BACKGROUND: RotaFlow and Levitronix CentriMag veno-arterial extracorporeal membrane oxygenation (ECMO) support systems have been investigated as treatment for refractory cardiogenic shock (CS).
METHODS: Between 2004 and 2012, 119 consecutive adult patients were supported on RotaFlow (n = 104) or CentriMag (n = 15) ECMO at our institution (79 men; age 57.3 ± 12.5 years, range:19-78 years). Indications for support were: failure to wean from cardiopulmonary bypass in the setting of postcardiotomy (n = 47) and primary graft failure (n = 26); post-acute myocardial infarction CS (n = 11); acute myocarditis (n = 3); and CS on chronic heart failure (n = 32).
RESULTS: A central ECMO setting was established in 64 (53.7%) patients while peripherally in 55 (46.2%). Overall mean support time was 10.9 ± 8.7 days (range:1-43 days). Forty-two (35.2%) patients died on ECMO. Overall success rate, in terms of survival on ECMO (n = 77), weaning from mechanical support (n = 51;42.8%) and bridge to heart transplantation (n = 26;21.8%), was 64.7%. Sixty-eight (57.1%) patients were successfully discharged. Stepwise logistic regression identified blood lactate level and CK-MB relative index at 72 h after ECMO initiation, and number of packed red blood cells (PRBCs) transfused on ECMO as significant predictors of mortality (p = 0.011, odds ratio [OR] = 2.48; 95% confidence interval [CI] = 1.11-3.12; p = 0.012, OR = 2.81, 95% CI = 1.02-2.53; and p = 0.012, OR = 1.94; 95% CI = 1.02-5.21; respectively). Central ECMO population had a higher rate of continuous veno-venous hemofiltration (CVVH) need and bleeding events when compared with the peripheral setting.
CONCLUSIONS: Patients with a poor hemodynamic status may benefit by rapid insertion of veno-arterial ECMO. The blood lactate level, CK-MB relative index and PRBCs transfused should be strictly monitored during ECMO support.
