A 54-year-old man was referred to a local hospital, located about 90 km from our hospital, with cardiogenic shock due to left main coronary artery infarction (LMCA-MI). Percutaneous coronary intervention (PCI) was performed under intra-aortic balloon pumping (IABP) support, but resulted in insufficient reperfusion and his condition worsened. The helicopter emergency medical service (HEMS) rapidly transported the patient to our hospital. After percutaneous cardio-pulmonary support system (PCPS) insertion, PCI could establish the coronary flow. A series of intensive therapies saved the patient. The cooperation of medical and emergency service system following revascularization and intensive care saved the patient with LMCA-MI accompanied by cardiogenic shock.
