Postcardiotomy Venoarterial Extracorporeal Membrane Oxygenation With and Without Intra-Aortic Balloon Pump
Publisher Copyright: © 2022 The Author(s)Objectives: To compare the outcomes of patients with postcardiotomy shock treated with venoarterial extracorporeal membrane oxygenation (VA-ECMO) only compared with VA-ECMO and intra-aortic balloon pump (IABP). Design: A retrospective multicenter registry study. Setting: At 19 cardiac surgery units. Participants: A total of 615 adult patients who required VA-ECMO from 2010 to 2018. The patients were divided into 2 groups depending on whether they received VA-ECMO only (ECMO only group) or VA-ECMO plus IABP (ECMO-IABP group). Measurements and Main Results: The overall series mean age was 63 +/- 13 years, and 33% were female. The ECMO-only group included 499 patients, and 116 patients were in the ECMO-IABP group. Urgent and/or emergent procedures were more common in the ECMO-only group. Central cannulation was performed in 47% (n = 54) in the ECMO-IABP group compared to 27% (n = 132) in the ECMO-only group. In the ECMOIABP group, 58% (n = 67) were successfully weaned from ECMO, compared to 46% (n = 231) in the ECMO-only group (p = 0.026). However, inhospital mortality was 63% in the ECMO-IABP group compared to 65% in the ECMO-only group (p = 0.66). Among 114 propensity score-matched pairs, ECMO-IABP group had comparable weaning rates (57% v 53%, p = 0.51) and in-hospital mortality (64% v 58%, p = 0.78). Conclusions: This multicenter study showed that adjunctive IABP did not translate into better outcomes in patients treated with VA-ECMO for postcardiotomy shock. (C) 2022 The Author(s).

Postcardiotomy Venoarterial Extracorporeal Membrane Oxygenation in Patients Aged 70 Years or Older
Background. There is uncertainty whether venoarterial extracorporeal membrane oxygenation (VA-ECMO) should be used in older patients with cardiopulmonary failure after cardiac surgery.Methods. This was a retrospective multicenter study of 781 patients who required postcardiotomy VA-ECMO for cardiopulmonary failure after adult cardiac surgery from 2010 to 2018 at 19 cardiac surgery centers. A parallel systematic review with meta-analysis of the literature was performed.Results. The hospital mortality in the overall Post-cardiotomy Venoarterial Extracorporeal Membrane Oxygenation (PC-ECMO) series was 64.4%. A total of 255 patients were 70 years old or older (32.7%), and their hospital mortality was significantly higher than in younger patients (76.1% vs 58.7%; adjusted odds ratio, 2.199; 95% confidence interval [CI], 1.536 to 3.149). Arterial lactate level greater than 6 mmol/L before starting VA-ECMO was the only predictor of hospital mortality among patients 70 years old or older in univariate analysis (82.6% vs 70.4%; P = .029). Meta-analysis of current and previous studies showed that early mortality after postcardiotomy VA-ECMO was significantly higher in patients aged 70 years or older compared with younger patients (odds ratio, 2.09; 95% CI, 1.59 to 2.75; 5 studies including 1547 patients; I-2, 5.9%). The pooled early mortality rate among patients aged 70 years or older was 78.8% (95% CI, 74.1 to 83.5; 6 studies including 617 patients; I-2, 41.8%). Two studies reported 1-year mortality (including hospital mortality) of 79.9% and 75.6%, respectively, in patients 70 years old or older.Conclusions. Advanced age should not be considered a contraindication for postcardiotomy VA-ECMO. However, in view of the high risk of early mortality, meaningful scrutiny is needed before using VA-ECMO after cardiac surgery in older patients. (C) 2019 by The Society of Thoracic Surgeon

Five-year survival after post-cardiotomy veno-arterial extracorporeal membrane oxygenation
Aims Veno-arterial (VA) extracorporeal membrane oxygenation (ECMO) support for post-cardiotomy cardiogenic shock (PCS) after adult cardiac surgery is associated with satisfactory hospital survival. However, data on long-term survival of these critically ill patients are scarce.Methods and results Between January 2010 and March 2018, 665 consecutive patients received VA-ECMO for PCS at 17 cardiac surgery centres and herein we evaluated their 5-year survival. The mean follow-up of this cohort was 1.72.7years (for hospital survivors, 4.62.5years). In this cohort, 240 (36.1%) patients survived to hospital discharge. Five-year survival of all patients was 27.7%. The PC-ECMO score was predictive of 5-year survival in these patients (0 point, 50.9%; 1 point, 44.9%; 2 points, 40.0%; 3 points, 34.7%; 4 points, 21.0%; 5 points, 17.6%; >= 6 points, 10.7%; P<0.0001). Age was among factors independently associated with late survival, patients >70 years old having a remarkably poor 5-year survival (<60 years: 39.2%; 60-69years: 29.9%; 70-79years: 12.3%; >= 80 years: 13.0%, P<0.0001). Implantation of a ventricular assist device or heart transplant was performed in 3.2% of patients and their 5-year survival was 42.9% (for heart transplant, 63.6%).Conclusion Veno-arterial extracorporeal membrane oxygenation for PCS is associated with satisfactory 5-year survival in young patients without critical pre-ECMO conditions. The use of VA-ECMO for PCS in patients >70 years should be considered only after a judicious scrutiny of patient's life expectancy. Future studies should evaluate whether satisfactory mid-term survival of these patients translates into a good functional outcome
