    Abstract:
    A 74-year-old man had an previous antero-septal and inferior myocardial infarction and an abdominal aortic aneurysm (AAA) 48 mm in diameter. Coronary angiography showed obstruction of the left anterior descending artery and of the right coronary artery, and 95% stenosis of the circumflex artery. The value of an ejection fraction of the left ventricle was 33%, measured by left venticulography. CABG and replacement of the aneurysm were performed simultaneously, because of the necessity of an intra-aortic balloon pumping (IABP) due to the impaired left ventricular function. First, CABG was performed under cardiac arrest. After declamping the ascending aorta, subsequently, replacement of AAA was performed while extracorporeal circulation (ECC) assisted heart beating. Weaning from ECC was smooth, and the operation was successful without using IABP. The patient was discharged 32 days after the operation. Consequently, cardiopulmonary bypass during AAA operation could decrease heart loads when hemodynamic states change in aortic clamping or after declamping. A simultaneous operation of CABG and AAA using ECC is safe and effective for impaired left ventricular function.
