Key result
Complex TGA linked to ~8-fold higher moderate neo-aortic regurgitation after Jatene surgery.
Why the study?
The behavior and risk factors of neo-aortic valve regurgitation after Jatene surgery for TGA in the late postoperative period were not well characterized.
Does complex TGA anatomy increase the risk of neo-aortic valve regurgitation and neo-aorta dilation after Jatene surgery compared to simple TGA?
Population
127 patients after Jatene surgery for TGA with postoperative follow-up
Comparison
Simple TGA group vs complex TGA group
Design
Observational cohort study at a single institution
Follow-up
Mean 7.4 ± 4.7 years

Does complex TGA anatomy increase the risk of neo-aortic valve regurgitation and neo-aorta dilation after Jatene surgery compared to simple TGA?
Absolute Event Rate: 44.8% vs 5.9%
p-value: p=<0.0001
Neo-aortic valve regurgitation after Jatene surgery is a time-dependent phenomenon strongly associated with preoperative pulmonary artery diameter and complex TGA anatomy, requiring long-term echocardiographic surveillance.
Martins et al. (2018) conducted an observational in Transposition of the great arteries (TGA) post-Jatene surgery (n=127). Complex transposition of the great arteries vs. Simple transposition of the great arteries was evaluated on Moderate neo-aortic valve regurgitation (p=<0.0001). Complex transposition of the great arteries was associated with a significantly higher rate of moderate neo-aortic valve regurgitation compared to simple anatomy (44.8% vs 5.9%, p<0.0001) after Jatene surgery.
