Anticoagulant management during percutaneous coronary intervention for a patient with antithrombin deficiency

Abstract

Previous reports on cardiac intervention in cases with antithrombin deficiency are extremely limited. We report a case of acute coronary syndrome with antithrombin deficiency in a 62-year-old man with multiple histories of thrombosis. He had worsening chest pain, and laboratory data showed an elevated level of troponin T, suggesting acute myocardial infarction. Currently, there is no fixed anticoagulation strategy for coronary intervention in patients with antithrombin deficiency. In this case, we performed coronary intervention with heparin in addition to antithrombin concentrate. The intervention was successfully performed without thrombosis or bleeding complications.

Learning objective: Antithrombin deficiency is a rare disorder and data about coronary intervention for cases with antithrombin deficiency are limited. We successfully performed intervention with our anticoagulant management and it would be beneficial for future reference.
