AIMS: The long-term outcomes of patients treated with extracorporeal cardiopulmonary resuscitation (ECPR) for refractory ventricular tachycardia/ventricular fibrillation (VT/VF) out-of-hospital cardiac arrest (OHCA) remain poorly defined. The purpose of this study was to describe the hospital length of stay and long-term survival of patients who were successfully rescued with ECPR after refractory VT/VF OHCA.
METHODS AND RESULTS: In this retrospective cohort study, the length of index admission and long-term survival of patients treated with ECPR after OHCA at a single centre were evaluated. In a sensitivity analysis, survival of patients managed with left ventricular assist device (LVAD) implantation or heart transplantation during the same period was also evaluated. Between 1 January 2016 and 12 January 2020, 193 patients were transferred for ECPR considerations and 160 underwent peripheral veno-arterial extracorporeal membrane oxygenation cannulation. Of these, 54 (33.7%) survived the index admission. These survivors required a median 16 days of intensive care and 24 days total hospital stay. The median follow-up time of the survivors was 1216 (683, 1461) days. Of all, 79.6 and 72.2% were alive at 1 and 4 years, respectively. Most deaths within the first year occurred among the patients requiring discharge to a long-term acute care facility. Overall survival rates at 4 years were similar in the ECPR and LVAD cohorts (P = 0.30) but were significantly higher for transplant recipients (P < 0.001).
CONCLUSION: This data suggest that the lengthy index hospitalization required to manage OHCA patients with ECPR is rewarded by excellent long-term clinical outcomes in an expert ECPR programme.
