Systemic anticoagulation is recommended to prevent thrombosis. Unfractionated heparin (UFH) and direct thrombin inhibitors (DTIs) are anticoagulant agents that inactivate thrombin; however, UFH requires antithrombin III (ATIII) for its activity, and patients supported by ECMO are at risk for acquired ATIII deficiency. In addition, heparin may cause heparin-induced thrombocytopenia, complicating therapy. Guidelines on anticoagulant use in ECMO reference UFH as a recommended agent with DTIs as an alternative option. Meta-analyses comparing the 2 agents in ECMO have evaluated efficacy and safety; however, discordant results prompt the need for additional research.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Objective:<\/jats:title>\n                    <jats:p>The objective of this study is to evaluate differences in bleeding and thrombotic events between UFH and bivalirudin for anticoagulation during ECMO support.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods:<\/jats:title>\n                    <jats:p>This study is a retrospective, single-center cohort study conducted at a primary ECMO center and a tertiary academic medical center.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Bleeding and systemic thrombosis rates were not different between bivalirudin and UFH (30 vs 33 events, hazard ratio [HR] = 0.89; 95% confidence interval [CI] = 0.55-1.47,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.7; 12 vs 17 events, HR = 0.68; 95% CI = 0.32-1.42,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.3); however, when controlled for covariates, device thrombosis was lower with bivalirudin (30.2% vs 43.4%,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.017).
