Femoral arterial cannulation in adult venoarterial (VA) extracorporeal membrane oxygenation (ECMO) predisposes patients to ipsilateral limb ischemia. Placement of a distal perfusion catheter (DPC) is one of few techniques available to prevent or manage this complication. Although frequently used, the indications for and timing of DPC placement are poorly characterized, and no guidelines are available to guide its use. ⋯ In-hospital mortality was comparable between groups. DPC placement at the time of primary cannulation may lower the incidence of limb ischemia. The benefit of DPC placement once evidence of limb ischemia is apparent remains unclear.

Meta Analysis
Del Nido Cardioplegia for Myocardial Protection in Adult Cardiac Surgery: A Systematic Review and Meta-Analysis.
Cardioplegia is an important strategy for myocardial protection during cardiac surgery. This meta-analysis was to compare the effects of del Nido and conventional cardioplegia in adult patients. Systematic searches were performed to identify studies using PubMed, Embase, the Cochrane Library, and the International Clinical Trials Registry Platform. ⋯ Ventilation time and length of intensive care unit were decreased significantly with del Nido cardioplegia (MD: -1.05, 95% CI: -1.79 to -0.31, p = 0.006; MD: -0.65, 95% CI: -0.92 to -0.38, p < 0.00001). There were no differences in myocardial enzyme, postoperative inotropic support, atrial fibrillation, hospital, and mortality between the two groups. In adult cardiac surgery, myocardial protection used with the del Nido or conventional cardioplegia solution yield similar short-term clinical outcomes.

Case Reports
Heartmate III Replacement for Recurring Left Ventricular Assist Device Pump Thrombosis.
Left ventricular assist devices (LVADs) are being used widely to support patients with advanced systolic heart failure. Some of these patients will need more than one LVAD replacement due to pump thrombosis. The Heartmate III LVAD (Abbott Inc, Chicago, IL) recently has been shown to have a very low incidence of pump thrombosis. In this article, we describe cases of patients with multiple pump thrombosis events, who were successfully replaced with the Heartmate III.

In several case reports and case series, extracorporeal membrane oxygenation during chest compression (CPR) has been shown to be a reasonable tool to improve outcome of patients under resuscitation. Although recommendations for extracorporeal cardiopulmonary resuscitation (ECPR) include younger patients with shockable rhythm and short previous CPR-time, it remains unclear if nonhighly selected patients have a similar outcome. Aim of this study was to determine outcome in our nonhighly selected patient population treated with ECPR and investigate possible predictors of survival. ⋯ Mean CPR-time was 41.1 minutes (interquartile range, ±29.25 minutes). Extracorporeal membrane oxygenation seems to be a useful tool to improve the outcome of CPR also in nonhighly selected patients when compared with CPR alone and could be considered in patients with refractory cardiac arrest also after longer previous CPR-time. Serum lactate and heart rhythm should be taken into account for patient selection.
