Background The optimal venoarterial extracorporeal membrane oxygenation (VA ECMO) cannulation strategy in patients with postcardiotomy cardiogenic shock is still debatable. Studies evaluating the effect of cannulation strategy on long-term survival are scarce. Objectives We investigated the impact of central versus peripheral cannulation strategy for ECMO insertion on hospital outcomes and survival in postcardiotomy cardiogenic shock patients. Methods This retrospective study involved 101 patients who had either central or peripheral ECMO due to postcardiotomy shock between June 2009 and December 2020. Study endpoints were limb ischemia, bleeding, blood transfusion, wound infection, and overall survival. Results Eighty-four patients received central (c) ECMO, and 17 patients had peripheral (p) ECMO. In the group of pECMO, limb ischemia was significantly higher (5 [29.41%] vs 6 [7.14%]; p = .01). Other endpoints were similar in both groups. Thirty-day mortality was nonsignificantly different between both cohorts (cECMO 34 [41.67%] vs pECMO 10 [58.82%]; p = .29). However, overall survival was better with cECMO (Log-rank p = .02). Patients’ age [HR: 1.04 (95% CI: 1.02–1.06); p = .001], pECMO [HR: 1.98 (95% CI: 1.11–3.55), p = .002] and presence of infective endocarditis [HR: 3.54 (95% CI: 1.52–8.24), p = .03] were significant predictors of overall mortality. Conclusions Peripheral ECMO was associated with an increased risk of limb ischemia; however, bleeding, blood transfusion, infection, and 30-day mortality were comparable to central ECMO. Central cannulation was associated with a better 1-year survival rate. Therefore, central cannulation might be the preferred strategy for patients with postcardiotomy cardiogenic shock.

We aimed to compare the outcomes of ECMO with and without IABP for postcardiotomy cardiogenic shock. The study included 103 patients who needed ECMO for postcardiotomy cardiogenic shock. Patients were grouped according to the use of IABP into ECMO without IABP ( n = 43) and ECMO with IABP ( n = 60). The study endpoints were hospital complications, successful weaning, and survival. Patients with IABP had lower preoperative ejection fraction ( p = 0.002). There was no difference in stroke ( p = 0.97), limb ischemic ( p = 0.32), and duration of ICU stay ( p = 0.11) between groups. Successful weaning was non-significantly higher with IABP (36 (60%) vs 19 (44.19%); p = 0.11). Predictors of successful weaning were inversely related to the high pre-ECMO lactate levels (OR: 0.89; p = 0.01), active endocarditis (OR: 0.06; p = 0.02), older age (OR: 0.95; p = 0.02), and aortic valve replacement (OR: 0.26; p = 0.04). There was no difference in survival between groups ( p = 0.80). Our study did not support the routine use of IABP during ECMO support.

Background: Sepsis could affect the outcomes of patients with postcardiotomy cardiogenic shock supported with extracorporeal membrane oxygenation (ECMO). Our objectives were to characterize sepsis patients with ECMO support for postcardiotomy cardiogenic shock and assess its predictors and effect on patients’ outcomes. Methods: This retrospective study included 103 patients with ECMO for postcardiotomy cardiogenic shock from 2009 to 2020. Patients were divided according to the occurrence and timing of sepsis into three groups. Group 1 included patients with no sepsis ( n = 67), Group 2 included patients with ECMO-related sepsis ( n = 10), and Group 3 included patients with non-ECMO-related sepsis ( n = 26). Results: Lactate level before ECMO was highest in the ECMO-associated sepsis group (Group 1 and 2 p = 0.003 and Group 2 and 3 p = 0.003). Dialysis and gastrointestinal bleeding were highest in ECMO-associated sepsis ( p = 0.03 and 0.04, respectively). Blood transfusion was higher in ECMO-associated sepsis than in patients with no sepsis ( p = 0.01). Mortality was nonsignificantly higher in patients with ECMO-associated sepsis. High BMI (OR: 1.11; p = 0.004), preoperative dialysis (OR: 7.35; p = 0.02), preoperative IABP (OR: 9.9.61; p = 0.01) and CABG (OR: 6.29; p = 0.01) were significantly associated with sepsis. Older age (OR: 1.08; p = 0.004), lower BSA (OR: 0.004; p = 0.003), peripheral cannulation (OR: 29.82; p = 0.03), and high pre ECMO lactate level (OR: 1.24; p = 0.001) were associated with increased mortality. Sepsis did not predict mortality (OR: 1.83; p = 0.21). Conclusions: Sepsis is a dreaded complication in patients with postcardiotomy cardiogenic shock, especially ECMO-associated sepsis. Preoperative risk factors could predict postoperative sepsis in ECMO patients.

Management of patients with end‐stage heart failure is still challenging. We report a case of idiopathic dilated cardiomyopathy who went through a challenging course. The case was presented as acute heart failure syndrome, which rapidly declined into cardiogenic shock and cardiac arrest that required an extracorporeal membrane oxygenator, then biventricular assist device implantation for circulatory support. The course was complicated with severe gastrointestinal bleeding and multiorgan failure until achieving full cardiac and organ recovery. The left ventricle ejection fraction improved from 10% to 50% at discharge.
