    AimsThere is no consensus on the optimal management of acute myocardial infarction due to acute left main coronary occlusion (LMCO). We evaluated the feasibility of primary percutaneous coronary intervention (PCI) for acute LMCO in an institution without on-site cardiothoracic surgical (CTS) support.Methods And ResultsWe retrospectively identified 20 patients, median age 67 years (range 38 to 81). Sixteen patients presented with cardiogenic shock. All patients required intra-aortic balloon pump counterpulsation and inotropic support. Sixteen patients underwent stenting and four had balloon angioplasty only. Thrombolysis In Myocardial Infarction 3 flow was restored in 13 patients. Post-PCI, six patients were transferred to a tertiary institution for further care: three underwent extracorporeal membrane oxygenation (ECMO), one underwent both ECMO and coronary artery bypass grafting (CABG), one died before ECMO initiation and one stabilised without further intervention. Thirteen patients died in-hospital. There was one subsequent death out of the seven hospital survivors, with median follow-up 390 days (range 60 to 660 days). There was a trend towards survival with a shorter door-to-balloon time (p = 0.07).ConclusionsPrimary PCI may be a feasible initial revascularisation strategy for acute LMCO in centres without on-site CTS support.
