Background: This paper reviews our experience retrospectively to examine the clinical results and effectiveness of lateral tunnel (LT) and extracardiac conduit (ECC) Fontan procedures at a single institution.
Material and Method: One hundred and sixty five Fontan procedures were performed (67 LT and 98 ECC) between January 1996 and December 2006. Preoperative and postoperative hemodynamic values, arrhythmia, hospital and intensive care unit stay, chest tube drain, morbidity and mortality were reviewed.
Result: The overall operative mortality in the LT and ECC groups was 4.5% (3) and 2.0% (2), respectively. There was a significant difference in the immediate postoperative transpulmonary gradient (LT 8.5±2.5 vs ECC 6.6±2.4, p-value＜0.001) and central venous pressure (LT 18.3±3.8 vs ECC 15.6±2.4, p-value=0.001) between the two groups. The mean follow-up in the LT and ECC groups was 74.1±31.5 and 38.1±29.1 months, respectively. There was one late death. The actuarial survival at 10 years in the LT and ECC groups was 92% and 89%, respectively. In arrhythmia, the ECC patients showed a slightly low incidence but the difference was not statistically significant.
Conclusion: Both the LT and ECC Fontan procedures showed comparable early and mid-term outcomes in terms of the surgical morbidity and mortality, postoperative hemodynamics, and mid-term survival. The ECC Fontan procedure reduces the risk of arrhythmia in the follow up period.
