When LMWH or UFH bridging is used for an invasive procedure, we suggest that such therapy be restarted after the procedure when hemostasis is established (usually 24 hours for a procedure with a low risk of bleeding and 48-72 hours for a procedure with an intermediate or high risk of bleeding) in prophylactic dosages for the first 24 to 72 hours and then increased to therapeutic dosages. Bridging is then continued until an OAC is therapeutic (Conditional Recommendation, Low Quality Evidence)