Gender and the Outcome of Postcardiotomy Veno-arterial Extracorporeal Membrane Oxygenation
Objective: There is a paucity of sex-specific data on patients’ postcardiotomy venoarterial extracorporeal membrane oxygenation (VA-ECMO). The present study sought to assess this issue in a multicenter study. Design: Retrospective, propensity score–matched analysis of an international registry. Setting: Multicenter study, tertiary university hospitals. Participants: Data on adult patients undergoing postcardiotomy VA-ECMO. Measurements and Main Results: Between January 2010 and March 2018, patients treated with postcardiotomy VA-ECMO at 17 cardiac surgery centers were analyzed. Index procedures considered were coronary artery bypass graft surgery, isolated valve surgery, their combination, and proximal aortic root surgery. Hospital and five-year mortality constituted the endpoints of interest. Propensity score matching was adopted with logistic regression. A total of 358 patients (mean age: 63.3 ± 12.3 years; 29.6% female) were identified. Among 94 propensity score–matched pairs, women had a higher hospital mortality (70.5% v 56.4%, p = 0.049) compared with men. Logistic regression analysis showed that women (odds ratio [OR], 1.87; 95% confidence interval [CI] 1.10-3.16), age (OR, 1.06; 95%CI 1.04-1.08) and pre-ECMO arterial lactate (OR, 1.09; 95%CI 1.04-1.16) were independent predictors of hospital mortality. No differences between female and male patients were observed for other outcomes. Among propensity score–matched pairs, one-, three-, and five-year mortality were 60.6%, 65.0%, and 65.0% among men, and 71.3%, 71.3%, and 74.0% among women, respectively (p = 0.110, adjusted hazard ratio, 1.27; 95%CI 0.96-1.66). Conclusions: In postcardiotomy VA-ECMO, female patients demonstrated higher hospital mortality than men. Morbidity and late mortality were similar between the two groups
Outcome of Repeat Venoarterial Extracorporeal Membrane Oxygenation in Postcardiotomy Cardiogenic Shock
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
Neurologic Injury in Patients Treated With Extracorporeal Membrane Oxygenation for Postcardiotomy Cardiogenic Shock
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
Duration of Venoarterial Extracorporeal Membrane Oxygenation and Mortality in Postcardiotomy Cardiogenic Shock
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
Multicenter study on postcardiotomy venoarterial extracorporeal membrane oxygenation
Objectives: The aim of this study was to identify the risk factors associated with early mortality after postcardiotomy venoarterial extracorporeal membrane oxygenation. Methods: This is an analysis of the postcardiotomy extracorporeal membrane oxygenation registry, a retrospective multicenter cohort study including 781 patients aged more than 18 years who required venoarterial extracorporeal membrane oxygenation for cardiopulmonary failure after cardiac surgery from 2010 to 2018 at 19 cardiac surgery centers. Results: After a mean venoarterial extracorporeal membrane oxygenation therapy of 6.9 ± 6.2 days, hospital and 1-year mortality were 64.4% and 67.2%, respectively. Hospital mortality after venoarterial extracorporeal membrane oxygenation therapy for more than 7 days was 60.5% (P = .105). Centers that had treated more than 50 patients with postcardiotomy venoarterial extracorporeal membrane oxygenation had a significantly lower hospital mortality than lower-volume centers (60.7% vs 70.7%, adjusted odds ratio, 0.58; 95% confidence interval, 0.41-0.82). The postcardiotomy extracorporeal membrane oxygenation score was derived by assigning a weighted integer to each independent pre–venoarterial extracorporeal membrane oxygenation predictors of hospital mortality as follows: female gender (1 point), advanced age (60-69 years, 2 points; ≥70 years, 4 points), prior cardiac surgery (1 point), arterial lactate 6.0 mmol/L or greater before venoarterial extracorporeal membrane oxygenation (2 points), aortic arch surgery (4 points), and preoperative stroke/unconsciousness (5 points). The hospital mortality rates according to the postcardiotomy extracorporeal membrane oxygenation score was 0 point, 45.6%; 1 point, 40.5%; 2 points, 51.1%; 3 points, 57.8%; 4 points, 70.7%; 5 points, 68.3%; 6 points, 77.5%; and 7 points or more, 89.7% (P < .0001). Conclusions: Age, female gender, prior cardiac surgery, preoperative acute neurologic events, aortic arch surgery, and increased arterial lactate were associated with increased risk of early mortality after postcardiotomy venoarterial extracorporeal membrane oxygenation. Center experience with postcardiotomy venoarterial extracorporeal membrane oxygenation may contribute to improved results
