin to an experimental strategy of continuing coumadin therapy in higher risk patients undergoing device surgery, with the hypothesis being that the continued oral anti-coagulation group will have a lower pocket hematoma rate as compared to the bridging with heparin group.
