Our goal was to compare the efficacy of two left ventricular assist devices on resuscitation and hemodynamic supply in a porcine model of ventricular fibrillation (VF) cardiac arrest. Methods: Seventeen anaesthetized pigs had 12 min of untreated VF followed by 6 min of chest compression and boluses of epinephrine. Next, a first defibrillation was attempted and pigs were randomized to any of the three groups: control (n = 5), implantation of an percutaneous left ventricular assist device (Impella, n = 5) or extracorporeal membrane oxygenation (ECMO, n = 7). Hemodynamic and myocardial functions were evaluated invasively at baseline, at return of spontaneous circulation (ROSC), after 10\u201330\u201360\u2013120\u2013240 min post-resuscitation. The primary endpoint was the rate of ROSC. Results: Only one of 5 pigs in the control group, 5 of 5 pigs in the Impella group, and 5 of 7 pigs in the ECMO group had ROSC (p &lt; 0.05). Left ventricular ejection fraction at 240 min post-resuscitation was 37.5 \u00b1 6.2% in the ECMO group vs. 23 \u00b1 3% in the Impella group (p = 0.06). No significant difference in hemodynamic parameters was observed between the two ventricular assist devices. Conclusion: Early mechanical circulatory support appeared to improve resuscitation rates in a shockable rhythm model of cardiac arrest. This approach appears promising and should be further evaluated.<\/jats:p>","DOI":"10.3390\/jcm10163623","type":"journal-article","created":{"date-parts":[[2021,8,17]],"date-time":"2021-08-17T03:43:04Z","timestamp":1629171784000},"page":"3623","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Severe Myocardial Dysfunction after Non-Ischemic Cardiac Arrest: Effectiveness of Percutaneous Assist Devices"],"prefix":"10.3390","volume":"10","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0703-1331","authenticated-orcid":false,"given":"St\u00e9phane","family":"Manzo-Silberman","sequence":"first","affiliation":[{"name":"Department of Cardiology, Lariboisi\u00e8re Hospital, Assistance Publique-H\u00f4pitaux de Paris (AP-HP), Denis Diderot University, INSERM UMRS 942, 75010 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3115-9255","authenticated-orcid":false,"given":"Christoph","family":"Nix","sequence":"additional","affiliation":[{"name":"Abiomed Europe GmbH, Neuenhofer Weg 3, D-52074 Aachen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andreas","family":"Goetzenich","sequence":"additional","affiliation":[{"name":"Abiomed Europe GmbH, Neuenhofer Weg 3, D-52074 Aachen, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pierre","family":"Demondion","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular and Thoracic Surgery, Institute of Cardiology, Piti\u00e9-Salp\u00eatri\u00e8re Hospital, Assistance Publique-H\u00f4pitaux de Paris (AP-HP), Sorbonne University, 47-83 Boulevard de l\u2019H\u00f4pital, 75013 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chantal","family":"Kang","sequence":"additional","affiliation":[{"name":"XP-MED, 78100 Saint Germain en Laye, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michel","family":"Bonneau","sequence":"additional","affiliation":[{"name":"XP-MED, 78100 Saint Germain en Laye, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alain","family":"Cohen-Solal","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Lariboisi\u00e8re Hospital, Assistance Publique-H\u00f4pitaux de Paris (AP-HP), Denis Diderot University, INSERM UMRS 942, 75010 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pascal","family":"Leprince","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular and Thoracic Surgery, Institute of Cardiology, Piti\u00e9-Salp\u00eatri\u00e8re Hospital, Assistance Publique-H\u00f4pitaux de Paris (AP-HP), Sorbonne University, 47-83 Boulevard de l\u2019H\u00f4pital, 75013 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guillaume","family":"Lebreton","sequence":"additional","affiliation":[{"name":"Department of Cardiovascular and Thoracic Surgery, Institute of Cardiology, Piti\u00e9-Salp\u00eatri\u00e8re Hospital, Assistance Publique-H\u00f4pitaux de Paris (AP-HP), Sorbonne University, 47-83 Boulevard de l\u2019H\u00f4pital, 75013 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2021,8,17]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"e67","DOI":"10.1161\/CIR.0000000000000558","article-title":"Heart Disease and Stroke Statistics-2018 Update: A Report from the American Heart Association","volume":"137","author":"Benjamin","year":"2018","journal-title":"Circulation"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1304","DOI":"10.1056\/NEJM200104263441707","article-title":"Cardiac resuscitation","volume":"344","author":"Eisenberg","year":"2001","journal-title":"N.
