To settle long-term outcome after surgery for supravalvular aortic stenosis in the Williams-Beuren syndrome, we reviewed the records of 6 patients who had repair of the localized form (n = 5) or diffuse form (n = 1) at our Institution from 1965 to 1971. Four patients were females and 2 males, ages at operation ranged from 9 to 16 years (mean = 13 +/- 2.37 years). In all the patients was present the typical elfin facies with mental retardation and reduced I.Q. Preoperative omeral pressure was different between left and right arm (89 +/- 7/67 +/- 8 vs 105 +/- 8/77 +/- 4). Chest X-ray showed and enlargement of the cardia silhouette in all the patients. Cardiac catheterization, performed in all the patients, allowed diagnosis of supravalvular aortic stenosis and, in one case of subaortic stenosis associated. Intraoperatively a coronary tree enlargement was found in all cases with particular involvement of the right coronary in two patients. The mean diameter of the ascending aorta was 5.67 +/- 1.97 mm but the smallest (3 mm) was in the diffuse group. In group with localized stenosis the aortic root was enlarged with a teardrop patch in Dacron (n = 4) or a simple transverse suture after a longitudinal incision (n = 1). A pantaloon-shaped patch was necessary in the diffuse form case. There were no operative deaths and all the patients were discharged from the hospital after 2 weeks. A clinical follow-up was possible in all the patients (10%) extended from 25 to 30 years (mean = 27.7 +/- 2.19 years); there were no late deaths and at presents time the mean age of the patient is 40 +/- 3 years. All patients were in functional class I or II. There was no significant difference between patients with a teardrop-shaped or pantaloon-shaped patch in terms of late gradient, survival, or aortic insufficiency studied by Echocardiography and color-Doppler. Of six patients two are living with parents or relatives but four are in a farm-college for disable people working and having some responsibility. We conclude that surgery for the correction of supravalvular aortic stenosis in Williams-Beuren syndrome is mandatory and both the procedures with patch techniques provide excellent long-term results of gradients and aortic valve competence. Moreover the patients after the operation can have a normal activity with a satisfactory style and expectation of life. |
