| Popis: | Objective: Assessment of the Lecompte procedure, our repair method of choice in malposition of the great arteries with pulmonary stenosis. Methods: A retrospective analysis of 42 patients (median age at operation, 1.4 years) operated on between 1986 and 1999 for various forms of great artery malposition, ventricular septal defect, and pulmonary stenosis. Relevant associated findings included the insertion of a tricuspid papillary muscle on the conal septum (nine patients), absence of conal septum (six patients), hypoplasia of a side pulmonary artery (four patients), and hypoplasia of the right ventricle (one patient). A preliminary systemico-pulmonary shunt was created in 28 patients and a cavo-pulmonary anastomosis in one patient. At operation, the conal septum (whenever present) was resected (36 patients), the pulmonary bifurcation was usually translocated over the ascending aorta (37 patients), and the main pulmonary artery was enlarged with a patch of pericardium. A monocusp valve was fashioned within the patch in 40 patients. The follow-up information was complete in 32 patients and ranged from 0.4 to 14 years (mean, 5.4 ^ 3.2 years). Results: The survival rate at 5 years was 92 ^ 5%. Three patients died postoperatively (mortality, 7%) and none during follow-up. The freedom from reoperation was 86 ^ 8 and 51 ^ 22% at 5 and 10 years, respectively. Six patients were reoperated, all for a pulmonary stenosis. Calcification of the monocusp patch was present in all. Pulmonary stenosis developed in three further patients: one underwent percutaneous dilatation and two are awaiting surgery. No procedural factors thought to have a potential correlation with the development of right ventricular outflow tract stenosis could be individualized on univariate analysis. Conclusions: The Lecompte procedure, which allows early repair of these defects, provides overall good results. The need to reoperate on the right or left ventricular outflow tract seems reduced in comparison with the Rastelli operation, the other alternative. q 2001 Elsevier Science B.V.
