Abstract

The control of left ventricular assist device (LVAD) has been based on pressures of left ventricle (LV), aorta (AO) and pulmonary artery (PA) and flows in AO and PA. These parameters are one-dimensional and suitable for control of LVAD because they are numerical and quantitative. However, evaluation of the cardiac function by echocardiography is very useful in clinical settings because the cardiac function changes rapidly and dramatically. Transesophageal echocardiography is very useful for the assessment of cardiac function of the patients with LVAD implantation because it can detect and visualize what is happening in the heart immediately and directly.
