Background: There have been few detailed reports on the gender ratio of patients with congenital heart disease in Japan, so we investigated the gender ratio of patients undergoing congenital heart disease surgery.
Methods: Based on the NDB open data of the Ministry of Health, Labor and Welfare, we calculated the number of insured cases of surgery for congenital heart disease by surgical procedure and gender over the seven-year period (Fiscal Year 2014 to Fiscal Year 2020). The gender ratio for each disease derived from the surgical procedures was compared with that in previous publications.
Results: The total number of surgery over the 7-year period was 58,635, performed slightly more for female than male (26,553 vs. 25,643). In terms of surgical procedure, there were 214 cases of vascular ring or interrupted aortic arch surgery (82.9% were male), 868 cases of transposition of the great arteries (74.2% were male), and 1,482 cases of atrial septostomy (65.4% were male). Conversely, there were more female than male among 6,977 cases of patents ductus arteriosus surgery (39.2% were male), 932 cases of complete atrio-ventricular septal defect surgery (40.0% were male), and 13,837 cases of atrial septal defect closure (40.4% were male). The gender ratio for each disease identified from the surgical procedure was higher for vascular ring or interrupted aortic arch and complete transposition of the great vessels, while the girl ratio was higher for patent ductus arteriosus, complete atrioventricular septal defect, and atrial septal defect.
Conclusion: The gender ratio of congenital heart disease by surgical procedure in Japan was clarified, and a trend of gender ratio of congenital heart disease was inferred.
