Sejong General Hospital (SJH), designated as the only hospital specializing in cardiovascular disorders by the Ministry of Health and Welfare in Korea, constantly strives to treat better heart diseases. Recently SJH has introduced da Vinci Si system, the heart surgery robot, for the first time among specialized hospitals in Korea and has invested heavily in medical equipment. Actually cardiac surgeries are rarely performed in specialized hospitals, so few patients are available for robotic surgery. On the other hand, Sejong Hospital had more than 1,000 cases per year of cardiac surgery as a hospital specialized in heart diseases, so da Vinci robot could be applied. Recently, Sejong Hospital has successfully operated a cardiac myxoma patient using a robot.
