Emergency cardiac surgery for patients on NOACs in the NOAC era - Perspective.

ABSTRACT

Excessive bleeding is an important cause of morbidity and mortality after cardiac surgery. Bleeding after cardiac surgery is multifactorial. Adherence to the proverbial 6 Ps remains the cornerstone of any strategy for management of postoperative bleeding after cardiac surgery. Recent years have seen a surge in the number of patients who have been prescribed novel oral anticoagulants (NOACs) for the prevention and treatment of thromboembolic events. This phenomenon has significant repercussions particularly for patients presenting for emergency cardiac surgery. The published evidence guiding management of such patients is limited and in the form of expert consensus. Plasma levels of NOAC >30 ng/ml necessitate specific therapeutic interventions to tackle excessive bleeding attributed to NOAC intake. Current recommendation is to consider using specific reversal agent if available. Otherwise, use of prothrombin complex concentrates is recommended.
