Extracorporeal membrane oxygenation with hemoconcentration: in a hypervolemic patient with critical aortic stenosis.

Herein, we describe the case of a 60-year-old man with severe nonischemic cardiomyopathy and hypervolemia. By means of venoarterial extracorporeal membrane oxygenation at the bedside, along with hemoconcentration, the patient was resuscitated from severe cardiogenic shock and normal blood volume was restored. Within 24 hours, he was able to undergo a high-risk aortic valve replacement for severe aortic stenosis, with a successful outcome. To our knowledge, this is the first reported case in which hemoconcentration with extracorporeal membrane oxygenation has been used to support a patient with severe hypervolemia.
