    AbstractUsing transesophageal echocardiography (TEE) we assessed left ventricular end-systolic elastance (Ees) during the pre- and post-cardiopulmonary bypass (CPB) periods in 10 patients undergoing an elective coronary artery bypass graft surgery. The end systolic volume of the left ventricle was obtained by TEE, and the end systolic pressure was obtained by the femoral artery pressure wave form. LVSWI decreased at post-CPB compared to the value at pre-CPB. There were no significant differences in cardiac output, ejection fraction and Ees between pre-CPB and post-CPB period. Intraoperative end-systolic pressure-volume relationship may be clinically useful to assess left ventricular function and also useful to confirm anesthetic management in patients who has undergone an coronary artery bypass graft surgery.
