Factors influencing survival in total anomalous pulmonary venous drainage

Surgical repair of total anomalous pulmonary venous drainage was performed on 20 patients in 1977-1986. In univariate and multivariate and survival-curve analyses of clinical, anatomic and haemodynamic features, elevated diastolic pulmonary artery pressure was the only parameter prognostic of total mortality. The early mortality rate was 25% and the 5-year survival was 65 +/- 10.6%. Anastomotic stenosis occurred in four patients, three of whom underwent reoperation; one patient was twice operated on for such stenosis.
