- Objective: The optimal duration of venoarterial extracorporeal membrane oxygenation (VA-ECMO) in patients affected by postcardiotomy cardiogenic shock (PCS) remains controversial. The present study was conducted to investigate the effect of VA-ECMO duration on hospital outcomes. Design: Retrospective analysis of an international registry. Setting: Multicenter study including 19 tertiary university hospitals. Participants: Between January 2010 and March 2018, data on PCS patients receiving VA-ECMO were retrieved from the multicenter PC-ECMO registry. Interventions: Patients were stratified according to the following different durations of VA-ECMO therapy: ≤three days, four-to-seven days, eight-to-ten days, and >ten days. Measurements and Main Results: A total of 725 patients, with a mean age of 62.9 ± 12.9 years, were included. The mean duration of VA-ECMO was 7.1 ± 6.3 days (range 0-39 d), and 39.4% of patients were supported for ≤three days, 29.1% for four-seven days, 15.3% for eight-ten days, and finally 20.7% for >ten days. A total of 391 (53.9%) patients were weaned from VA-ECMO successfully; however, 134 (34.3%) of those patients died before discharge. Multivariate logistic regression showed that prolonged duration of VA-ECMO therapy (four-seven days: adjusted rate 53.6%, odds ratio [OR] 0.28, 95% confidence interval [CI] 0.18-0.44; eight-ten days: adjusted rate 61.3%, OR 0.51, 95% CI 0.29-0.87; and >ten days: adjusted rate 59.3%, OR 0.49, 95% CI 0.31-0.81) was associated with lower risk of mortality compared with VA-ECMO lasting ≤three days (adjusted rate 78.3%). Patients requiring VA-ECMO therapy for eight-ten days (OR 1.96, 95% CI 1.15-3.33) and >10 days (OR 1.85, 95% CI 1.14-3.02) had significantly greater mortality compared with those on VA-ECMO for 4 to 7 days. Conclusions: PCS patients weaned from VA-ECMO after four-seven days of support had significantly less mortality compared with those with shorter or longer mechanical support.

- Objective: To investigate the frequency, predictors, and outcomes of neurologic injury in adults treated with postcardiotomy extracorporeal membrane oxygenation (PC-ECMO). Design: A retrospective multicenter registry study. Setting: Twenty-one European institutions where cardiac surgery is performed. Participants: A total of 781 adult patients who required PC-ECMO during 2010 to 2018 were divided into patients with neurologic injury (NI) and patients without neurologic injury (NNI). Measurements and Main Results: Baseline and operative data, in-hospital outcomes, and long-term survival were compared between the NI and the NNI groups. Predictors of neurologic injury were identified. A subgroup analysis according to the type of neurologic injury was performed. Overall, NI occurred in 19% of patients in the overall series, but the proportion of patients with NI ranged from 0% to 65% among the centers. Ischemic stroke occurred in 84 patients and hemorrhagic stroke in 47 patients. Emergency procedure was the sole independent predictor of NI. In-hospital mortality was higher in the NI group than in the NNI group (79% v 61%, p < 0.001). The one-year survival was lower in the NI group (17%) compared with the NNI group (37%). Long-term survival did not differ between patients with ischemic stroke and those with hemorrhagic stroke. Conclusion: Neurologic injury during PC-ECMO is common and associated with a dismal prognosis. There is considerable interinstitutional variation in the proportion of neurologic injury in PC-ECMO-treated adults. Well-known risk factors for stroke are not associated with neurologic injury in this setting.

- Objective: Data on patients requiring a second run of venoarterial extracorporeal membrane oxygenation (VA-ECMO) support in patients affected by postcardiotomy cardiogenic shock (PCS) are very limited. The authors aimed to investigate the effect of a second run of VA-ECMO on PCS patient survival. Design: Retrospective analysis of an international registry. Setting: Multicenter study, tertiary university hospitals. Participants: Data on adult PCS patients receiving a second run of VA-ECMO. Measurements and Main Results: A total of 674 patients with a mean age of 62.9 ± 12.7 years were analyzed, and 21 (3.1%) patients had a second run of VA-ECMO. None of them required more than two VA-ECMO runs. The median duration of VA-ECMO therapy was 135 hours (interquartile range [IQR] 61-226) in patients who did not require a VA-ECMO rerun. In the rerun VA-ECMO group the median overall duration of VA-ECMO therapy was 183 hours (IQR 107-344), and the median duration of the first run was 114 hours (IQR 66-169). Nine (42.9%) of the patients who required a second run of VA-ECMO died during VA-ECMO therapy, whereas five (23.8%) survived to hospital discharge. No differences between patients treated with single or second VA-ECMO runs were observed in terms of hospital mortality and late survival. In patients requiring a second VA-ECMO run, the actuarial survival estimates at three and 12 months after VA-ECMO weaning were 23.8% ± 9.3% and 19.6% ± 6.4%, respectively. Conclusions: Repeat VA-ECMO therapy is a valid treatment strategy for PCS patients. Early and late survivals are similar between patients who have undergone a single or second run of VA-ECMO.
