Cardiac function before versus after surgery. Left ventricular end-diastolic volume index (LVEDVI) (a) and left ventricular end-systolic volume index (LVESVI) (b) were simultaneously measured using cardiac computed tomography (CCT), and left ventricular ejection fraction (LVEF) (c) was calculated. Left ventricular diastolic diameter (LVDd) (d), left ventricular systolic diameter (LVDs) (e), and LVEF (f) were measured on the echocardiography (echo) images
