Abstract:
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.

Critical Region, Critical Values and Significance Level
In hypothesis testing, a sample statistic is converted to a test statistic using z, t, or chi-square distribution. A critical region is an area under the curve in probability distributions demarcated by the critical value. When the test statistic falls in this region, it suggests that the null hypothesis must be rejected. As this region contains all those values of the...
