Abstract

OBJECTIVES: The purpose of the study was to examine long-term outcome after traditional surgical treatment of corrected transposition of the great arteries to provide a basis for comparison with new procedures, such as the double-switch or Senning-Rastelli procedures.

METHODS: Patient- and procedure-related variables in 123 patients with corrected transposition and 2 functional ventricles operated on between 1963 and 1996 were analyzed. Patients with intracardiac procedures underwent either a traditional 2-ventricle repair or a Fontan procedure.

RESULTS: The 1-, 5-, 10-, and 15-year survivals after the operation were 84%, 75%, 68%, and 61%, respectively. Patients requiring tricuspid valve replacement (27 patients) at any time during follow-up had a significantly worse outcome ( P < .001; hazard ratio, 4.4), whereas the best outcome was seen in patients undergoing the Fontan procedure (17 patients, 0 deaths). Right ventricular end-diastolic pressure of greater than 17 mm Hg before the operation ( P < .0001), complete heart block after the operation ( P = .001), subvalvular pulmonary stenosis ( P = .013), Ebstein malformation of the tricuspid valve ( P = .025), and preoperative systemic (right) ventricular dysfunction ( P = .041) were identified as risk factors for death at any time by means of univariate analysis. Ebstein malformation of the tricuspid valve ( P = .036; hazard ratio, 1.5) was identified as a risk factor for death by multivariate analysis.

CONCLUSIONS: The long-term outcome of patients with corrected transposition after a classic surgical approach is unsatisfactory. The poorest outcome was seen in patients who required tricuspid valve replacement either at their initial operation or later during follow-up. Alternative surgical approaches, such as the double-switch, Senning-Rastelli, or Fontan procedures, are likely to have better long-term results, especially in the highest risk groups.
