Analysis 2.5 - Table 7 shows that patients submitted to the Jatene surgery with a moderate neo-aortic valve regurgitation had a higher age mean (p=0.0145). Of the 127 patients studied, 2 patients in the complex TGA group required valve change because of regurgitation progression during data collection, the reoperation rate being 1.5%. Discussion Reintervention due to neo-aortic valve regurgitation after Jatene surgery was first reported in 2009 in a 16-year-old adolescent. 16 That report concluded that neo-aorta dilation was present in two thirds of the patients and that moderate regurgitation was observed in 15%, emphasizing the need for careful follow-up in that group of patients.
