OBJECTIVES: Postcardiotomy cardiogenic shock (PCCS) is associated with high mortality rates of 50-80%. Although veno-arterial extracorporeal membrane oxygenation has been used as mechanical circulatory support in patients with PCCS, it is associated with a high rate of complications and poor quality of life. The Impella 5.0 and Impella Left Direct (LD) (Impella 5.0/LD) are minimally invasive left ventricular assist devices that provide effective haemodynamic support resulting in left ventricular unloading and systemic perfusion. Our goal was to describe the outcome of patients with PCCS supported with the Impella 5.0/LD at La Pitié-Salpêtrière Hospital. METHODS: We retrospectively reviewed consecutive patients supported with the Impella 5.0/LD for PCCS between December 2010 and June 2015. Survival outcome and in-hospital complications were assessed. RESULTS: A total of 29 patients (63 ± 14 years, 17% women) with PCCS were supported with the Impella 5.0/LD. At baseline, 69% experienced chronic heart failure, 66% had dilated cardiomyopathy and 57% had valvular disease. The mean EuroSCORE II was 22 ± 17 and the ejection fraction was 28 ± 11%. Most of the patients underwent isolated valve surgery (45%) or isolated coronary artery bypass grafting (38%). The mean duration of Impella support was 9 ± 7 days. Weaning from the Impella was successful in 72.4%, and 58.6% survived to discharge. Recovery of native heart function was observed in 100% of discharged patients. Survival to 30 days and to 1 year from Impella implant was 58.6% and 51.7%, respectively. CONCLUSIONS: The Impella 5.0 and the Impella LD represent an excellent treatment option for critically ill patients with PCCS and are associated with favourable survival outcome and native heart recovery.
