Abstract
A 49-year-old man with impaired left ventricular function successfully underwent a one-stage operation of coronary artery bypass grafting (CABG) and replacement of infrarenal abdominal aortic aneurysm (AAA). Left ventricular ejection fraction, left ventricular end-diastolic and mean pulmonary artery pressures were 24%, 25mmHg and 33mmHg, respectively. The AAA was 6cm in diameter and accompanied by bilateral common iliac artery aneurysm. After completion of CABG, AAA replacement was performed during extracorporeal circulation. There were no hemodynamic changes associated with aortic clamping or declamping under the mechanical cardiac assist during AAA surgery. This procedure appeared to be a feasible one-stage procedure in patients with AAA and coronary artery disease accompanied by impaired left ventricular function.
