2. Fig 1
Coronary flow evaluation. The flow decreases in C1 and C4 when compared with C1 and C3 (p = ). (C1 = Control; C2 = Biopump test; C3 = Biopump and intraaortic balloon pump test; C4 = Final.)

Carotid flow evaluation. There is a tendency of decreased flow in C1 and C4 when compared with C1 and C3 (p = ). (C1 = Control; C2 = Biopump test; C3 = Biopump and intraaortic balloon pump test; C4 = Final.)
