Outline of Final Research Achievements

Detection rates for moderate to severe congenital heart diseases in prenatal screening of fetuses are investigated in Japan. Average of detection rate is 0.41 in Japan and there are significant differences of detection rate among prefectures and types of congenital heart diseases in Japan. A Japanese map and brochure of detection rate in each prefecture is created. Detection rate in Japan is lower than European countries and American requiring further improvement of the system of prenatal diagnosis for congenital heart diseases in all over Japan.

Academic Significance and Societal Importance of the Research Achievements

日本における先天性心疾患の胎児診断率は欧米諸国と比較すると全国的に明らかに低く、地域差が極めて大きいことが判明した。地域による胎児診断率の差が大きいことも判明した。欧米諸国では全国的な体制整備により先天性心疾患の胎児診断率向上をすすめている国も多く、本研究結果を元に日本の医療体制整備を進めていくことが周産期医療の改善につながる。
