Long-term follow-up after palliative operation for univentricular heart

Data are presented from 84 patients (45 males, 39 females), aged 6 days to 25 years (mean 10 years), with univentricular heart who underwent a palliative surgical procedure. The mean follow-up period was 5 years (range 1 month to 25 years). Of the 84 patients, 33 died and 51 are alive. The survivors were 1.5 to 41 years (mean 15). Systemic pulmonary artery shunts alone were performed in 43 patients, pulmonary artery banding in 15, and a combination of procedures in 26. Five years after diagnosis, 70% of patients with type A and 54% with type C univentricular heart were alive, with no statistical difference in survival between the patient groups. Because of the high attrition rate in these patients despite palliation, further attempts to perfect corrective surgery appear justified.
