[Successful Use of Left Ventricular Support Device (Impella 5.0) for Ischemic Heart Disease with Cardiogenic Shock:Report of a Case].

Postoperative hemodynamic support with an Impella 5.0 was effective in an obese man who underwent coronary artery bypass grafting (CABG) for ischemic heart disease and cardiogenic shock. A 43-year-old obese man presented to our hospital complaining severe chest pain. Coronary angiography revealed acute coronary syndrome due to severe triple-vessel disease, and the patient fell into a state of shock, which required veno-arterial extracorporeal membrane oxygenation (VA-ECMO) support. The patient subsequently underwent CABG, but he was unable to be separated from VA-ECMO. Impella 5.0 was introduced through right axillary artery on the next day. VA-ECMO was converted to veno-venous (VV)-ECMO on the 3rd postoperative day to enable respiratory rehabilitation in a sitting posi-tion;his respiratory status gradually improved. VV-ECMO and the Impella 5.0 were discontinued on the 6th and 7th postoperative days, respectively. He was eventually transferred to nearby facility for further rehabilitation three months later. As of two years, his cardiac function has improved and he is doing well at home.
