Key result
Atrial redirection surgery (Mustard or Senning procedure) was associated with favorable long-term outcomes at a median 32 years, with 69.6% of patients in NYHA class 1 and a mean RVEF of 53.7%.
Why the study?
Patients who have undergone Mustard or Senning atrial redirection surgery for transposition of the great arteries require lifelong follow-up.
Cohort (n=46)
No
Adults surviving over 30 years after atrial redirection surgery for transposition of the great arteries generally maintain good functional status and preserved systemic right ventricular function, although objective exercise capacity is reduced.
Supports surveillance of systemic RV function in TGA survivors; extends limited long-term cohort data to median 32 years post-atrial redirection.

Morrison et al. (2019) conducted a cohort in Transposition of the great arteries (n=46). Mustard or Senning procedure was evaluated on Clinical state, NHYA class, cardiopulmonary exercise testing, NT-proBNP measurement, and recent cardiac MRI findings. Atrial redirection surgery (Mustard or Senning procedure) was associated with favorable long-term outcomes at a median 32 years, with 69.6% of patients in NYHA class 1 and a mean RVEF of 53.7%.
