Twelve patients underwent surgical correction of total anmalous pulmonary venous connection (TAPVC) between Sep. 1989 and May 1993. There were 9 boys and 3 girls whose age ranged from 10 days to 17 month (medial 1.2 month). Six patients were less
than 1
month of age ar operation. The anomalous drainage was supracardiac in 6, cardiac in 2, infracardiac in 2, and mixed in 2. There were 3 early death, and its mortality rate was 25%. There were no operative mortality after Sep. 1991. Age at
operation,
presence of preoperative pulmonary venous obstruction, preoperative assited ventilation and type of anomaly did not affect early mortality.
Late pulmonary venous obstruction was developed in 4 patients between 1 month to 4 month after operation. Among these patients, 2 were died and one was reoperated and well, and the other one was not operated because of patient's refusal. We
conclude
that late pulmonary venous obstruction is fatal and its early detection and correction is important for improving late survival. (Korean J Thoracic Cardiovas Surg 1994; 27:260-265)
