PG - 462-73 AB - OBJECTIVE: To evaluate the cardiovascular findings and clinical follow-up of patients with Williams-Beuren syndrome. METHODS: We studied 20 patients (11 males, mean age at diagnosis: 5.9 years old), assessed for cardiovascular abnormalities with electrocardiography and Doppler echocardiography. Fluorescence in situ hybridization (FISH) was used to confirm the diagnosis of the syndrome. RESULTS: Elastin gene locus microdeletion was detected in 17 patients (85%) (positive FISH), and in 3 patients deletion was not detected (negative FISH). Sixteen patients with a positive FISH (94%) had congenital cardiovascular disease (mean age at diagnosis: 2,3 years old). We observed isolated (2/16) supravalvular aortic stenosis and supravalvular aortic stenosis associated (11/16) with pulmonary artery stenosis (4/11); mitral valve prolapse (3/11); bicuspid aortic valve (3/11); aortic coarctation (2/11), thickened pulmonary valve (2/11); pulmonary valvular stenosis (1/11); supravalvular pulmonary stenosis (1/11); valvular aortic stenosis (1/11); fixed subaortic stenosis (1/11); pulmonary artery stenosis (2/16) associated with pulmonary valvar stenosis (1/2) and with mitral valve prolapse (1/2); and isolated mitral valve prolapse (1/16). Four patients with severe supravalvular aortic stenosis underwent surgery (mean age: 5.7 years old), and 2 patients had normal pressure gradients (mean follow-up: 8.4 years). CONCLUSION: A detailed cardiac evaluation must be performed in all patients with Williams-Beuren syndrome due to the high frequency of cardiovascular abnormalities.
