Abstract
Background and Aim Cardiopulmonary bypass (CPB) in antiphospholipid syndrome (APS) patients carries a high risk of thrombosis and hemorrhage. However, optimal anticoagulation surveillance methods have not been established and heparin optimization has not yet been totally validated as reflective of anticoagulation status. Methods and Result Here, a 45‐year‐old female with APS underwent mitral valvuloplasty due to infective endocarditis. We used a perioperative, in vitro, heparin‐activated clotting time (ACT) titration line coupled with synergistic, intraoperative thromboelastography (TEG) to monitor coagulation activity. After the ACT target was reached, TEG monitored the suppression of both intrinsic and extrinsic coagulation activity throughout the surgery. Conclusion TEG thus provided valuable temporal information on both intrinsic and extrinsic coagulation suppression validating heparin‐ACT titration targets.Keywords
