Background- In recent decades, advances in congenital heart surgery have dramatically increased the survival of infants with critical congenital heart disease.
Methods- To determine the outcomes after the Fontan and total cavopulmonary connection (TCPC) procedures, we investigated 51 patients with single ventricle who underwent the Fontan (27 cases) and TCPC (24 cases) procedures between 1991 and 2001.
Results- Five patients (9.8%) died after surgery. Forty-six patients were followed for a period of 42.9±32.1 months. Thirty-eight of them (82.6%) were alive with a better New York Heart Association functional classification than preoperatively. Ejection fraction was more than 60% in 28 cases (84.4%) one year after the operation. Complications were seen in 23 patients after surgery: 8 with early complications, 12 with late complications and 3 with both early and late complications. Overall arrhythmia was detected in 34.8% of our patients during their follow-up. Reoperations were necessary for 15.2% of our patients.
Conclusions- The surgical approach to congenital heart defects continues to involve a series of complicated operations with significant associated mortality and morbidity.
