“…2,6 Despite these limited case reports and few observational studies most of them provided limit information on indications and results of V-A ECLS support in this setting. 6,[9][10][11][12][13][14] The infarcted myocardial area may directly involve a PM or extend beyond the infarct-related artery (IRA) usually generating a sudden acute mitral valve regurgitation due to either chordae tethering, or partial/total PMR, often leading to hemodynamic instability or frank cardiogenic shock. This cardio-circulatory compromise might be refractory to conventional drug therapy or intra-aortic balloon implant, justifying the need for preoperative V-A ECLS.…”

“…Nowadays, in recent updated studies focused on trends and outcomes, the use of V‐A ECLS in complex post‐AMI MCs has shown promising results, acting as a bridge to surgery in the context of extreme hemodynamic compromise, like cardiac arrest or refractory cardiogenic shock 2,6 .

BackgroundPost‐acute myocardial infarction papillary muscle rupture (post‐AMI PMR) may present variable clinical scenarios and degree of emergency due to result of cardiogenic shock. Veno‐arterial extracorporeal life support (V‐A ECLS) has been proposed to improve extremely poor pre‐ or postoperative conditions. Information in this respect is scarce.MethodsFrom the CAUTION (meChanical complicAtion of acUte myocardial infarcTion: an InternatiOnal multiceNter cohort study) database (16 different Centers, data from 2001 to 2018), we extracted adult patients who were surgically treated for post‐AMI PMR and underwent pre‐ or/and postoperative V‐A ECLS support. The end‐points of this study were in‐hospital survival and ECLS complications.ResultsFrom a total of 214 post‐AMI PMR patients submitted to surgery, V‐A ECLS was instituted in 23 (11%) patients. The median age was 61.7 years (range 46–81 years). Preoperatively, ECLS was commenced in 10 patients (43.5%), whereas intra/postoperative in the remaining 13. The most common V‐A ECLS indication was post‐cardiotomy shock, followed by preoperative cardiogenic shock and cardiac arrest. The median duration of V‐A ECLS was 4 days. V‐A ECLS complications occurred in more than half of the patients. Overall, in‐hospital mortality was 39.2% (9/23), compared to 22% (42/219) for the non‐ECLS group.ConclusionsIn post‐AMI PMR patients, V‐A ECLS was used in almost 10% of the patients either to promote bridge to surgery or as postoperative support. Further investigations are required to better evaluate a potential for increased use and its effects of V‐A ECLS in such a context based on the still high perioperative mortality.
