[Successful treatment of myocardial infarction of left main trunk by emergent CABG under IABP and PCPS support].
We experienced a successful treatment of acute myocardial infarction which was due to left main trunk obstruction. A 54-year-old man with no history of angina was transported by a rescue squad in cardiogenic shock, and diagnosed by electrocardiography with a wide range of myocardial infarction. Emergent coronary arteriography was performed under IABP support, revealing 99% stenosis in the left main trunk. Percutaneous transluminal coronary recanalization (PTCR) was performed, but suddenly cardiac arrest was happened. He was put on emergency percutaneous cardiopulmonary support (PCPS). A Palmaz-Schatz stent was implanted for reperfusion, but the patient was hemodynamically unstable with frequent ventricular arrhythmia and pulmonary edema. 24 hours later he underwent coronary artery bypass grafting and CPB could be terminated intraoperatively. His cardiac function was very low and LVEF was 20%. All grafts were patent. On the rehabilitation he was discharged on postoperative day 162 and has returned to work in his office one year postoperatively.
