Because congenitally corrected transposition is a rare congenital anomaly, little is known about the prognosis of patients with this syndrome. The present study evaluated the functional status and clinical course of 73 patients (42 male and 31 female) aged 10 days to 73 years. Follow-up was 1 week to 37 years (mean 12.7 years). Particular attention was paid to the systemic right ventricle, considering the current controversies about long-term right ventricular function. Survival of patients with this condition in general was significantly below normal. The total mortality rate was 11% (8 patients) after a mean follow-up of 12.7 years (range 10 days to 37 years). Mean age at death was 18.5 years (range 6 days to 63 years). The mean age of the survivors at latest follow-up was 21.4 years (range 4 months to 73 years). In most patients, right ventricular function deteriorated and tricuspid valve regurgitation increased, which began at a very young age. Patients without associated lesions developed complications at a higher age compared with the total group. Right ventricular and tricuspid valvular function deteriorated more frequently in patients following intracardiac operation (28% and 52%, respectively) compared with patients undergoing palliative intervention (16%) or no surgery at all (28%). We conclude that survival of patients with this condition is substantially reduced compared with the natural history of an age- and gender-matched general population. This could be explained by the associated cardiac defects, but also by the anatomic condition itself.
