Objective To retrieve the anticoagulation management related evidences in postoperative patients with heart valve operation to provide an evidence-based basis for medical professionals conducting the antithrombotic therapy in postoperative patients with heart valve operation.Methods The related evidences of anticoagulation management after heart valve surgery were retrieved from major databases and websites at home and abroad based on the"6S"evidence resource pyramid modeling system.The retrieval time was from January 1,2017 to February 29,2024.Two researchers trained by evidence-based care evaluated the quality of the literatures and extracted the relevant evidences meeting the criteria by combining with clinical situation.Results A total of 12 literatures were included,including 5 guidelines,4 clinical practices and 3 expert consen-sus.Thirty pieces of best evidences were summarized in eight aspects:contraindications,postoperative an-tithrombotic regimens,warfarin use method,vitamin K use precautions,daily life precautions,anticoagulation complications,long term perioperative anticoagulation bridging and complicating pregnancy.Conclusion The evidences summarized in this study could provide a reference for standardizing anticoagulation management in postoperative pa-tients with heart valve operation and for clinical healthcare workers in order to standardize the anticoagulation therapy after heart valve replacement and reduce the occurrence of anticoagulation-related complications.
