AbstractA 58 year-old male was scheduled for surgery of his hepatic cancer. Tumor invaded to the right atrium through the inferior vena cava. The operative method of removing the tumor in the right atrium was scheduled under extracorporeal circulation after the left lobe hepatectomy. Since there was a tumor in the right atrium, central venous pressure monitoring could not be reliable. Transesophageal echocardiography (TEE) was employed in order to detect the part of the tumor flowing into the pulmonary artery or occluding the tricuspid valve. Due to massive blood loss during hepatectomy, the capacity in the right atrium decreased and the tumor was often about to engage the tricuspid valve. After the rapid fluid therapy, the right atrium capacity increased preventing the engagement of the tumor. TEE was useful not only to observe the movement of the tumor in the right atrium but also to monitor the circulating blood volume.
