Perioperative Applications of Therapeutic Plasma Exchange in Cardiac Surgery: A Narrative Review.

Therapeutic plasma exchange (TPE) has a number of applications in cardiac surgical patients and has been used increasingly in high-risk heart and lung transplant patients. In this narrative review, the authors describe TPE principles, complications, and specific indications for TPE, including thrombotic thrombocytopenic purpura, heparin-induced thrombocytopenia, induction of immunotolerance in heart and lung transplant patients, and treatment of antibody-mediated rejection in heart and lung transplant patients. The review is based on published literature and the authors' institutional experience with perioperative TPE in cardiac surgical patients.
