[Surgery in complex forms of transposition of the great vessels: long-term results in a series of 100 cases]. / La chirurgie des formes complexes de la transposition des gros vaisseaux: résultats à distance d'une série de 100 cas.

A series of 100 patients with complex forms of transposition of the great arteries (TGA) were operated upon over a 10 year period. Group 1 consisted of 13 TGA with pulmonary stenosis (PS), usually treated by an atrial baffle and direct repair of the stenosis. There was no operative or late mortality in this group and the long-term results were generally good (10/13). Group II comprised 29 TGA with ventricular septal defect (VSD) and PS. Seven Rastelli procedures gave 4 good results. Twenty two operations, associating atrial baffle, repair of VSD and PS (17 direct procedures, 5 left ventricle-pulmonary artery tube) were associated with a high mortality (5 operative and 4 late deaths) and 10 good long-term results. Group III comprised 58 TGA with VSD. Up to 1977 (n = 33) treatment consisted of atrial baffle + repair of VSD +/- removal of previous banding. Mortality was high (11 operative and 8 late deaths) with only 8 good long-term results. Since 1977, these patients have been treated by complete anatomical repair, the operative mortality of which is higher in the period under study (9/23) but the long-term results are much better. The surgical indications in our Department are based on the analysis of these results. In Group I only very significant PS is treated, either by left ventricle-pulmonary artery tube or direct repair depending on the form of the stenosis. In Group II, where the results based on atrial baffle are poor, a Rastelli procedure is preferred and especially its variants which avoid the use of prosthetic materials on the pulmonary trunk. In Group III, anatomical correction at the level of the great arteries is the routine procedure, the only point of discussion being the possibility of prior banding.
