Timely discontinuation of NOAC's therapy before surgery is not always achievable, especially in an emergency setting. This case report proves, with direct blood concentration measurements, the efficacy of CytoSorb hemofilter in apixaban removal during cardiopulmonary bypass for emergency aortic valve replacement.
Abstract
What is known and objective
Emergent cardiac surgery in patients under anticoagulant therapy is still a major point of concern. Recently approved reversal agents are often not available or not suitable in the cardiac surgery setting, and timely discontinuation of the drug is not always feasible. CytoSorb® haemoadsorption therapy has been approved in Europe for intraoperative ticagrelor and rivaroxaban removal during cardiopulmonary bypass (CPB), but thus far the efficacy of CytoSorb® haemoadsorber on other anticoagulants (apixaban, dabigatran, edoxaban) has only been tested in vitro, and some signals of clinical benefits have reported in a few case reports.
Case summary
We describe a case of CPB implementation with CytoSorb® in a haemodynamic unstable patient with prosthetic aortic valve endocarditis on apixaban therapy.
What is new and conclusion
CytoSorb® proved to be effective for removal of apixaban in emergency surgery setting by direct measurements of drug levels before and during CPB circulation.
