    Abstract

    After weaning from mechanical circulatory support with extracorporeal membrane oxygenation or ventricular assist devices, patients may recurrently deteriorate and require reinstitution of support. Potential benefits of this desperate strategy are not well documented.
    We reviewed the hospital records of all patients in whom second-run mechanical circulatory support was instituted from May 1988 to August 2010.
    Second-run support was instigated in 26 (4.6%) of 567 patients who underwent short-term mechanical circulatory support. Underlying pathologies requiring support were cardiac in 20 patients (76.9%) and noncardiac in 6 patients (23.1%).The majority of patients were younger than 1 year old (73.1%, n=19). Fifteen patients (57.7%) survived second-run support, but only 7 patients (26.9%) survived to discharge from the hospital. After a median follow-up of 42.5 months (range, 16 to 66 months), 4 patients (15.4%) were alive, but 3 of them had various degrees of developmental delay.
    Selection of patients who can benefit from second-run support is a complex process with unpredictable results. Survival after second-run mechanical circulatory support in children is worse compared with single-run patients. Long-term prospects for survivors are so grim that this strategy should probably not be recommended.
