Department of Cardiovascular Surgery

We, cardiovascular surgeons, perform surgical treatment of various congenital heart diseases, mainly of neonates and infants, with the support of cardiopulmonary bypass when necessary.
 Congenital cardiac disease is seen in 1.0 % of neonates. One third of these children needs some surgical treatment in their neonatal or early infantile periods. Although the initial operation could completely repair the defects in some patients, the other many children require multiple staged operations. For these children, we plan to complete the series of the treatment, including the last definitive surgery before the school age.
 We deal all kinds of congenital heart diseases. After several diagnostic procedures such as cardiac catheterization and echo cardiogram by the pediatric cardiologists, surgical treatment is planned in each patient on the best optimal time of life. A half of the patients undergo the operation under 1 year of age.
 For the definitive repair of the intracardiac defects, we usually perform open heart surgery under cardiopulmonary bypass to keep circulatory and respiratory conditions safe and to maintain the cardioplegic arrest during the procedure. So-called palliative surgeries such as systemic pulmonary shunt, pulmonary artery banding and ligation of the patent ductus arteriosus usually do not require cardiopulmonary bypass.
 Cardiovascular surgeons cooperate with pediatric cardiologists and intensivists in taking care of the post-operative patients. Pediatric cardiologists manage the medical treatment, the follow-up examination and the guidance of daily life in the outpatient department.

 From 1981 to 2020, 6693 cases including 3431 open heart surgery have undergone operations in our department. In the last 5 years between 2016 and 2020, there were only 6 surgical deaths out of 1307 of all cardiac surgical cases including 5 cases who died among 683 open heart surgery (The mortality rate was 0.7%, lower than the national average of 1.0%).
