Methods:We collated the nationwide data on congenital heart operations performed between January 2015 and December 2016 from the Japan Cardiovascular Surgery Database（JCVSD). The mortality and morbidity data for the 20 most-frequently performed procedures were analyzed. We also classified the surgical centers into three groups, according to the number of cardiopulmonary cases over a year and estimated the institution-wise distribution of major operations. Results:The mortality rate of the ASD and VSD repair procedures was ＜1%, while the mortality rate of procedures including TOF repair, complete AVSD repair, Rastelli operation, CoA complex repair, bidirectional Glenn and TCPC was found to be between 2-3%. The mortality rate of surgeries such as the Norwood procedure and TAPVC repair was comparably higher（＞10%). These complicated procedures were mainly performed at the surgical institutes handling a large volume of cases. Conclusion:Using the JCVSD, the nationwide data of congenital heart surgery, including postoperative complications, were analyzed.
