The survey was conducted by Associate Professor Kaoru Murase of the Graduate School of Systems and Natural Sciences, Nagoya City University, and the Department of Cardiovascular Surgery of the Graduate School of Medicine, using surgical data for congenital heart disease from 2007 to 2014 collected by the Japanese Society of Thoracic Surgery. analysis.We compared the number of operations for complex heart malformations caused by disorders in the early stages of cardiac development before and after the nuclear accident.

　According to the report, the number of operations for complex heart malformations for babies increased by about 14.2% after the nuclear accident, but there was no significant change in the number of operations for 1 to 17 years old.Complex cardiac malformations are disorders that require advanced surgery, and although the number of surgeries does not exactly match the number of occurrences, it is thought to be closely related.

　When the research group reclassified and analyzed the data of the Japanese Society of Thoracic Surgery based on the embryology of the heart, the disorder was not limited to a specific stage of heart development, but the early stage of heart development was widespread. It was suggested that he may have been impaired.

　The increase in complex heart malformations after the nuclear accident has also been reported after the Chernobyl accident in the former Soviet Union in 1986, but the evaluation has not been determined due to inadequate investigation methods.

　The results of the study were published in the journal of the American Heart Association, published by the American Heart Association.
