A 61-year-old male presented to our emergency room with chest tightness, dyspnea, and cold sweat. He underwent a 12-lead EKG which showed ST-elevation from leads V1-V4 and T wave inversion in leads II, III, and aVF. His troponin-I level was elevated to 70.3 ng/ml. He went into cardiogenic shock when he was in the catheter room. After advanced cardiac life support was administered for 30 min, veno-arterial extracorporeal membrane oxygenation (VA-ECMO) cannulation was set up using 21-french arterial and 21-french venous cannula through the right femoral artery and right femoral vein by the puncture method for hemodynamic support. Subsequently, a coronary artery bypass graft (CABG) for acutemyocardial infarctionwas performed. However, the patientwas unable to beweaned from the VA-ECMO. Four days later, a CentriMag (Levitronix LLC, Waltham, MA, USA) left ventricular assist device (LVAD) was applied to avoid ECMO-related complications such as severe hemolysis, ischemic, deteriorated liver and renal function. The patient subsequently underwent a successful orthotopic heart transplant after 87 days on the CentriMag LVAD. The patient was extubated on the next postoperative day and was discharged 2 weeks later.
